Regarding user collaboration during the data migration process, it falls more or less on the IT side of things to ensure that the customer's experience is optimal. With HPE Zerto Software in a different environment, once things are set up correctly from a networking perspective, we can spin up almost anything in the environment to match what the customer's experience was inside their home environment. If they use a Cisco firewall or Palo Alto firewall, we could put a Palo Alto firewall in the disaster recovery site, which gives them the ability to use, for instance, VPN. If they connect via VPN, they can use that exact same VPN login information to get into their new environment that sits somewhere else. This cuts down the disruption time of how long it takes for someone to migrate a firewall physically, and we could kind of do a virtual option for that as well. HPE Zerto Software opens the door for more virtual options for clients who may not have the ability to do it physically. As time goes on and new operating systems come out, HPE Zerto Software is releasing updates relatively often. What I find is that we are working in an environment where not every customer is updating every day to the latest version of, for instance, the latest hypervisor version or the latest operating system. The one thing that I would like to get improved is more legacy support for customers. Once we go past a certain version in HPE Zerto Software, it does not support certain versions. For us, many of our customer workloads are VMware based. VMware has a functionality where they do hardware versions and have their own sets of hardware versions. Many clients, once they update their environment, will update and create servers based on their brand new environment that is not necessarily supported by HPE Zerto Software right then. HPE Zerto Software, while being agnostic, will copy that data, but the hardware version for that new VM may not be supported. Because we use it in a cloud-based platform and we are doing multiple users, we cannot just upgrade one part of it because then it will affect all of these other customers. I am not sure what the right phrasing would be to describe what they need to do, but it would be more support of older systems as well as having a way to manage those persons that may be a little bit trigger-happy when it comes to updating, so we do not have to do updates across the whole entire board in order to just appease one client. We try our best to keep the client to the point where they do not do this type of thing, but we only could do so much.
There are few areas for improvement that are mostly technical. It has limited support mostly for VMware environments; they are trying to reduce support for Hyper-V and now bring it back, but it's not working as easy with VMWARE. There is a problem where you need to perform a full sweep to back up and sync a VM from the beginning, which occurs in some scenrios. There are times you need to restart synchronization from the start, which is a heavy operation without clear reasoning, consuming a lot of resources.

The main improvements needed are related to historical data comparison and analytics, and the challenges involve reliance on other software and cross-checking logs. If we could have an end-to-end DR solution in one environment, it would be much easier without relying on multiple tools. The biggest area for improvement in HPE Zerto Software is probably in historical data comparison and enhanced analytics. Future features should reduce reliance on cross-checking logs and other solutions.

I hesitate to offer improvements for HPE Zerto Software since I appreciate it so much; the user interface is good, and the actual data under the hood is good. It keeps working, it's fast. However, it could benefit from tighter integration with VMware. They have a head start on proving that the new version will work. When cybersecurity events happen and we have a new release that we need to deploy quickly, they have a 90-day window to remediate that, but I need to deploy it before them, and I can't.

We encountered some issues with HPE Zerto Software. The main concern involves the Delta Sync that triggers when changing the recovery direction. For large virtual machines of several terabytes, this process can take considerable time. As a bank, we are required by regulators to run regular DRC scenario testing for one week from the DRC site. When changing replication, the Delta Sync takes approximately six hours for six terabyte virtual machines. During this time, the virtual machine is inaccessible. If another major issue arose requiring us to return to the PDC, we would have to wait six hours for the Delta Sync to complete, which would result in a test failure. This represents our biggest challenge.

HPE Zerto Software can be improved by allowing a system inside my makeshift vault to reach out to the other system and pull backups inside, which would let me punch fewer holes. Currently, my understanding is you have to have two systems that are interconnected. Based on how I've built it, if I could have a system inside my makeshift vault reach out to the other system, that would be more secure. Right now, both systems have to talk to work. We've completely rebuilt our infrastructure inside, including firewalls and everything, inside a basic vault. It has the same concept. For that system to replicate, we have to have holes in the firewall for the outside system to reach in to connect to the HPE Zerto Software inside. A lot of the wording isn't very clear. If you don't know what you're looking at, it just oesn't make sense when you are setting it up.

An improvement I would like to see in HPE Zerto Software is the ability to start protecting bare-metal configurations, as today it only handles virtualized workloads. I would love to see some progress in bare-metal protection. Several bare-metal use cases also need similar RTO, RPO, and business criticality thinking, which would be fantastic if HPE Zerto Software ventures into the bare-metal space.
To improve HPE Zerto Software, it would be helpful to make it more affordable. In the next release, I would like to see additional interfaces with HPE, as I talked to HPE about some storage solutions and know there is something in the works possibly between HPE Zerto Software and HPE that would make my life easier.

If we could integrate our AIOps solutions and incident management capabilities within HPE Zerto Software, that would be beneficial, as it would enable us to automatically bring the DR site online when a major incident is detected, eliminating human involvement and making the process quicker than manual decision-making.

When we did our test this year with HPE Zerto Software, we had some failures that we weren't expecting. The challenge was realizing there was data corruption, and fortunately we found it before we committed the failover, so we could fail back. We could resync it, and we weren't in an actual disaster. If there's any way to validate that data on the recovery site without having to manually go in and do failover testing and try to validate, that would be a feature that would be really nice. We're not sure why we had some corruption, however, we did the resync and it seemed to bring it back up and fix the problem. That's probably the biggest area I'd ask about - some way of validating the recovery sites in an automated fashion.

With the current updates primarily on the Azure side of it, documentation could be improved. That's not necessarily Zerto's problem since Azure is constantly changing things; Zerto will put something out, but Azure then will change it, and sometimes it's hard to follow that documentation. HPE Zerto Software can be improved by keeping up on top of the Azure changes happening there, trying to smooth that process out, because there are many steps that you have to take in Azure, and that's not necessarily HPE's fault, it's just how Azure functions.

I run a very dense VM-to-host ratio in my environment. Whenever maintenance is being performed on a host, all the VMs on that host have to be powered down and/or moved off to complete that maintenance cycle. It is frustrating when the protection of VMs doesn't get relocated to another host before the replication appliance powers down. It sometimes works great, but if the host has a lot of VMs on it, there may not always be enough time to relocate all of the VMs from a protection group standpoint to other hosts before the replication appliance that Zerto uses to manage that powers itself down. In such a case, you are breaking replication for the duration of that maintenance, and that can cause some support issues when you bring it back online, where you have to go in and manually recover it. I know they added improvements over the years. It's not as bad as it used to be, but at times, I still end up breaking replication when I do maintenance on my hosts.

Near-synchronous replication has some trade-offs. With near-synchronous replication, we get almost all the information up to date at the destination site, but the trade-off is that sometimes that could take a lot of CPU cycles, network bandwidth, and troubleshooting. A few versions back with Zerto, there were some bugs in the software that were causing constant replication back and forth that was driving a lot of network bandwidth utilization over the network, and we did not know why until we found out it was a bug. It depends on what your business or application really requires. If it requires near-synchronous, you have to enable that. However, if Zerto can make it easier or have a smaller footprint by sending larger payloads or having network compression, it will be a little bit easier. On wide area networks and local area networks, that would definitely be preferred. We have had some issues running Linux virtual machines on the new version. There were some issues with virtual replication adapters on Cisco UCS hosts running VMware vCenter 8. There were several things we had to do with installation and getting the replication adapters to work. Integration with Keycloak for Active Directory authentication using new Linux VMs was challenging, but it is now functioning well.

The biggest area for improvement is the technical support side. Although it has improved somewhat, after the HPE acquisition, it became apparent that level-one technical support was moved to groups unfamiliar with the Zerto product. As experienced users of Zerto, when we need to open a ticket, dealing with level-one technical support can be tough. We often need to escalate immediately due to our internal skill set surpassing level-one support capabilities. That is the biggest complaint we have with Zerto.

When it comes to failover tests, we would like to be able to take that extra step to shut things down and see what it looks like at the other site versus just doing it in a virtual environment. That is one thing I would push back on them. I would like the ability to perform actual failovers more easily compared to our current process. In the event of an issue, we can switch and bring back servers smoothly, but when we do the tests, currently, Zerto's test failovers are virtual. We cannot get end users to come access those systems. I would like to be able to do a test where we failover and rebuild the network connections so that end-users can hit that center or server and test. Improving testing capabilities would be advantageous. When it comes to deployment, one improvement could be being able to visually see virtual private groups and server names. Although the reporting is comprehensive, occasionally, people use long names that do not display fully on the monitoring page. Despite this minor issue, deployment has been easy, and we rarely need support.
Some of the cloud instructions around VNets and peering of networks could be clearer with some best-case examples. It is more complicated once you move into the cloud than running it on-premises.

I am primarily interested in Zerto as a backup and recovery mechanism, and it does a phenomenal job of that. It is an enterprise-grade tool, and enterprise-grade tools tend to be complex. They can be a little difficult to use at first until you learn them. It is not reasonable to suggest making it easier to use because it is an enterprise-grade tool, and it is very robust. Therefore, it is not going to be easy to use. I just have to spend the time to learn it and become good at it. I am very pleased with it as is, but the ease of use of the restoration utility could be challenging initially.

The main issue with Zerto is its user interface, which lacks flexibility and presents a steep learning curve. To improve usability, the UI should be simplified and streamlined, making it more accessible to technical and non-technical users. Additionally, the UI should be better aligned with the platform's various options and features, ensuring a more intuitive and efficient user experience.
Zerto's pricing model is cost-prohibitive for small—to medium-sized businesses. Its structure limits affordability to approximately five to ten virtual machines. To increase accessibility for small and medium businesses, Zerto should consider a competitive pricing strategy, possibly including subscription-based licensing options. This would enable more organizations to utilize Zerto's services. I want Zerto to add support for Proxmox.

The primary concern expressed by all server users is the lack of robust integration features. While Zerto offers some integration capabilities, the smooth and efficient data flow between portals remains a significant challenge. The support and technical teams know this issue and actively seek user feedback, but progress has been slow. The current process, involving multiple platforms and a database management system bottleneck, is time-consuming and inefficient. Additionally, while reporting and dashboard features exist, real-time reporting and mobile functionality require improvement. The user interface could be more intuitive and user-friendly. Customization, a critical requirement for government clients, is another concern. Implementing requested changes is often time-consuming and expensive, hindering adaptability. Addressing these integration, reporting, user experience, and customization issues is essential for improving customer satisfaction and retention.

Zerto integrates with vCloud Director to protect workloads deployed there. However, it would be beneficial if Zerto also offered integration with other cloud management platforms, such as VMware Aria Automation. For example, Site Recovery Manager recently introduced integration with VMware Aria Automation, allowing the protection of workloads deployed through Aria Automation. This functionality, including site recovery management, is currently not available in Zerto. Zerto's strength seems to lie specifically in its VMware capabilities, which could be an area for improvement. Another point to consider is the potential for Zerto drivers to cause issues in ESXi environments. In some cases, users have reported problems and discovered that the Zerto drivers are not verified by VMware. While HPE is a technical alliance partner for Zerto, improved collaboration between VMware and Zerto regarding driver validation would be valuable. This information seems to be missing at the moment. We are currently in touch with our technical account manager to clarify this.
The product could benefit from improvements in automation, specifically in the area of failovers. Currently, the process is largely manual, and introducing automated failovers after a certain time threshold would enhance efficiency and responsiveness. Automated failovers can reduce the dependency on manual intervention, allowing for quicker and more proactive responses to disruptions. In the next release, the inclusion of scheduled or automated failovers would be a valuable addition. This feature would empower organizations to set predefined parameters and triggers for failovers, ensuring a timely and automated response to potential issues. It not only streamlines operations but also adds an extra layer of reliability to the overall disaster recovery strategy.
It would be nice if Zerto offered OVFs, which are custom-built VMs that you can install on your virtualized environment. At the moment, I have the Zerto sitting on two custom-built Windows servers, which creates a lot of overhead.

Their data backup and restore have some ways to go. We looked at replacing our traditional backup system with Zerto and found it was lacking about a year ago. We have Commvault, which is very customizable and feature-rich in comparison. Their offering needs to be more robust.

I don't feel like we're a big enough customer to warrant being called every week or every month but it would be good to get a little bit more contact with a salesperson or engineer group. Our account executive is very good. He's done a great job, but it was hard for him to tie down an engineer. It was a little bit of a strain to get somebody lined up to show us what version 10 was about. Once we got it, it was perfect. It would be nice if it could be easier to do that. They have VPGs and VRAs. The management of that when trying to do a VMware upgrade can get a little finicky. You have to bring nodes or hosts up and down where the VRAs are running on the hosts. Sometimes the VRAs won't come back up or they may not respond. So when you're done doing your work, it could be that you have fifteen servers that are not replicating. So you'll have to stop, delete, manually remove what you need to do, recreate the VRA, and that's easy enough but you have to go through and do that, and then resync. That's part of IT. They are a little finicky. Version 9.7 has been a little easier to work with, and it integrates with VMware a lot easier. It shuts down the VRAs. The VRAs are finicky about how they get shut down.

Zerto could be easier to configure when we need to perform data testing and establish network connectivity outside of the isolated environment. We encounter situations where there is a desire to test a printer during disaster recovery testing. However, due to the presence of an isolated environment, doing so can result in complex configurations. Zerto needs to improve its support for VMware Lifecycle Manager. This creates a problem with VMware's ability to automate the complete VMware stack upgrade.

One concern we have is the speed at which Zerto maintains compatibility with VMware and different versions of VMware. We are specifically worried about potentially major security issues with our current ESXi version and whether upgrading it would cause any problems or compatibility issues with the Zerto version we are using. It is crucial for Zerto to collaborate closely with VMware in order to promptly test updates.

You can use Zerto as a backup product, but in the discussions that I have had with them about the product, they don't really sell or talk about that feature as much. So I would be interested in improvements related to using it as a backup. If I could consolidate and use Zerto for disaster recovery as well as everyday backup and restore for situations where I need to recover something, that would be helpful. It has some of that functionality, but it's not something they promote a lot. They should point out the benefits of using Zerto as a backup and recovery product instead of just a DR product. With Cohesity, we keep a limited amount of backups, about 14 days. That way, we can recover an individual server within the same site or we can restore data or databases that we need, in a non-DR way. We use it for typical day-to-day backup and restore. If we could use Zerto in a similar fashion for everyday backup and recovery scenarios, that would be another area where we could consolidate into a single application.

They just came out with improvements for ransomware protection last week. I haven't used them yet but, overall, security and preventing ransomware is really a hot topic these days. I would like to see it detect when the ransomware occurs and provide more information on it.
I turned in a ticket a while back when I found a glitch within Zerto. When building out a VPG and doing the machine types within Azure, they were not coming across correctly. It would say it had a CPU and memory of a specific type, but it was not accurate. When I sent that ticket in, the support manager said that it hadn't been found before, but that my report was accurate and that it was a bug, and that they were working on it. But I've been very pleased with the updates that they put out and the service. I don't have a lot of negative things to say about Zerto.
The only challenge we have encountered is with rotating passwords on our VMware nodes. With secure boot enabled, which is the case for newer systems, it is not easy to rotate passwords and we would have to reinstall the VRAs. This is not ideal, especially when our security team wants to rotate them weekly. Aside from that, everything has gone smoothly. The updates are easy and it does not hinder us when updating the VMware. The only issue is that we have to wait three months after a major release. This lessens the complexity of the update of the software itself. Other than that, there is no issue and it does not hinder us from running different versions of VMware.

It would be beneficial if we could gain insight into DNS record reporting from the DR side, however, this is not a realistic expectation due to the fact that different companies use different hardware and different methods of DNS management. It would be advantageous if Zerto had plugins for Infoblox, Cisco, or load balancers, as this would enable us to better manage those records. Unfortunately, this is not a realistic expectation as these products are usually managed by the middleware or a network team, which has no relation to their application.

Zerto's connectivity with automation platforms could be improved. For example, vCenter can use a VMware-developed tool called Site Recovery Manager. That can be integrated with automation platforms such as Terraform, Ansible, Chef, or Puppet, to perform automated, self-sufficient recoveries to essentially avoid any downtime. To my knowledge, Zerto does not have integration with those platforms. Zerto does have an API, but a lot of those automation platforms have prebuilt runbooks to enable that process, whereas Zerto does not.

Recently, I started to try to deploy vVols instead of VMFS volumes in my VMware environment and I did encounter an incompatibility. It seems that for Zerto volumes to be protected, there's some sort of limitation with drives having to be either thick-provisioned or thin-provisioned, I forget which. But there's some sort of inherent limitation that causes an incompatibility with vVols and VMware. That has to be overcome somehow. It has to be flexible enough to be able to do its thing. And for an additional feature, and I'm not sure if this is already in the works, I would like to see improvement on the Zerto Virtual Replication appliances, so that they are a little bit more streamlined as opposed to now where they just span multiple ZVR appliances like there were gremlins. We have our three main ZVR appliances, each one of them associated with one of the hosts, but as this thing grows it just spawns unlimited numbers of additional ZVR appliances and you end up with a bunch so that you can't really tell which is which. Better management of those ZVR appliances would help, if you have to vMotion them off of something. If you want to migrate a ZVR appliance from one storage to another, you can't really tell what's what and there are multiple pieces related to this ZVR appliance. I would like to see that cleaned up a little bit with better management features for ZVR appliance maintenance overall.

Improvements in stability would be welcome; there are some software bugs that can affect RPOs. We want more of a guarantee that we won't lose any of our backups, even in the event of a disaster. The platform measures the write speed of storage devices and gives an alert on the VPG if there is latency, but the nature of the alert suggests the solution isn't meeting the SLA. However, this shouldn't affect the health status of the backup. It should provide an express report that we should enhance our hardware rather than express latency as a threat to the backup capability.

I want to have an OVF or some local deployment where I can deploy the ZVRA rather than having to push it from the console. Some of our smaller remote sites have relatively poor bandwidth, and they can't keep up with the constant deployment stream from our center console, meaning we have to find some creative hours to get around the bandwidth bottlenecks. If I could push out a small install file, install it locally, and then reach back to the console, that would be excellent.

Zerto is more of a set-and-forget-it type of solution. As long as the replication is continuous and there are no issues, I don't touch Zerto. We don't have a lot of workload that needs to be up. We just have our web server and our applications here. Those are two main servers that we get up and running in a disaster-recovery type situation. I can't give any area of improvement from a real-world experience because we haven't had that issue, but from testing, Zerto has been working great. It is not something that goes beyond what our use case is for. When it comes to a solution, one of the things the management wants is to standardize platforms. That's why when Rubrik came out with their solution, they wanted to look at it. For instance, if you have multiple technologies, you're going to need admins to manage all those different ones. I would like Zerto to be something that fits all our needs, including the backup that Rubrik provides, but I understand that not all solutions can be that way. When I started working here, my predecessor who was managing Zerto had no documentation. So, I had to take over. No one else knew how to manage Zerto. So, there is just that type of learning process. That's why management wants to standardize on one solution so that it is easier to cross-train, but that's not Zerto's part. It just happens to be our environment and our management style. Zerto as a solution has been great for us.
More user support would be best for me because I'm not in the product all the time. So, having strong support is probably the most important decision on any products that we buy. The price is another thing that they definitely need to work on unless it has changed. I purchased mine a while back.

The time between releases is too long. Zerto doesn't seem to really keep up with the products with which they need to be compatible. For instance, the 9.5 updates 3 took about 90 days to come out after the latest version of vCenter 7.0 update 3 was released. We were facing a vulnerability, so we had to choose between patching our vCenter to address that vulnerability, which would break the Zerto operability, or leaving it as is with a potential vulnerability. That was really the main issue we ever faced with Zerto.

There's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for. With the orchestration part of the failover, with our DR and our primary sites, the IP addresses are almost identical. The only difference is one octet. With SRM, we could say during a failover change. With Zerto, we keep hearing that it's coming, but we haven't received it yet. It's a feature that would be very beneficial. It would reduce the time a little bit more.

The other improvement is working with storage vendors, like Pure Storage for the synchronization of the data similar to what SRM does. Using Zerto for the orchestration, and the hardware vendor for the replication would be beneficial.

The VPG model has caused a bit of a concern. We are considering using Zerto to replace Site Recovery Manager. SRM is very easy when we have entire data stores being replicated. We don't have to make any decisions when it comes to groupings of VMs. If we move to Zerto, which we are considering, we will have to work closely with our applications teams to create VPGs and determine how the VMs will be grouped. This will probably be beneficial in the long term, but short term it will create more work for our team. I spoke to a Zerto engineer who mentioned that we could do a VPG at the cluster level and a VPG at the datastore level. However, the one issue we've seen with VPGs is if the synchronization fails the entire VPG has to be recreated. Even though we can cover our environment at the cluster level or datastore level, that wouldn't be ideal. We really need a simpler solution for DR that will cover all of our VMs at once, instead of spending a considerable amount of time on VPG creation.
I need to get up to the latest version so I can move my journals to a particular LUN, saving them with a particular storage altogether, rather than with the virtual machine. This is not available until I upgrade, and I need to upgrade all my hypervisors. This would be something that would be nice to have if it could be used on older versions.

I would like to see the app be more like the analytics site. Right now, when you go into the analytics, you need to zoom in real tight on your browser.

I don't like the evacuation process. The host evacuation process could be a little simpler too. It takes our maintenance a bit longer, when we are doing host maintenance, because we still need to evacuate the vRAs manually. I know they tried to make it more automatic, but it is not quite there yet.

If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens. The other thing that I've run into lately is that when I've done a whole bunch of upgrades to systems, so they're offline, they get stuck in a pending state. You can never get them out so you have to delete and start all over again. It would be nice if they could make it a little simpler to figure out what's wrong.
We had a situation where we had to relicense VMs once they were moved over. We later found out that that feature is built-in, but it's not easy to find. The way it's done is that you have to go to the target site to turn it on. If that were explained a little bit better up front, that would be helpful.

Whenever we do a failover, there's a confirmation box that shows up later. It's a little hard to see sometimes. We'll do the failover and some preparation activities and then there's a checkbox you need to check to continue and sometimes it's small, in the corner, depending on which screen you're using. A popup to continue would be a little bit better because then you're not sitting and waiting for something and it's already there. We also had an issue with a misnamed network. They should make that a little more apparent when it's not available on the destination side. We were able to go all the way through with it, but when we did the recovery, it wasn't available. A pre-check to say, "Hey, it's not available. What network do you want to use?" would be helpful.
If we have multiple VMs in a VPG (Virtual Protected Group) and one VM is hung for DR, it holds things up. The only alternative is to create multiple VPGs. It would be nice to have one VPG where, if one VM is failing, it does not impact the overall process.

Zerto is not an API-first company, but an API-now company. A lot of the functionality that is in Zerto UI is not in the Zerto API. That is likely because it is baked in code or compiled down DLLs. Every business has to make a decision to work on something, and I don't think Zerto has committed resources to working on that part. It is a problem to do cleanup for Azure Blob Storage, recovery site storage, or whenever you remove a VM from a VPG without deleting the VPG. That needs to be improved. Doing scheduled disaster recovery connection tests, e.g., being able to migrate things up and get things working on a recovery site without needing a user to do it, would be helpful. Analytics has a 90-day window, where it keeps data. It would be nice to have on-prem storage instead of cloud storage for that so we can keep the data for longer. Unless you discover the problem within three months, you don't know that you need the data. Then, it is gone by the time you realize there is an issue. I would like to be able to offsite some data. We export our analytical data so we can keep it longer without having to script around it. It is possible right now, with the API, to script around it. However, I don't want to have to write a monthly process to export the last three months of data to a spreadsheet so I can just have it if I need it. A lot of the PowerShell documentation in some of Zerto tutorials or how-tos is a PowerShell-to-legacy sort of paradigm. It needs to be updated to at least 3, likely 5, or probably 7. It looks like it was written by someone who didn't know PowerShell, but had to learn it really fast. It does the job. If you copy and paste it, then it will work, which is something. That is way better than what a lot of people do. However, I feel like a bit more effort should be pushed towards PowerShell. I would like them to build an alerting system. I am trying to find a way to connect it to my business continuity people, so the Zerto people don't need to be pseudo-business continuity people all the time. They can just be IT people. I would like more creature comforts for the scripting engineer. It would be nice if they could expand the development community around building different APIs or API structures for Zerto.

The syncing of the replication needs improvement. My experience has been that, every once in a while, when you go to do a failover, it tells you it's not syncing. Then you have to troubleshoot and figure out why it's not fully synced up.
Zerto can improve the dashboard by making it even more simple. Right now, there's a lot on the dashboard, and it can be overwhelming. If you're an experienced user, then you'll find it easy to use, but if you're a beginner, it will take you some time.
It's hard to say where it could be improved. The few times I've had issues with the interface, which is, for the most part, intuitive, we have been able to take care of most issues without having to open a case. There are a couple of areas in the interface that are not very intuitive. Most of them are pretty easy, but there are a few areas in the journal and replication that, unless you've done it before, you really have no idea what to do. When I get to those points I'll reach out and ask for a little assistance or do a Google search to find the solution to the problem that we're having.

If something changes in VMware, it would be nice to be able to go in and change that VPG, having it update without messing up.

There are quite a few elements in the long-term retention areas that I wish were better. The bio-level recovery indexing of backups is the area I struggle with the most. That's probably because I desire to do tasks that ordinary users wouldn't do with the solution. The standard medium to the large customer would probably never ask for anything like I ask for, so I think it's pretty good the way it is. I'm excited to see some of the new improvements coming in the 9.5 version. Some of the streamlines and how the product presents itself for some of the recovery features could be better.

In general, the solution is pretty good, but because it is geared toward simplicity, sometimes, when things go wrong, the answer is not very detailed so that things can be solved quickly. If things do go wrong, it does require a little bit deeper troubleshooting to resolve the issues. That's the only area where improvement could occur. There should be a little bit more details about if things go wrong, how to remedy them. Everything is meant to be simple. When something doesn't work, even though what you were trying to do appeared to be very simple, there are probably a lot of pieces behind the scenes. So, to be able to narrow down where in those 100 steps something went wrong can be a little tricky. When there is a failure, there should be a more detailed explanation of what the error is and how to remediate it. Currently, it's a little vague. A part of that could be because we use Zerto on top of Hyper-V. VMware still has a very large market share over Hyper-V and a lot of the information and a lot of the deployment plans are geared towards VMware. So, sometimes, there are new features that first roll out to VMware and then come to Hyper-V.

The only thing we've noticed that needs improvement is the backend cleanup within VMware. There are some little issues there. I would like to see tighter integration with VMware. From a recoverability standpoint, it's great when using VMware. But what we have noticed is that orphan data is an issue within VMware. It doesn't clean up properly when you're moving stuff around.
They could improve their online documentation. From a reliability perspective, the product is around seven. It's less reliable than, others for example. They have one limitation when they have a virtual protection group that does everything. From the ease of deployment perspective, it requires expertise and time. It's not very easy to do auto-tagging or to run multiple VPG genes at the same time. So, from multi-tenant or multi-complex scenarios such as using Zerto external products, such as firewalls, while their own product is good, it's part of a larger ecosystem, that still has a long way to go. The triggering of external products could be better. Combining a master runbook and not just a single VPG or splitting the protection group from the activation plan could be better. There will be a protection policy and activation policy as being done in other products. Better tagging and better multi-term support are needed. Currently, there is no tenant admin support, only global admin support. They should work at the tenant level instead of the global admin level. Right now it's an HPE product; they're no longer a startup. We are hoping that being bought by a major company will do good for them and they'll fix what needs to be fixed. There were very good products, to begin with, and HPE should work to make it even better.

The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that we're only able to replicate one way using this solution. Now, we are evaluating the clustering of Zerto with Microsoft clustering, so we can replicate both ways and both data centers, and have the management server in both data centers. Historically, Zerto has started going into the backup space, and that is when they lost focus on keeping their replication product good. Now, it seems they're finally leaving that backup space, and they're just sticking with replication, so in version 9, they have fixed all of my gripes about the product, e.g. they now support VMware tags, Windows bringing over the time on the target side, etc. All of these little things, they are all correcting, because they're now sticking with the replication product.

Rather, Zerto should be able to handle putting various hosts, within either the source or destination side, into maintenance mode without having to worry about the vRA appliances. Sometimes, Zerto almost holds the vSphere environment hostage when it comes to taking certain actions. You really need to be cognizant about what you're about to do. They should further automate that and increase Zerto's ability to handle things like that in a very slick, automated way, without intervention. Zerto could also build more canned automation tools within their product, tools that automatically work with DNS updates to AWS or Azure. Maybe they could provide an area for scripting help or canned scripts, a community or a place where people could grab some scripting. Maybe they could reach into Citrix or F5 load balancer APIs. Also, if you have a host go wrong or you need to put one in maintenance in an emergency situation, especially on the source side, it can require you to fix Zerto and redeploy vRAs or redeploy the little appliances to the host that they're going to be on. Also, depending on what resources it has available, storage or vSphere-wise, I'd like to see it able to balance itself out within the virtual environment, with its storage usage on the destination side. I've only run into these things briefly, so I can't speak about them at the deepest technical level, but I have noticed that they're not as perfect as they could be.

I would like the ability to monitor the performance of some specific components. Right now we're having an issue with local and remote replications with some of the VPGs. Being able to look at individual VPG performance would be helpful. Another thing that would help would be a recommender, or some type of tool that says, "Hey, you're not conforming to best practices." It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on. Another area for improvement is alerts. We're getting so much noise right now in the 8.5 version. The problem is that we don't know which are the ones we need to act on. We don't know which ones are severe versus those that are informational or notice or debug. They have told us that when we upgrade to version 9 we'll be able to tune some of the alerts. That type of alert tuning, where we can get just the emergency and error alerts, would be helpful, while not necessarily tuning out the informational or notice or debug alerts. If alerts could be channeled to a syslog server where we could filter and see which alerts are the priority that would be an improvement. We have a network operation center and for us to operationalize this tool with them, we have to be able to deliver each alert along with an action plan for it. That way they can take the appropriate action if Zerto has some type of error. It would help if the alerts didn't just fall on our storage and data protection team. If we could transfer some knowledge and have other level-one teams look at some of the more basic Zerto alerts and try to resolve them, that would help.
The only issue I've ever had is that I wish that Zerto would work more closely with VMware. There have been a few times that Zerto has released an update but it wasn't supported with that version of VMware. I would like them to coordinate their updates with VMware's updates.

It took me a little bit of time to get used to Zerto's terminology and to relate it back to how you do a backup traditionally. It was a little different. It took a little while to understand what a VPG is and what it does. That's an area that they could probably improve on a little, making the documentation easier to understand.

I know that Zerto can definitely improve some functionalities. I know some of the cloud pieces probably enable that. At the moment, it's doing what we want for us, and what it's doing for us right now is plenty. I can't say there's any improvement that I can see that needs to be done at the moment. I'm not sure if it has throttling, meaning, what's going over the wire and how we can throttle that to reduce the amount of data that's going across the bandwidth. I can't remember if that's something that's in this product. It might be in the more recent version.

We did look at the long-term retention backup feature of Zerto a few years ago, and at that time, it was limited. I can't say what it is right now, but at the time, its functionality was limited in terms of basically where we could save it and how we could save it. Offsite air gapping our backups is important to us to help protect against ransomware, and at the time, it couldn't do that. That would be one area that would be important before we consider using the long-term retention again. I haven't looked at it recently, and they may have addressed this in the meantime, but if not, this would be an area of improvement.

The reporting could be improved in terms of the reports that you can show to auditors to prove that you have done the testing. I provide the reports that it generates now but, it would be great if, at the end of a DR test, it would generate a report of everything that Zerto did. This would include details like what systems were up. Currently, that's not how the report reads. You would have to be an IT person to read the current reports that it produces. I would like for them to be the type of reports that I can put in front of an auditor or the president of our firm that would make sense to them, without me having to interpret and explain the results.

There are still some pieces in testing that aren't automated. There are still some built-in scripts or workflows I wish Zerto would do out-of-the-box, versus having to PowerShell or have a vendor create it, or create it myself. We haven't done a full failback yet of production so I couldn't really say. The failover process is a lot of manual steps, but Zerto is a mechanism that gets the data there. In that aspect, it does what it's supposed to do. But I wish they would expand on their out-of-the-box functionality for the VM. When you fail it over, there are DNS and SQL changes and there are reboots. There are some things I wish that Zerto would facilitate with a checkbox that would do some of these things for me versus having to PowerShell it and put the scripts in a certain place and have support run it. I want it more automated if possible. The issue I have with ransomware is if I don't know I have ransomware in all my recovery points, and if it goes three months, I wish Zerto somehow either bought a company or could tell me that we're infected with ransomware. If I don't know how ransomware and everything gets encrypted, there's nothing to restore back to if all my recovery points have been corrupted. So I wish Zerto somehow had a mechanism to alert me of suspicious activity. We have a Trend product that does that for us. We can get alerts of things that Trend finds, but it's always nice to have layers for your security. We have alternatives, but it would be nice if Zerto had a mechanism to alert me as well. Alerting has also been a pain but it was supposed to be fixed in the newer version and that's. I would like to have more granular alerts.

Previously, our main need for Zerto was actually database cluster servers running fairly old software, SQL 2008 on Microsoft Windows clusters with none of the advanced SQL clustering functionality. Our environment is all virtualized. The way we had to present the storage to our host machines in VMware was via raw device mapping (RDM). Technically, Zerto can do that, but not very well. We have gone to some different methods for our databases, which don't actually use or rely on Zerto because the solution wasn't that functional with RDMs. This is an old, antiquated technology that we are currently moving off of. I can't really blame them, but it definitely is something they thought they could do better than they could in practice. They had a bug recently that has come up and caused some issues. They currently have a bug in their production versions that prevents their product from functioning in some scenarios, and we have hit a few of those scenarios. Aside from that, when it is not hitting a bug, and if we're not trying to use it for our old-style, old-school databases, it functions incredibly well.

We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking.

The long-term recovery is a little bit weak in its granularity. Veeam is definitely superior in that aspect, as it's able to provide a granular view of files and databases, et cetera. However, it just kind of depends on what a business' recovery strategy is. From our business perspective, it's really not impactful to us because our recovery strategy is not based on individual files. But, I could definitely see it being a challenge if there is a very large instance of individual files, as a subset, that need to be recovered. I think that if somebody has terabytes of data then Zerto will recover it faster but navigating through the file explorer to get to files is not as easy with Zerto. One thing I don't like about the product, and I know this is where their claim to fame is, but whenever I have a VPG that has multiple virtual machines in it, and one virtual machine falls behind, it'll pause replication on everything else in that job until the one server catches up. The goal is to keep symmetric replication processing going, so the strategy makes sense, but for our business model, that doesn't really work and it has created a challenge where I have to manage each VM individually. It means that instead of having one job that would cover multiple servers, I just have one job to one server, which allows me to manage them individually.
Zerto is used for disaster recovery, business continuity, data migration, and ransomware recovery, providing continuous data protection and near real-time replication. Valued for ease of use, efficient failover processes, and versatile integration, it enhances organizational efficiency, reduces errors, and boosts productivity.
Regarding user collaboration during the data migration process, it falls more or less on the IT side of things to ensure that the customer's experience is optimal. With HPE Zerto Software in a different environment, once things are set up correctly from a networking perspective, we can spin up almost anything in the environment to match what the customer's experience was inside their home environment. If they use a Cisco firewall or Palo Alto firewall, we could put a Palo Alto firewall in the disaster recovery site, which gives them the ability to use, for instance, VPN. If they connect via VPN, they can use that exact same VPN login information to get into their new environment that sits somewhere else. This cuts down the disruption time of how long it takes for someone to migrate a firewall physically, and we could kind of do a virtual option for that as well. HPE Zerto Software opens the door for more virtual options for clients who may not have the ability to do it physically. As time goes on and new operating systems come out, HPE Zerto Software is releasing updates relatively often. What I find is that we are working in an environment where not every customer is updating every day to the latest version of, for instance, the latest hypervisor version or the latest operating system. The one thing that I would like to get improved is more legacy support for customers. Once we go past a certain version in HPE Zerto Software, it does not support certain versions. For us, many of our customer workloads are VMware based. VMware has a functionality where they do hardware versions and have their own sets of hardware versions. Many clients, once they update their environment, will update and create servers based on their brand new environment that is not necessarily supported by HPE Zerto Software right then. HPE Zerto Software, while being agnostic, will copy that data, but the hardware version for that new VM may not be supported. Because we use it in a cloud-based platform and we are doing multiple users, we cannot just upgrade one part of it because then it will affect all of these other customers. I am not sure what the right phrasing would be to describe what they need to do, but it would be more support of older systems as well as having a way to manage those persons that may be a little bit trigger-happy when it comes to updating, so we do not have to do updates across the whole entire board in order to just appease one client. We try our best to keep the client to the point where they do not do this type of thing, but we only could do so much.
There are few areas for improvement that are mostly technical. It has limited support mostly for VMware environments; they are trying to reduce support for Hyper-V and now bring it back, but it's not working as easy with VMWARE. There is a problem where you need to perform a full sweep to back up and sync a VM from the beginning, which occurs in some scenrios. There are times you need to restart synchronization from the start, which is a heavy operation without clear reasoning, consuming a lot of resources.
The main improvements needed are related to historical data comparison and analytics, and the challenges involve reliance on other software and cross-checking logs. If we could have an end-to-end DR solution in one environment, it would be much easier without relying on multiple tools. The biggest area for improvement in HPE Zerto Software is probably in historical data comparison and enhanced analytics. Future features should reduce reliance on cross-checking logs and other solutions.
I think HPE Zerto Software is excellent, and I don't see any issues with it, so I don't know if anything needs to be improved. I don't have any suggestions for additional features I would to see included in the next release of HPE Zerto Software.
I don't know how HPE Zerto Software can be improved; I think it's pretty great. If it can recover VMs or infrastructure into public clouds or vice versa, that would be awesome. One potential improvement for the future would be competitive pricing with Veeam.
To improve HPE Zerto Software, I would suggest that the upgrade process is a little bit average and challenging at the moment, rather than necessarily adding features.
I don't have any recommendations regarding how HPE Zerto Software can be improved or what additional features should be included in the next release.
I cannot think of any ways HPE Zerto Software needs improvement, as I have used it at a previous company as well, and it is a reputably reliable platform.
I hesitate to offer improvements for HPE Zerto Software since I appreciate it so much; the user interface is good, and the actual data under the hood is good. It keeps working, it's fast. However, it could benefit from tighter integration with VMware. They have a head start on proving that the new version will work. When cybersecurity events happen and we have a new release that we need to deploy quickly, they have a 90-day window to remediate that, but I need to deploy it before them, and I can't.
I don't have any idea of areas fro improvement.
I definitely would like to see the continuation of the migration capability to Hyper-V included in the next release of HPE Zerto Software, as well as adding migration capabilities to other hypervisors, such as Nutanix Acropolis.
When failing over virtual machines (VMs), where VLANs aren't spanned across geographical data centers, it's essential to change the IP address of replicated VMs. The mechanism used to control and configure this process could be improved for customers with restrictions on DHCP usage. Additionally, there are nuances to consider when dealing with Linux systems.
The HPE Zerto Software can be improved with more visibility. It's really hard to find out what stores and what drives I'm using, and then to translate that over to the cloud solution.
We encountered some issues with HPE Zerto Software. The main concern involves the Delta Sync that triggers when changing the recovery direction. For large virtual machines of several terabytes, this process can take considerable time. As a bank, we are required by regulators to run regular DRC scenario testing for one week from the DRC site. When changing replication, the Delta Sync takes approximately six hours for six terabyte virtual machines. During this time, the virtual machine is inaccessible. If another major issue arose requiring us to return to the PDC, we would have to wait six hours for the Delta Sync to complete, which would result in a test failure. This represents our biggest challenge.
HPE Zerto Software can be improved by allowing a system inside my makeshift vault to reach out to the other system and pull backups inside, which would let me punch fewer holes. Currently, my understanding is you have to have two systems that are interconnected. Based on how I've built it, if I could have a system inside my makeshift vault reach out to the other system, that would be more secure. Right now, both systems have to talk to work. We've completely rebuilt our infrastructure inside, including firewalls and everything, inside a basic vault. It has the same concept. For that system to replicate, we have to have holes in the firewall for the outside system to reach in to connect to the HPE Zerto Software inside. A lot of the wording isn't very clear. If you don't know what you're looking at, it just oesn't make sense when you are setting it up.
HPE Zerto Software can be improved, however, I will have my other team members address that question. The ease of setup can be improved in the next release of HPE Zerto Software. The initial setup of the DNS environments and backup environment took us time to implement, and if the process was wizard-driven, that would have been really beneficial.
That could be an area where HPE Zerto Software could improve; it could be easier to use. The setup and maintenance of it moving forward is where I had a lot of issues. When I compare it to hardware that can also do the same thing, it lacks its luster for the simple reason that the hardware is built to do it.HPE Zerto Software didn't help to reduce my organization's DR testing; I was shocked by it since whenever I actually performed the DR test, it took my environments down.
I want to hear more about the Commvault integration that was announced, as I don't know what's included in that one yet.
An improvement I would like to see in HPE Zerto Software is the ability to start protecting bare-metal configurations, as today it only handles virtualized workloads. I would love to see some progress in bare-metal protection. Several bare-metal use cases also need similar RTO, RPO, and business criticality thinking, which would be fantastic if HPE Zerto Software ventures into the bare-metal space.
To improve HPE Zerto Software, it would be helpful to make it more affordable. In the next release, I would like to see additional interfaces with HPE, as I talked to HPE about some storage solutions and know there is something in the works possibly between HPE Zerto Software and HPE that would make my life easier.
As for improvements to the HPE Zerto Software, I can't really think of anything as we have a very specific use case for it and don't use all the functionality. Potentially integration into some of our other solutions would be beneficial, as we're using ServiceNow as a platform. If we could integrate our AIOps solutions and incident management capabilities within HPE Zerto Software, that would be beneficial, as it would enable us to automatically bring the DR site online when a major incident is detected, eliminating human involvement and making the process quicker than manual decision-making.
The only thing I could suggest for HPE Zerto Software would be better support for detached drives in a clustered environment, as it's currently not supported very well unless everything's running on a virtualized VMDK file. If it's detached an iSCSI drive, it doesn't work, so that would be about the only thing I would suggest.
My only suggestion for how HPE Zerto Software could be improved would be to integrate with other virtualization platforms, as many organizations are moving off of VMware, so having options there would be beneficial.
I'm unsure of what can be improved.
Outside of disaster recovery, we are looking to leverage HPE Zerto Software for converting from VMware loads to Hyper-V. We have been doing testing and have concerns that support for Hyper-V ending with 9.7. Now that Broadcom has created an opportunity in the market, we're looking at Hyper-V. We also have a Microsoft ELA. Continuing support on Hyper-V is something we would want to explore.
HPE Zerto Software can be improved for automation. I would appreciate more integration with vCenter in the next release and how we can protect our production servers and automatically get them put into a VPG. That's what I'm working with right now to try to build automation for it. If HPE Zerto Software has it built-in where we're going to vCenter and you click on it, it will build the VPG and indicate configuration requirements, that would be amazing.
When we did our test this year with HPE Zerto Software, we had some failures that we weren't expecting. The challenge was realizing there was data corruption, and fortunately we found it before we committed the failover, so we could fail back. We could resync it, and we weren't in an actual disaster. If there's any way to validate that data on the recovery site without having to manually go in and do failover testing and try to validate, that would be a feature that would be really nice. We're not sure why we had some corruption, however, we did the resync and it seemed to bring it back up and fix the problem. That's probably the biggest area I'd ask about - some way of validating the recovery sites in an automated fashion.
The migration part of the HPE Zerto Software is already there. In terms of improvement, we have VMware and Nutanix, and we are looking for solutions to perform migration between these two setups to save costs.
HPE Zerto Software could be improved by including everything in the same package. If I had to suggest an improvement, I would want everything in the same package, such as HPE Zerto Software and Veeam together. Currently, I have to administer them separately, which can be more complicated for the infrastructure team. That would be beneficial. Regarding critical features, I don't see anything more than what HPE Zerto Software is already providing.
The HPE Zerto Software could be improved by including the ability to use FIDO keys or some kind of hard token for local accounts, not just a straight password or an external MFA, but a physical token. Additionally, I'd appreciate the ability for direct-attached storage, not just Nimble storage, VNF, both volumes. I would also prefer to have some way to scan inside the vault of datastores that are already there.
HPE Zerto Software could be improved in the future with easier upgrades. I am not aware of any additional features I would like to see included in the next release.
HPE Zerto Software could evolve to where, instead of me having to push a button, it can detect disasters on the fly and automate disaster detection.
With the current updates primarily on the Azure side of it, documentation could be improved. That's not necessarily Zerto's problem since Azure is constantly changing things; Zerto will put something out, but Azure then will change it, and sometimes it's hard to follow that documentation. HPE Zerto Software can be improved by keeping up on top of the Azure changes happening there, trying to smooth that process out, because there are many steps that you have to take in Azure, and that's not necessarily HPE's fault, it's just how Azure functions.
I run a very dense VM-to-host ratio in my environment. Whenever maintenance is being performed on a host, all the VMs on that host have to be powered down and/or moved off to complete that maintenance cycle. It is frustrating when the protection of VMs doesn't get relocated to another host before the replication appliance powers down. It sometimes works great, but if the host has a lot of VMs on it, there may not always be enough time to relocate all of the VMs from a protection group standpoint to other hosts before the replication appliance that Zerto uses to manage that powers itself down. In such a case, you are breaking replication for the duration of that maintenance, and that can cause some support issues when you bring it back online, where you have to go in and manually recover it. I know they added improvements over the years. It's not as bad as it used to be, but at times, I still end up breaking replication when I do maintenance on my hosts.
Zerto works great. The pricing could always be lower.
Its pricing could be better. Also, Zerto needs to improve its reporting capabilities and provide better dashboards. A number of times, I had to contact Zerto for more reports. They are very customer-friendly. They helped us and gave us some customized reports, but its reporting capabilities could be better.
Near-synchronous replication has some trade-offs. With near-synchronous replication, we get almost all the information up to date at the destination site, but the trade-off is that sometimes that could take a lot of CPU cycles, network bandwidth, and troubleshooting. A few versions back with Zerto, there were some bugs in the software that were causing constant replication back and forth that was driving a lot of network bandwidth utilization over the network, and we did not know why until we found out it was a bug. It depends on what your business or application really requires. If it requires near-synchronous, you have to enable that. However, if Zerto can make it easier or have a smaller footprint by sending larger payloads or having network compression, it will be a little bit easier. On wide area networks and local area networks, that would definitely be preferred. We have had some issues running Linux virtual machines on the new version. There were some issues with virtual replication adapters on Cisco UCS hosts running VMware vCenter 8. There were several things we had to do with installation and getting the replication adapters to work. Integration with Keycloak for Active Directory authentication using new Linux VMs was challenging, but it is now functioning well.
The biggest area for improvement is the technical support side. Although it has improved somewhat, after the HPE acquisition, it became apparent that level-one technical support was moved to groups unfamiliar with the Zerto product. As experienced users of Zerto, when we need to open a ticket, dealing with level-one technical support can be tough. We often need to escalate immediately due to our internal skill set surpassing level-one support capabilities. That is the biggest complaint we have with Zerto.
When it comes to failover tests, we would like to be able to take that extra step to shut things down and see what it looks like at the other site versus just doing it in a virtual environment. That is one thing I would push back on them. I would like the ability to perform actual failovers more easily compared to our current process. In the event of an issue, we can switch and bring back servers smoothly, but when we do the tests, currently, Zerto's test failovers are virtual. We cannot get end users to come access those systems. I would like to be able to do a test where we failover and rebuild the network connections so that end-users can hit that center or server and test. Improving testing capabilities would be advantageous. When it comes to deployment, one improvement could be being able to visually see virtual private groups and server names. Although the reporting is comprehensive, occasionally, people use long names that do not display fully on the monitoring page. Despite this minor issue, deployment has been easy, and we rarely need support.
Some of the cloud instructions around VNets and peering of networks could be clearer with some best-case examples. It is more complicated once you move into the cloud than running it on-premises. Actually doing these things is quite easy in the cloud and with Azure, but understanding how it fits in my environment can be quite a head-scratcher at times.
I cannot think of any features that Zerto does not have. They probably have a lot of features that I do not even use. I am primarily interested in Zerto as a backup and recovery mechanism, and it does a phenomenal job of that. It is an enterprise-grade tool, and enterprise-grade tools tend to be complex. They can be a little difficult to use at first until you learn them. It is not reasonable to suggest making it easier to use because it is an enterprise-grade tool, and it is very robust. Therefore, it is not going to be easy to use. I just have to spend the time to learn it and become good at it. I am very pleased with it as is, but the ease of use of the restoration utility could be challenging initially.
I would suggest improving automatic updates. Their software requires updating level by level to keep it current. I was unaware that I was several versions behind, so I needed assistance to guide me to the current version.
The main issue with Zerto is its user interface, which lacks flexibility and presents a steep learning curve. To improve usability, the UI should be simplified and streamlined, making it more accessible to technical and non-technical users. Additionally, the UI should be better aligned with the platform's various options and features, ensuring a more intuitive and efficient user experience.
Zerto's pricing model is cost-prohibitive for small—to medium-sized businesses. Its structure limits affordability to approximately five to ten virtual machines. To increase accessibility for small and medium businesses, Zerto should consider a competitive pricing strategy, possibly including subscription-based licensing options. This would enable more organizations to utilize Zerto's services. I want Zerto to add support for Proxmox.
Zerto could improve by offering more flexible pricing models, especially for startups. In the Indian context, cost is a concern for many businesses, and a pay-as-you-go model would be beneficial. Additionally, more cloud support is needed beyond the major providers like AWS and Azure, such as support for Alibaba and Oracle Cloud.
While Zerto provides good service, I find the pricing to be high and believe there is room for improvement. I would like to see Zerto implement a pay-as-you-go model. While Zerto offers scalability, its implementation can be more challenging in larger organizations, indicating room for improvement in its scalability features.
They have moved to appliances, and the configuration of appliances is a bit complicated. The appliance is is very complicated to configure by proxy as they move everything to containers, and each container needs to be configured. It's a little bit complicated.
The tool must improve its long-term storage cloud strategy, making it more seamless and improving the solution's downtime features.
Zerto's pricing structure could be more competitive to better suit the needs of a wider range of businesses. The setup process could be simpler. A more streamlined installation would improve the user experience. Zerto's long-term data storage capabilities, specifically how long data can be retained and managed, could benefit from further development.
Zerto can improve by offering bare metal recovery for our physical infrastructure.
While Zerto's current version supports VMware environments, I'd like the added flexibility of using Hypervisors as well. Although previous Zerto versions offered this functionality, it seems to be missing in the latest iteration.
The recovery processes of large datasets in the Cloud have room for improvement. The backup functionality can be improved.
The primary concern expressed by all server users is the lack of robust integration features. While Zerto offers some integration capabilities, the smooth and efficient data flow between portals remains a significant challenge. The support and technical teams know this issue and actively seek user feedback, but progress has been slow. The current process, involving multiple platforms and a database management system bottleneck, is time-consuming and inefficient. Additionally, while reporting and dashboard features exist, real-time reporting and mobile functionality require improvement. The user interface could be more intuitive and user-friendly. Customization, a critical requirement for government clients, is another concern. Implementing requested changes is often time-consuming and expensive, hindering adaptability. Addressing these integration, reporting, user experience, and customization issues is essential for improving customer satisfaction and retention. Currently, Zerto only offers an annual subscription, but it would be beneficial to provide quarterly and semi-annual subscriptions to help retain clients.
While going in, we were looking at the backup tool so that we had a DR tool and a backup tool, but they stopped developing their backup solution built into it. That was a bummer for us, so now, we have a DR solution, and we have a backup solution. For the actual application itself, we have put in our request for certain features, and so far, they seem to be adding those features. In their latest one going to version 10, they did an appliance, which we had asked about 6 years ago. It is great to see that they are doing an appliance. There would be even more savings for us now because we do not have to pay licensing for a Windows VM.
One thing I would like to see in their roadmap is introducing long-term storage in the cloud such as Azure or AWS. They can make it more seamless. The downtime features can also be improved.
Zerto integrates with vCloud Director to protect workloads deployed there. However, it would be beneficial if Zerto also offered integration with other cloud management platforms, such as VMware Aria Automation. For example, Site Recovery Manager recently introduced integration with VMware Aria Automation, allowing the protection of workloads deployed through Aria Automation. This functionality, including site recovery management, is currently not available in Zerto. Zerto's strength seems to lie specifically in its VMware capabilities, which could be an area for improvement. Another point to consider is the potential for Zerto drivers to cause issues in ESXi environments. In some cases, users have reported problems and discovered that the Zerto drivers are not verified by VMware. While HPE is a technical alliance partner for Zerto, improved collaboration between VMware and Zerto regarding driver validation would be valuable. This information seems to be missing at the moment. We are currently in touch with our technical account manager to clarify this.
It would be great if Zerto could automate replication more.
Zerto's solution could benefit from additional security features, such as malware scanning tools at the recovery site.
The product could benefit from improvements in automation, specifically in the area of failovers. Currently, the process is largely manual, and introducing automated failovers after a certain time threshold would enhance efficiency and responsiveness. Automated failovers can reduce the dependency on manual intervention, allowing for quicker and more proactive responses to disruptions. In the next release, the inclusion of scheduled or automated failovers would be a valuable addition. This feature would empower organizations to set predefined parameters and triggers for failovers, ensuring a timely and automated response to potential issues. It not only streamlines operations but also adds an extra layer of reliability to the overall disaster recovery strategy.
There should be more comprehensive cyber recovery capabilities.
The replication layer can probably be improved.
It would be nice if Zerto offered OVFs, which are custom-built VMs that you can install on your virtualized environment. At the moment, I have the Zerto sitting on two custom-built Windows servers, which creates a lot of overhead. I'm waiting for them to create an OVF file, which is a built and hardened version of their Zerto server that I can just install wherever with a couple of mouse clicks.
I would like to be able to replicate one to multiple without having to recreate every VPG. That would save us a lot of time. When we add a site or move our DR to a different site, I have to recreate everything from scratch. So, it'd be cool to be able to just repoint an existing VPG to a new site without having to recreate everything.
One issue we've been having with Zerto lately is the ability to go into maintenance mode during vSphere upgrades. It doesn't have the hook into the lifecycle manager of the bump. During vCenter or ESXi upgrades, it causes VCF to fail its pre-checks because the machine doesn't power off and go into maintenance mode. It's been an issue since version 7.5 and it's impacting a basic automation function in vSphere.
There's a mandatory VMware version, so we need to update our VMs in order to access our data. Zerto should work with all VMware versions.
Previously, it was not compatible with the public clouds. However, now that it is, it's helped a lot. One of the most challenging aspects in migrating items from private to public. We'd like to be able to migrate data without its operating system or any other functionality and without having to go through a virtual machine or server.
When we migrated to a new virtual infrastructure, we had to set up Zerto all over again which took a long time. It would be nice if Zerto had some sort of migration tool where you could migrate all of your virtual machines to a new infrastructure without having to set up Zerto all over again.
Zerto could improve its reporting capabilities. That's lacking. The alerting capabilities are lacking as well, partly due to the fact that there's no way to trim down the alert fatigue if there are failures within the application. It will send out alerts consistently instead of spreading the alert times every 30 minutes, hour, et cetera.
Now, everything is moving to the cloud and many modern app solutions are based on virtualization and cloud, however, for situations where Unix platforms are used, we'd like them to be able to support that.
It's a great product. There are a lot of features that it has that we don't use since we are on prem. We strictly use it for DR between our data centers. There are a lot of cloud plugins that they have that we don't use. Our use case is limited. It does everything we need it to.
The post-configuration part could be improved. For example, it would be super helpful to have the ability to modify DNS. Once the migration is done, we want to do some more modifications to the endpoint.
Right now, if you have an error, it creates a link that takes you to a website to review information about the problem. It would be nice if Zerto could give you information within the app instead of referring you to a web application.
I would like Zerto to add support for VMware's lifecycle manager.
Maybe the reporting for the failover test could be a little better.
Zerto generates many false positive alerts, which is annoying. I still have thousands of alerts in my inbox, and those are false alerts. When I check there's actually no problem.
Their data backup and restore have some ways to go. We looked at replacing our traditional backup system with Zerto and found it was lacking about a year ago. We have Commvault, which is very customizable and feature-rich in comparison. Their offering needs to be more robust.
I don't feel like we're a big enough customer to warrant being called every week or every month but it would be good to get a little bit more contact with a salesperson or engineer group. Our account executive is very good. He's done a great job, but it was hard for him to tie down an engineer. It was a little bit of a strain to get somebody lined up to show us what version 10 was about. Once we got it, it was perfect. It would be nice if it could be easier to do that. They have VPGs and VRAs. The management of that when trying to do a VMware upgrade can get a little finicky. You have to bring nodes or hosts up and down where the VRAs are running on the hosts. Sometimes the VRAs won't come back up or they may not respond. So when you're done doing your work, it could be that you have fifteen servers that are not replicating. So you'll have to stop, delete, manually remove what you need to do, recreate the VRA, and that's easy enough but you have to go through and do that, and then resync. That's part of IT. They are a little finicky. Version 9.7 has been a little easier to work with, and it integrates with VMware a lot easier. It shuts down the VRAs. The VRAs are finicky about how they get shut down.
Zerto could be easier to configure when we need to perform data testing and establish network connectivity outside of the isolated environment. We encounter situations where there is a desire to test a printer during disaster recovery testing. However, due to the presence of an isolated environment, doing so can result in complex configurations. Zerto needs to improve its support for VMware Lifecycle Manager. This creates a problem with VMware's ability to automate the complete VMware stack upgrade.
One concern we have is the speed at which Zerto maintains compatibility with VMware and different versions of VMware. We are specifically worried about potentially major security issues with our current ESXi version and whether upgrading it would cause any problems or compatibility issues with the Zerto version we are using. It is crucial for Zerto to collaborate closely with VMware in order to promptly test updates.
There should be an automatic installation in a cluster. When I add a virtual client or ESX source to the cluster, it should automatically install that. There should be automatic installation. Currently, I have to do that manually. They can give us a few training classes.
You can use Zerto as a backup product, but in the discussions that I have had with them about the product, they don't really sell or talk about that feature as much. So I would be interested in improvements related to using it as a backup. If I could consolidate and use Zerto for disaster recovery as well as everyday backup and restore for situations where I need to recover something, that would be helpful. It has some of that functionality, but it's not something they promote a lot. They should point out the benefits of using Zerto as a backup and recovery product instead of just a DR product. With Cohesity, we keep a limited amount of backups, about 14 days. That way, we can recover an individual server within the same site or we can restore data or databases that we need, in a non-DR way. We use it for typical day-to-day backup and restore. If we could use Zerto in a similar fashion for everyday backup and recovery scenarios, that would be another area where we could consolidate into a single application.
They just came out with improvements for ransomware protection last week. I haven't used them yet but, overall, security and preventing ransomware is really a hot topic these days. I would like to see it detect when the ransomware occurs and provide more information on it.
I turned in a ticket a while back when I found a glitch within Zerto. When building out a VPG and doing the machine types within Azure, they were not coming across correctly. It would say it had a CPU and memory of a specific type, but it was not accurate. When I sent that ticket in, the support manager said that it hadn't been found before, but that my report was accurate and that it was a bug, and that they were working on it. But I've been very pleased with the updates that they put out and the service. I don't have a lot of negative things to say about Zerto.
The only challenge we have encountered is with rotating passwords on our VMware nodes. With secure boot enabled, which is the case for newer systems, it is not easy to rotate passwords and we would have to reinstall the VRAs. This is not ideal, especially when our security team wants to rotate them weekly. Aside from that, everything has gone smoothly. The updates are easy and it does not hinder us when updating the VMware. The only issue is that we have to wait three months after a major release. This lessens the complexity of the update of the software itself. Other than that, there is no issue and it does not hinder us from running different versions of VMware.
It would be beneficial if we could gain insight into DNS record reporting from the DR side, however, this is not a realistic expectation due to the fact that different companies use different hardware and different methods of DNS management. It would be advantageous if Zerto had plugins for Infoblox, Cisco, or load balancers, as this would enable us to better manage those records. Unfortunately, this is not a realistic expectation as these products are usually managed by the middleware or a network team, which has no relation to their application.
Zerto's connectivity with automation platforms could be improved. For example, vCenter can use a VMware-developed tool called Site Recovery Manager. That can be integrated with automation platforms such as Terraform, Ansible, Chef, or Puppet, to perform automated, self-sufficient recoveries to essentially avoid any downtime. To my knowledge, Zerto does not have integration with those platforms. Zerto does have an API, but a lot of those automation platforms have prebuilt runbooks to enable that process, whereas Zerto does not.
Zerto's price has room for improvement.
Recently, I started to try to deploy vVols instead of VMFS volumes in my VMware environment and I did encounter an incompatibility. It seems that for Zerto volumes to be protected, there's some sort of limitation with drives having to be either thick-provisioned or thin-provisioned, I forget which. But there's some sort of inherent limitation that causes an incompatibility with vVols and VMware. That has to be overcome somehow. It has to be flexible enough to be able to do its thing. And for an additional feature, and I'm not sure if this is already in the works, I would like to see improvement on the Zerto Virtual Replication appliances, so that they are a little bit more streamlined as opposed to now where they just span multiple ZVR appliances like there were gremlins. We have our three main ZVR appliances, each one of them associated with one of the hosts, but as this thing grows it just spawns unlimited numbers of additional ZVR appliances and you end up with a bunch so that you can't really tell which is which. Better management of those ZVR appliances would help, if you have to vMotion them off of something. If you want to migrate a ZVR appliance from one storage to another, you can't really tell what's what and there are multiple pieces related to this ZVR appliance. I would like to see that cleaned up a little bit with better management features for ZVR appliance maintenance overall.
Improvements in stability would be welcome; there are some software bugs that can affect RPOs. We want more of a guarantee that we won't lose any of our backups, even in the event of a disaster. The platform measures the write speed of storage devices and gives an alert on the VPG if there is latency, but the nature of the alert suggests the solution isn't meeting the SLA. However, this shouldn't affect the health status of the backup. It should provide an express report that we should enhance our hardware rather than express latency as a threat to the backup capability.
I want to have an OVF or some local deployment where I can deploy the ZVRA rather than having to push it from the console. Some of our smaller remote sites have relatively poor bandwidth, and they can't keep up with the constant deployment stream from our center console, meaning we have to find some creative hours to get around the bandwidth bottlenecks. If I could push out a small install file, install it locally, and then reach back to the console, that would be excellent.
The IT could be better; we have sectioned areas and databases for iOS, Windows, and Linux. Because the solution is centralized, each computer has the VMs from every section running. The solution is very expensive.
We would love to have a native management pack for vROps and to be able to view a dashboard and metrics for BPGs within vROps. We would like to have a single view for monitoring and provide customers with dashboards so they can see their own BPGs. We would also like to have a native plugin for VRA built by either VMware or Zerto. That way there's actual support for it and we're not on the hook for trying to figure out what happened if it breaks.
The alerting could be fine-tuned and improved. It does a lot of alerts, but it's a little bit cumbersome to modify them. It could be cheaper as well.
The only thing I really don't like about Zerto is that the ZVM has to be a Windows server. I can spin up any OBA template whenever I want to, but if it has an OS that's tied to it, then I have to involve the OS team from my company. That drives me crazy.
Zerto is more of a set-and-forget-it type of solution. As long as the replication is continuous and there are no issues, I don't touch Zerto. We don't have a lot of workload that needs to be up. We just have our web server and our applications here. Those are two main servers that we get up and running in a disaster-recovery type situation. I can't give any area of improvement from a real-world experience because we haven't had that issue, but from testing, Zerto has been working great. It is not something that goes beyond what our use case is for. When it comes to a solution, one of the things the management wants is to standardize platforms. That's why when Rubrik came out with their solution, they wanted to look at it. For instance, if you have multiple technologies, you're going to need admins to manage all those different ones. I would like Zerto to be something that fits all our needs, including the backup that Rubrik provides, but I understand that not all solutions can be that way. When I started working here, my predecessor who was managing Zerto had no documentation. So, I had to take over. No one else knew how to manage Zerto. So, there is just that type of learning process. That's why management wants to standardize on one solution so that it is easier to cross-train, but that's not Zerto's part. It just happens to be our environment and our management style. Zerto as a solution has been great for us.
More user support would be best for me because I'm not in the product all the time. So, having strong support is probably the most important decision on any products that we buy. The price is another thing that they definitely need to work on unless it has changed. I purchased mine a while back.
Zerto added the backup feature, but it's not quite up to speed yet when you compare it with the backup capabilities of other solutions out there.
This solution could be improved if it met all the requirements that we look for including supporting multiple operating systems. We would prefer to use one solution for DR and backup.
This solution could be improved by including some sort of compression or de-duplication for the same type of files.
The licensing is confusing and complicated.
The biggest improvement would be exporting VPGs and a configuration of VPGs, as well as increasing or improving their IP customization rule set.
The time between releases is too long. Zerto doesn't seem to really keep up with the products with which they need to be compatible. For instance, the 9.5 updates 3 took about 90 days to come out after the latest version of vCenter 7.0 update 3 was released. We were facing a vulnerability, so we had to choose between patching our vCenter to address that vulnerability, which would break the Zerto operability, or leaving it as is with a potential vulnerability. That was really the main issue we ever faced with Zerto.
There's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for. With the orchestration part of the failover, with our DR and our primary sites, the IP addresses are almost identical. The only difference is one octet. With SRM, we could say during a failover change. With Zerto, we keep hearing that it's coming, but we haven't received it yet. It's a feature that would be very beneficial. It would reduce the time a little bit more.
We're an NSX-T shop, and if I could get an NSX-T integration where it could manage the networks a little tighter, that would be an improvement. The other improvement is working with storage vendors, like Pure Storage for the synchronization of the data similar to what SRM does. Using Zerto for the orchestration, and the hardware vendor for the replication would be beneficial.
The VPG model has caused a bit of a concern. We are considering using Zerto to replace Site Recovery Manager. SRM is very easy when we have entire data stores being replicated. We don't have to make any decisions when it comes to groupings of VMs. If we move to Zerto, which we are considering, we will have to work closely with our applications teams to create VPGs and determine how the VMs will be grouped. This will probably be beneficial in the long term, but short term it will create more work for our team. I spoke to a Zerto engineer who mentioned that we could do a VPG at the cluster level and a VPG at the datastore level. However, the one issue we've seen with VPGs is if the synchronization fails the entire VPG has to be recreated. Even though we can cover our environment at the cluster level or datastore level, that wouldn't be ideal. We really need a simpler solution for DR that will cover all of our VMs at once, instead of spending a considerable amount of time on VPG creation.
I need to get up to the latest version so I can move my journals to a particular LUN, saving them with a particular storage altogether, rather than with the virtual machine. This is not available until I upgrade, and I need to upgrade all my hypervisors. This would be something that would be nice to have if it could be used on older versions.
I would like to see the app be more like the analytics site. Right now, when you go into the analytics, you need to zoom in real tight on your browser. You get a lot more from the analytics site than you do from the app. If they made those two more similar, it would be really useful for day-to-day monitoring of your stuff. I don't like the evacuation process. The host evacuation process could be a little simpler too. It takes our maintenance a bit longer, when we are doing host maintenance, because we still need to evacuate the vRAs manually. I know they tried to make it more automatic, but it is not quite there yet.
We would like more mobile options. If we are at a restaurant or out and about in our normal daily lives, we would like to be able to interface via our mobiles.
If something happens, and we are out and about, I would like to be able to interface with it on our mobile phones. That would be great.
If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens. The other thing that I've run into lately is that when I've done a whole bunch of upgrades to systems, so they're offline, they get stuck in a pending state. You can never get them out so you have to delete and start all over again. It would be nice if they could make it a little simpler to figure out what's wrong.
This solution could be improved by being more cloud agnostic.
We had a situation where we had to relicense VMs once they were moved over. We later found out that that feature is built-in, but it's not easy to find. The way it's done is that you have to go to the target site to turn it on. If that were explained a little bit better up front, that would be helpful.
The backup end of this solution could be improved. We tried using it as a full backup solution and it took way too long to complete at least one backup. We tried it once and didn't try again. I'm not sure if they've improved that since then but we actually went in a different direction for backups.
The overall management plan could improve. If something happens with the VM on the vSphere side, the error codes are pretty weak. If there was a way to click on something within the UI that takes us to a support page or article, that would be very beneficial.
There has been one pain point that we have run into. We wanted to shut down the dev environment to focus on the prod environment. We couldn't find any option in Zerto to do that.
Right now, our production environment runs on-premises, and we have a DR copy of everything that we run in production. However, our development runs on that hardware. In the case of a DR event, we would need to shut down development and bring up our secondary copy of production. We're hoping that Zerto is going to be the tool to help us do that.
I had to have my colleague contact technical support because we had an issue where VMs in VMware were getting blocked, and we weren't able to delete them.
Customer service and technical support need improvement.
Whenever we do a failover, there's a confirmation box that shows up later. It's a little hard to see sometimes. We'll do the failover and some preparation activities and then there's a checkbox you need to check to continue and sometimes it's small, in the corner, depending on which screen you're using. A popup to continue would be a little bit better because then you're not sitting and waiting for something and it's already there. We also had an issue with a misnamed network. They should make that a little more apparent when it's not available on the destination side. We were able to go all the way through with it, but when we did the recovery, it wasn't available. A pre-check to say, "Hey, it's not available. What network do you want to use?" would be helpful.
If we have multiple VMs in a VPG (Virtual Protected Group) and one VM is hung for DR, it holds things up. The only alternative is to create multiple VPGs. It would be nice to have one VPG where, if one VM is failing, it does not impact the overall process.
Zerto is not an API-first company, but an API-now company. A lot of the functionality that is in Zerto UI is not in the Zerto API. That is likely because it is baked in code or compiled down DLLs. Every business has to make a decision to work on something, and I don't think Zerto has committed resources to working on that part. It is a problem to do cleanup for Azure Blob Storage, recovery site storage, or whenever you remove a VM from a VPG without deleting the VPG. That needs to be improved. Doing scheduled disaster recovery connection tests, e.g., being able to migrate things up and get things working on a recovery site without needing a user to do it, would be helpful. Analytics has a 90-day window, where it keeps data. It would be nice to have on-prem storage instead of cloud storage for that so we can keep the data for longer. Unless you discover the problem within three months, you don't know that you need the data. Then, it is gone by the time you realize there is an issue. I would like to be able to offsite some data. We export our analytical data so we can keep it longer without having to script around it. It is possible right now, with the API, to script around it. However, I don't want to have to write a monthly process to export the last three months of data to a spreadsheet so I can just have it if I need it. A lot of the PowerShell documentation in some of Zerto tutorials or how-tos is a PowerShell-to-legacy sort of paradigm. It needs to be updated to at least 3, likely 5, or probably 7. It looks like it was written by someone who didn't know PowerShell, but had to learn it really fast. It does the job. If you copy and paste it, then it will work, which is something. That is way better than what a lot of people do. However, I feel like a bit more effort should be pushed towards PowerShell. I would like them to build an alerting system. I am trying to find a way to connect it to my business continuity people, so the Zerto people don't need to be pseudo-business continuity people all the time. They can just be IT people. I would like more creature comforts for the scripting engineer. It would be nice if they could expand the development community around building different APIs or API structures for Zerto.
I have had problems with vRAs. When I am trying to restart a host, sometimes the vRAs will hang. I would like it if they wouldn't migrate off or shut themselves down, then I have to manually work with it a lot of the time.
There are certain things about the user interface that could be a little bit more user-friendly. But it really depends on the audience. If we are using it as a technical tool, our team is the audience and we are able to utilize it. But if we were to pass this on to, let's say, the department users, that would become a little problematic. I'm wondering whether or not we can actually expand our offering to those department users. That may be a question.
It needs more documentation and automation features. I would like more documentation on designing an environment and network operations. On the automation side, I would like automation to clean up the environment in cases of a failed DR effort. An API interface to perform the DR exercise would also be nice.
The syncing of the replication needs improvement. My experience has been that, every once in a while, when you go to do a failover, it tells you it's not syncing. Then you have to troubleshoot and figure out why it's not fully synced up.
Zerto can improve the dashboard by making it even more simple. Right now, there's a lot on the dashboard, and it can be overwhelming. If you're an experienced user, then you'll find it easy to use, but if you're a beginner, it will take you some time.
Even though Zerto is for disaster recovery, it would be nice if it can also make backups.
It's hard to say where it could be improved. The few times I've had issues with the interface, which is, for the most part, intuitive, we have been able to take care of most issues without having to open a case. There are a couple of areas in the interface that are not very intuitive. Most of them are pretty easy, but there are a few areas in the journal and replication that, unless you've done it before, you really have no idea what to do. When I get to those points I'll reach out and ask for a little assistance or do a Google search to find the solution to the problem that we're having.
You can create a VPG and put anywhere from one to 17 servers in that group. We build them one by one. If something changes in VMware, it would be nice to be able to go in and change that VPG, having it update without messing up. When you change them now, it only applies to the copies from the points when you changed it. I wish it would purge that older data from the past. Right now, we have to build a new VPG, which is not a big deal as it is just a few screens.
It would be nice to have the option to do automatic failover, but right now the only option is manual. Zerto hasn't replaced all of our legacy backup solutions.
I would like to see some graphical improvements in Zerto's interface. There's an option to export a list of all of our servers, but the information isn't presented the way we want. We want it in a specified sequence broken down by region, etc. We can't manipulate the data when we export it. Maybe they could change it to look more like an Excel sheet, and we can customize the graphics and data. We suggested these improvements to Zerto through their portal.
I wish Zerto had better file restoration capabilities. We have not been able to use that because of the limitations of Zerto's de-duplication technology. When we used the immutable data copies feature, we had some lag in replication times, so we don't use that anymore. When there is big data movement, it tends to cause some lag.
It is very quickly developed, and new features are provided quite often. I don't have any input for improvement or a critical feature request at this moment. If anything, a lower price is always better.
There are quite a few elements in the long-term retention areas that I wish were better. The bio-level recovery indexing of backups is the area I struggle with the most. That's probably because I desire to do tasks that ordinary users wouldn't do with the solution. The standard medium to the large customer would probably never ask for anything like I ask for, so I think it's pretty good the way it is. I'm excited to see some of the new improvements coming in the 9.5 version. Some of the streamlines and how the product presents itself for some of the recovery features could be better.
In general, the solution is pretty good, but because it is geared toward simplicity, sometimes, when things go wrong, the answer is not very detailed so that things can be solved quickly. If things do go wrong, it does require a little bit deeper troubleshooting to resolve the issues. That's the only area where improvement could occur. There should be a little bit more details about if things go wrong, how to remedy them. Everything is meant to be simple. When something doesn't work, even though what you were trying to do appeared to be very simple, there are probably a lot of pieces behind the scenes. So, to be able to narrow down where in those 100 steps something went wrong can be a little tricky. When there is a failure, there should be a more detailed explanation of what the error is and how to remediate it. Currently, it's a little vague. A part of that could be because we use Zerto on top of Hyper-V. VMware still has a very large market share over Hyper-V and a lot of the information and a lot of the deployment plans are geared towards VMware. So, sometimes, there are new features that first roll out to VMware and then come to Hyper-V.
The only thing we've noticed that needs improvement is the backend cleanup within VMware. There are some little issues there. I would like to see tighter integration with VMware. From a recoverability standpoint, it's great when using VMware. But what we have noticed is that orphan data is an issue within VMware. It doesn't clean up properly when you're moving stuff around.
They could improve their online documentation. From a reliability perspective, the product is around seven. It's less reliable than, others for example. They have one limitation when they have a virtual protection group that does everything. From the ease of deployment perspective, it requires expertise and time. It's not very easy to do auto-tagging or to run multiple VPG genes at the same time. So, from multi-tenant or multi-complex scenarios such as using Zerto external products, such as firewalls, while their own product is good, it's part of a larger ecosystem, that still has a long way to go. The triggering of external products could be better. Combining a master runbook and not just a single VPG or splitting the protection group from the activation plan could be better. There will be a protection policy and activation policy as being done in other products. Better tagging and better multi-term support are needed. Currently, there is no tenant admin support, only global admin support. They should work at the tenant level instead of the global admin level. Right now it's an HPE product; they're no longer a startup. We are hoping that being bought by a major company will do good for them and they'll fix what needs to be fixed. There were very good products, to begin with, and HPE should work to make it even better.
The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that we're only able to replicate one way using this solution. Now, we are evaluating the clustering of Zerto with Microsoft clustering, so we can replicate both ways and both data centers, and have the management server in both data centers. Historically, Zerto has started going into the backup space, and that is when they lost focus on keeping their replication product good. Now, it seems they're finally leaving that backup space, and they're just sticking with replication, so in version 9, they have fixed all of my gripes about the product, e.g. they now support VMware tags, Windows bringing over the time on the target side, etc. All of these little things, they are all correcting, because they're now sticking with the replication product.
I would like to see them continuously improve Zerto's automated functions, such as putting hosts in maintenance mode within vSphere and not having to worry as much about how Zerto is going to react. Rather, Zerto should be able to handle putting various hosts, within either the source or destination side, into maintenance mode without having to worry about the vRA appliances. Sometimes, Zerto almost holds the vSphere environment hostage when it comes to taking certain actions. You really need to be cognizant about what you're about to do. They should further automate that and increase Zerto's ability to handle things like that in a very slick, automated way, without intervention. Zerto could also build more canned automation tools within their product, tools that automatically work with DNS updates to AWS or Azure. Maybe they could provide an area for scripting help or canned scripts, a community or a place where people could grab some scripting. Maybe they could reach into Citrix or F5 load balancer APIs. Also, if you have a host go wrong or you need to put one in maintenance in an emergency situation, especially on the source side, it can require you to fix Zerto and redeploy vRAs or redeploy the little appliances to the host that they're going to be on. Also, depending on what resources it has available, storage or vSphere-wise, I'd like to see it able to balance itself out within the virtual environment, with its storage usage on the destination side. I've only run into these things briefly, so I can't speak about them at the deepest technical level, but I have noticed that they're not as perfect as they could be.
I would like the ability to monitor the performance of some specific components. Right now we're having an issue with local and remote replications with some of the VPGs. Being able to look at individual VPG performance would be helpful. Another thing that would help would be a recommender, or some type of tool that says, "Hey, you're not conforming to best practices." It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on. Another area for improvement is alerts. We're getting so much noise right now in the 8.5 version. The problem is that we don't know which are the ones we need to act on. We don't know which ones are severe versus those that are informational or notice or debug. They have told us that when we upgrade to version 9 we'll be able to tune some of the alerts. That type of alert tuning, where we can get just the emergency and error alerts, would be helpful, while not necessarily tuning out the informational or notice or debug alerts. If alerts could be channeled to a syslog server where we could filter and see which alerts are the priority that would be an improvement. We have a network operation center and for us to operationalize this tool with them, we have to be able to deliver each alert along with an action plan for it. That way they can take the appropriate action if Zerto has some type of error. It would help if the alerts didn't just fall on our storage and data protection team. If we could transfer some knowledge and have other level-one teams look at some of the more basic Zerto alerts and try to resolve them, that would help.
The only issue I've ever had is that I wish that Zerto would work more closely with VMware. There have been a few times that Zerto has released an update but it wasn't supported with that version of VMware. I would like them to coordinate their updates with VMware's updates.
It took me a little bit of time to get used to Zerto's terminology and to relate it back to how you do a backup traditionally. It was a little different. It took a little while to understand what a VPG is and what it does. That's an area that they could probably improve on a little, making the documentation easier to understand.
I know that Zerto can definitely improve some functionalities. I know some of the cloud pieces probably enable that. At the moment, it's doing what we want for us, and what it's doing for us right now is plenty. I can't say there's any improvement that I can see that needs to be done at the moment. I'm not sure if it has throttling, meaning, what's going over the wire and how we can throttle that to reduce the amount of data that's going across the bandwidth. I can't remember if that's something that's in this product. It might be in the more recent version.
We did look at the long-term retention backup feature of Zerto a few years ago, and at that time, it was limited. I can't say what it is right now, but at the time, its functionality was limited in terms of basically where we could save it and how we could save it. Offsite air gapping our backups is important to us to help protect against ransomware, and at the time, it couldn't do that. That would be one area that would be important before we consider using the long-term retention again. I haven't looked at it recently, and they may have addressed this in the meantime, but if not, this would be an area of improvement.
The reporting could be improved in terms of the reports that you can show to auditors to prove that you have done the testing. I provide the reports that it generates now but, it would be great if, at the end of a DR test, it would generate a report of everything that Zerto did. This would include details like what systems were up. Currently, that's not how the report reads. You would have to be an IT person to read the current reports that it produces. I would like for them to be the type of reports that I can put in front of an auditor or the president of our firm that would make sense to them, without me having to interpret and explain the results.
There are still some pieces in testing that aren't automated. There are still some built-in scripts or workflows I wish Zerto would do out-of-the-box, versus having to PowerShell or have a vendor create it, or create it myself. We haven't done a full failback yet of production so I couldn't really say. The failover process is a lot of manual steps, but Zerto is a mechanism that gets the data there. In that aspect, it does what it's supposed to do. But I wish they would expand on their out-of-the-box functionality for the VM. When you fail it over, there are DNS and SQL changes and there are reboots. There are some things I wish that Zerto would facilitate with a checkbox that would do some of these things for me versus having to PowerShell it and put the scripts in a certain place and have support run it. I want it more automated if possible. The issue I have with ransomware is if I don't know I have ransomware in all my recovery points, and if it goes three months, I wish Zerto somehow either bought a company or could tell me that we're infected with ransomware. If I don't know how ransomware and everything gets encrypted, there's nothing to restore back to if all my recovery points have been corrupted. So I wish Zerto somehow had a mechanism to alert me of suspicious activity. We have a Trend product that does that for us. We can get alerts of things that Trend finds, but it's always nice to have layers for your security. We have alternatives, but it would be nice if Zerto had a mechanism to alert me as well. Alerting has also been a pain but it was supposed to be fixed in the newer version and that's. I would like to have more granular alerts.
Previously, our main need for Zerto was actually database cluster servers running fairly old software, SQL 2008 on Microsoft Windows clusters with none of the advanced SQL clustering functionality. Our environment is all virtualized. The way we had to present the storage to our host machines in VMware was via raw device mapping (RDM). Technically, Zerto can do that, but not very well. We have gone to some different methods for our databases, which don't actually use or rely on Zerto because the solution wasn't that functional with RDMs. This is an old, antiquated technology that we are currently moving off of. I can't really blame them, but it definitely is something they thought they could do better than they could in practice. They had a bug recently that has come up and caused some issues. They currently have a bug in their production versions that prevents their product from functioning in some scenarios, and we have hit a few of those scenarios. Aside from that, when it is not hitting a bug, and if we're not trying to use it for our old-style, old-school databases, it functions incredibly well.
We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking.
It has some quirks. We have quirks with appliances. Some things don't really work as expected, but it is minor. It doesn't really affect the overall functionality.
The long-term recovery is a little bit weak in its granularity. Veeam is definitely superior in that aspect, as it's able to provide a granular view of files and databases, et cetera. However, it just kind of depends on what a business' recovery strategy is. From our business perspective, it's really not impactful to us because our recovery strategy is not based on individual files. But, I could definitely see it being a challenge if there is a very large instance of individual files, as a subset, that need to be recovered. I think that if somebody has terabytes of data then Zerto will recover it faster but navigating through the file explorer to get to files is not as easy with Zerto. One thing I don't like about the product, and I know this is where their claim to fame is, but whenever I have a VPG that has multiple virtual machines in it, and one virtual machine falls behind, it'll pause replication on everything else in that job until the one server catches up. The goal is to keep symmetric replication processing going, so the strategy makes sense, but for our business model, that doesn't really work and it has created a challenge where I have to manage each VM individually. It means that instead of having one job that would cover multiple servers, I just have one job to one server, which allows me to manage them individually.
