Helpful for capacity planning, quick restoration, and security
Pros and Cons
  • "The continuation to the public cloud has been especially helpful where I can pretty much work with things like hosts and clusters as part of the data center."
  • "A slight disadvantage of Zerto is that it requires the Windows Server operating system as the base OS. Over time, I would like to see more offerings in that regard. There should be more deployment options other than just the Windows operating system."

What is our primary use case?

A lot of our focus area has been around capacity planning that includes virtual machine rightsizing and then construction for failover and resiliency-type models. The other area that is important to us is looking at data in motion, data at rest, and data in transit.

By implementing Zerto, we wanted to be able to go ahead and focus a lot on workload migration and disaster recovery.

How has it helped my organization?

I can quickly restore data by reverting anything with more or less a nightly backup. I can pretty much have the data through recovery checkpoints, and each of the checkpoints can only be around five seconds apart.

When I need to work a lot with VPGs, it has a lot of capabilities for that. Monitoring is also very important for us. We do work with Splunk, and I am looking a lot around for logs, metrics, and traces. The capabilities that I get are system throughput, and CPU and RAM input/output.

I have used Zerto for immutable data copies. I have pretty much followed a 3-2-1 strategy. We have three copies of production data and two backup copies. We have two different media and then one off-site copy. It has this offering there.

It's helping very much in terms of the malware. They have a ransomware protection capability.

I have used other solutions jointly with Zerto. What is happening is that they have a focus on isolating and locking with a cyber resiliency vault, and what I have been doing more or less around the vault is working with the Delinea Privileged Access Manager solution. So, some areas have intersections with other tools in our stack. I would love to continue seeing more use cases out of Zerto so that I do not have to defer this anywhere else.

It has enabled us to do disaster recovery (DR) in the cloud, rather than in a physical data center. I think of it as a cloud migration tool. Having DR in the cloud is very important for our organization. I use it with Microsoft Azure.

With Zerto, I have seen five-second near-synchronous replication, so there are thousands of checkpoints in one day, and then afterward, I can have a periodic backup. I can space it out between twelve-hour snapshots. We can have one to three checkpoints per day. I can recover to the state seconds before any sort of attack, and I can utilize Zerto's in-built orchestration and automation. I could easily fail over the entire site without any sort of disruption. Those are the things I see very much in terms of positives. There is a lot of information that it can gather with synchronous replication. The other thing is that I have seen other disaster and backup service offerings, and they very much focus on getting a container image installed or some sort of binary file and then deployment from there afterward.

I find it easy to migrate the data. Once somebody understands how Zerto works, particularly around areas for analytics and automation, with the reference architecture, they will be able to quickly deploy it.

I see a lot of visibility in terms of proactive management with SLA monitoring, run metrics, and other things. We are able to test infrastructure using live and personalized data. It, in turn, becomes very much of a team effort.

Zerto provides complete visibility in terms of storage and consumption data. We get to know the capacity and application volumes. I can also address compliance aspects, such as PCI DSS which is important for us as part of the RPO.

They have an intelligent, predictive infrastructure, so I can just pretty much determine the required compute storage and other server networking resources, whether it is on-premises or in the cloud.

It also saves recovery time. We pretty much monitor that information. In terms of time savings, we are able to ensure that we can set up a backup quickly, figure out the integration details with the use of APIs, and meet our requirements around client security. Afterward, there is the cost consideration. Better documentation on the restoration process would be helpful.

Ransomware is one area where we are using Zerto. If we were utilizing another solution, that might have only been AWS-specific, and we might have not gotten much assistance in proceeding with their public cloud vendor as a result. We might have to figure out what we can do around working with an XDR or another mode of ingesting that data for any vulnerabilities and how to focus on encryption thereafter. If we were to consider another vendor, some of them may not have support for Azure. They might be AWS-focused.

Zerto has helped to reduce our organization's DR testing. We can create failover tests seamlessly, and we can do this routinely. We are able to save time and look at how we can discern between RTO and RPO.

Zerto has not reduced the number of staff involved in overall backup and DR management. Our team size is still roughly the same. We have not seen our headcount change as a result, but we do not need to hire external consultants to support a project.

If I wanted to focus on operational recovery, which may be recovering instances in the database with a 15-second data loss, there are systems administrators designed to take care of that. With Zerto's offering, someone can utilize the Zerto solution as opposed to depending on any sort of manual human intervention.

What is most valuable?

The continuation to the public cloud has been especially helpful where I can pretty much work with things like hosts and clusters as part of the data center.

Zerto has near-synchronous replication. I like it very much. They had an acquisition and are now a part of HPE. I see it very much as a robust solution.

What needs improvement?

A slight disadvantage of Zerto is that it requires the Windows Server operating system as the base OS. Over time, I would like to see more offerings in that regard. There should be more deployment options other than just the Windows operating system.

The implementation is very quick and painless, but it would be good to have more information that is not case-sensitive. In the server portal, some fields are case-sensitive. It took some time for me to understand initially.

If a VPG goes down and an application host is not responding, I want to have a little bit more flexibility to automatically point the recovery to other hosts. I would like to see a little bit more flexibility to automatically sustain two applications in their most optimal state. If the VPG is going down and any of the recovery hosts are in maintenance mode, there should be a way for maximum flexibility so that it can automatically utilize Zerto to point that recovery to other hosts.

I want some more information about how to work with bare metal drives. I have been doing some work in capacity planning for using MDM and FormFactor cable and then looking at system throughput, App latency, and a lot of scripts in Linux. I would like to have a little bit more information for anybody needing to work with bare metal drives.

For how long have I used the solution?

I have been using Zerto for several years.

What do I think about the stability of the solution?

I have not seen any service disruption that impacted us. If anything like that were to occur, they would communicate it ahead of time.

What do I think about the scalability of the solution?

It is scalable. We have more than 20,000 endpoints.

How are customer service and support?

I do reach out to Zerto, and if there are any questions, we have a ticket in-house, so everyone is working on reviewing it at the same time. I would rate their support a nine out of ten. There are no negatives.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We were not using a similar solution. 

By bringing in Zerto, some legacy work has been discontinued. There is operational recovery, application migration, and application cloning. These are the three areas where Zerto has helped us.

How was the initial setup?

We have a cloud version. It is a public cloud.

Its initial deployment was straightforward. I have been trying to focus on capabilities and encryption and how a long-term retention repository works, at least looking at the data capture. Another thing is utilizing some information with APIs and cloud scaling. I have broken down a lot of my use cases, and we have Zerto on the public cloud. Based on that, I was able to figure out how to work with features like compute as well as storage.

Its implementation took about two to three months. In terms of maintenance, it requires maintenance. We focus a lot on metrics such as RTO and RPO monitoring. Somebody can also put it in maintenance mode operation.

What about the implementation team?

We had Zerto representatives, and we also had work done in-house. 

I work with a team. Other colleagues are also involved in the effort. We have a team of around ten employees.

Which other solutions did I evaluate?

We did look at a few other vendors' offerings, but we decided on Zerto. Our organization has a partnership with them, and the other thing was that there were a few industry events, and they were able to effectively make a pitch. Their demonstration was very effective. It was also something in which the client was interested in.

What other advice do I have?

To those looking to implement Zerto in their organization, I would advise creating use cases of their own and then trying to see how Zerto effectively helps them. A few areas where they can work are gathering information with the virtual machine rightsizing and being able to go ahead and create resiliency models. Afterward, they can look at compliance. For us, PCI DSS and locating the public cloud environment being used, which in our case was Microsoft Azure, were important. After they have created use cases on their own, they can come to Zerto and see how they are able to effectively handle it. If they are able to think through what they need, they can come up with specific questions and then get Zerto to effectively deliver.

I would rate Zerto a nine out of ten.

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Is easy to migrate data, helps reduce our recovery and staff time
Pros and Cons
  • "Zerto is scalable."
  • "The RPO for our SQL server has room for improvement."

What is our primary use case?

We use Zerto for disaster recovery and cloud migration.

How has it helped my organization?

The near-synchronous replication is valuable to our organization.

Zerto's immutable data copies three-two-one rule is great.

The ability to block ransomware attacks and help recover our servers is great.

Since we don't have a backup data center, Zerto's cloud disaster recovery is of the utmost importance.

The recovery point objective for our virtual machines is good. We haven't encountered any significant issues. However, there have been some delays due to the substantial volume of data being written to the SQL server.

Migrating data using Zerto is easy.

Our RTO went from three days to a few minutes after implementing Zerto.

In the event of a ransomware attack necessitating data recovery, Zerto would undoubtedly prove invaluable in expediting the process.

Zerto has helped reduce our recovery time from days to minutes.

Zerto has reduced the time our staff spends on data recovery by 25 percent.

What needs improvement?

The RPO for our SQL server has room for improvement.

On-premises to cloud migration lacks certain features, such as the ability to directly rename virtual machines. In the cloud, renaming resources often requires cumbersome workarounds like cloning and manual renaming.

For how long have I used the solution?

I have been using Zerto for four years.

What do I think about the stability of the solution?

Initially, we had stability issues with the older versions but now I would rate the scalability an eight out of ten.

What do I think about the scalability of the solution?

Zerto is scalable.

How are customer service and support?

The level one technical support is slow to respond and we usually need to escalate our issue to get a resolution.

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

We previously used Azure Site Recovery and switched to Zerto because it is more user-friendly with more features.

How was the initial setup?

While the initial deployment presented some challenges and took approximately two weeks to finalize, subsequent deployments have been significantly more streamlined.

What was our ROI?

In the event of a disaster, we will certainly see a return on investment.

What other advice do I have?

I would rate Zerto an eight out of ten.

Deploying Zerto in the cloud saves us costs on maintaining on-prem hardware.

Which deployment model are you using for this solution?

Private Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Our customers like the fact that they can restore within seconds
Pros and Cons
  • "Another advantage is the ease of use. You can click through instead of typing in the code. It's all already scripted down to the network adjustments within the VMs and the timed delays for servers that need to come up in sequence. Overall, it's a good package for us to use. We started using it in about 2018 and haven't looked back."
  • "It would also be nice if you could update without having to download a new installation file for Zerto Virtual Manager. Within the app, it could prompt you to install and perform the installation from within the application. Generally, it's relatively easy to use, but it gets a little complex when customers have special network requirements and need to customize how long they want the save points to be retained. We need to work with the storage team on the backend to see what makes the most sense for the client."

What is our primary use case?

We're a managed services provider that uses Zerto primarily for disaster recovery as a service. We offer Zerto as a DR option for our clients. Our customers in the Bahamas need a DR option outside of the hurricane belt, so we have workloads throughout the world to ensure our customers have somewhere to restore from. 

Currently, we run Zerto in a vCloud environment. All of the services are brought up in a vCloud environment. It saves us from having to constantly buy equipment. The vCloud environment enables us to spin up an environment as needed instead of having unnecessary hardware sitting there using resources.

How has it helped my organization?

We haven't had any major disasters that required us to use Zerto, but we perform two or three live failover tests with clients. Everyone seems to be pretty happy with the product and the turnaround time.

It's all about client satisfaction. They may not understand the underlying tech architecture, but they want to know how fast we can bring the environment back up. We can achieve fast restorations and restore sections if needed instead of the entire environment. It's been a great experience for us and our customers. 

What is most valuable?

The RTO/RPO times are fast. The speed is probably the biggest selling point for us. It's not live replication, where you have two sites up at the same time, but our customers like the fact that they can restore within seconds. 

It takes them nearly to the last point of connectivity, so it's seamless and easy to operate. It's easy to operate, and customers feel that they have a level of control. With some platforms, most things need to be done by the provider, but customers have a management platform in their environment. They can run tests without our direct involvement. 

Another advantage is the ease of use. You can click through instead of typing in the code. It's all already scripted down to the network adjustments within the VMs and the timed delays for servers that need to come up in sequence. Overall, it's a good package for us to use. We started using it in about 2018 and haven't looked back.

What needs improvement?

We have an issue with the management platform because we don't always upgrade to the latest version, whereas the customers tend to constantly upgrade. Sometimes, we lose connectivity because something isn't supported. 

For example, we have VMware version 7 update 3. This morning, a customer upgraded it without informing us. It's their responsibility to notify us because our environment is large, and we don't update every time a new version comes out. It's somewhat of a pain. 

In addition to data, the other thing would be the hardware versions for VMware. I finally found a proper support matrix, but we ran into a few problems in the early stages. I don't know how to address this, but maybe when the version is going to update, the client could get a prompt saying that the cloud location is not on that same version. It would be a more efficient way to tell them instead of trying to figure it out. 

It would also be nice if you could update without having to download a new installation file for Zerto Virtual Manager. Within the app, it could prompt you to install and perform the installation from within the application. Generally, it's relatively easy to use, but it gets a little complex when customers have special network requirements and need to customize how long they want the save points to be retained. We need to work with the storage team on the backend to see what makes the most sense for the client. 

For how long have I used the solution?

I have used Zerto for about five years.

How are customer service and support?

I rate Zerto support nine out of 10. I haven't had any serious issues aside from the problem with version differences between a client's environment and ours. That is just a matter of striking a balance with the clients. An IT environment can't update too frequently because you don't want a change to break something. Unfortunately, you can't stop the customer. 

Support has been good about helping us troubleshoot those issues. It's easy to run a diagnostic tool and get the file. It's difficult to pull down a diagnostic file in some solutions because you need to do it via a command line. With this, it's just a couple of options you select. You run a diagnostic, save the file, and send it. 

How would you rate customer service and support?

Positive

How was the initial setup?

I work on the cloud management side, so it was already deployed. I wasn't involved in deploying the cloud portion. However, I installed all of the virtual management for customers and set up the environment for them. That part of it was easy. It was a click-through thing. Most of the time, we'll guide the customer through the process, so they can see it as well. We show them the step-by-step process of performing the updates. 

What's my experience with pricing, setup cost, and licensing?

Zerto is like a Ferrari. It's very fast but not the cheapest solution. You're paying a high price for quality and the assurance that you will have the environment up and steady. 

There are tradeoffs, too. Our clients spend money on licensing but save on equipment. The customers could either buy a bunch of equipment or pay for Zerto licenses. That's where we come in. We provide you with a cloud solution that doesn't cost all this money upfront. The prices could always be better, but we don't complain so much about it because the savings come from other places.

What other advice do I have?

I rate Zerto nine out of 10. A lot of people are trying to convince us to look at VMware backups instead, but I don't see the urgency because Zerto works for us. I don't see anything on the market that can restore in seconds as opposed to minutes or hours. For us to switch, we would need something that beats Zerto. Right now, nothing beats it.

Near zero RPO and very little data loss as far as recovery time
Pros and Cons
  • "Another big attraction is the near zero RPO. A lot of other products have minutes, half-hour, or an hour RPO. We have proof indicating that Zerto is near zero, or a matter of minutes, as far as the RTO is concerned. So again, that's another attractive offering where you can actually fail something over and bring that back up in a target location in a matter of minutes. Meaning very little data loss as far as recovery time. It's fantastic."
  • "I wish they would...develop their PowerShell module to be more robust. So instead of having to rely on the API to actually include a PowerShell command, it would let you create VPGs, delete VPGs, modify VPGs, etc. This would ease the automation effort of deployment and decommissioning and I'd really appreciate that."

What is our primary use case?

We are protecting 91 terabytes worth of data that consist of 200 virtual machines over the span of 96 tracking groups. We currently have 300 licenses and Zerto provides protection for our critical production systems with a 24-hour journal. We do utilize another platform to backup our entire enterprise as well as handling retention for a longer period of time.

We limit Zerto access to our platform engineers so either our Linux administrators or our Windows administrators use the solution. When a virtual machine is tagged as the article, in other words something that should be replicated to a target data center, they have the authority to create a VM and make sure it is protected via Zerto.

We have an annual DR test requirement. Initially, we used Zerto for testing a subset of our production systems and generated reports that would validate that the tests were successful. We leveraged Zerto to test failover for over 200 VMs by running it in the test scenario. We ran it for a couple of days and tested connectivity to verify that all the virtual machines were up and running and that disk integrity was fine.

Over the years, we have moved from an offline test scenario to an actual real-life failover for subsets of applications. For a couple of years now, we have failed over applications into another data center and have run production from there on a small subset. Our vision going forward is to avoid these offline once a year tests and to periodically move applications from one data center to another in a real-time testing scenario.

We currently have a production data center and then we have a co-location, which we are leasing. So we actually have two locations where we can failover. We do have a small cloud presence in Azure, and we have started a small cloud presence in AWS as well, but we are not running any IaaS virtual machines in those clouds. There's really been no cost-savings at all in the cloud so we've brought those work machines back on-premises.

How has it helped my organization?

Prior to Zerto, we used a third-party offsite facility and a team of 25 individuals, where we would restore over 300 VMs in our network, to prove annually that we can recover our data. Since adopting Zerto, we've pretty much reduced all of that VR testing to about four team members. We've significantly reduced our costs by staying on-premises and time from only four individuals instead of a whole team of 25.

What is most valuable?

The first benefit, right out of the gate, was to duplicate a subset of our production environment and test it in an offline network scenario. That initial test was fantastic as was all of the reporting to prove that we have done those tests. Another big attraction is the near zero RPO. A lot of other products have minutes, half-hour, or an hour RPO. We have proof indicating that Zerto is near zero, or a matter of minutes, as far as the RTO is concerned. So again, that's another attractive offering where you can actually fail something over and bring it back up in a target location in a matter of minutes. Meaning very little data loss as far as recovery time. It's fantastic.

The main reason why we love Zerto is because we have a VMware environment. What we're doing now with VMware is we leverage NSX-T which gives us the ability to have a shared address space across two physical data centers. By using Zerto with an NSX-T, we can failover applications without re-IPing or anything like that. So it's a matter of literally shutting down the forced side and powering up the other side in minutes. It works fantastic and that is definitely our future DR strategy as well as our future failover testing.

What needs improvement?

I haven't seen any significant features or improvements in the past few major version releases. The only challenge I have with Zerto today, and over the past few years, is that it seems like a lot of development and effort is going toward the cloud. Since we're utilizing the solution with an on-premises hypervisor, it seems like development for our needs is kind of stuck.

The other thing I wish they would do is to develop their PowerShell module to be more robust. So instead of having to rely on the API to actually include a PowerShell command, it would let you create VPGs, delete VPGs, modify VPGs, etc. This would ease the automation effort of deployment and decommissioning and I'd really appreciate that.

For how long have I used the solution?

I implemented the solution back in the fall of 2016.

What do I think about the stability of the solution?

Zerto is very stable and requires little maintenance. We probably update Zerto twice a year. There's been no real outage issues that we've encountered. There have been a few times where we've had issues with VMware which in turn provided a hiccup towards Zerto. Though Zerto was a symptom and not the root cause.

Zerto provides continuous data protection and we've had very little disruption. We've gone through mobile versions starting with version six something and we have gone through the various upgrade cycles without any major issues.

What do I think about the scalability of the solution?

Zerto seems very scalable. I can't really comment further on that because we've only had two license upgrades from 200 to 300 virtual machines. I haven't really tested this on a very large scale like for over a thousand VMs or anything close to that. From what we've utilized it has scaled, but I'm really not a good example because we manage a smaller subset of virtual machines.

As far as our key-protected systems, we're at the 280 marker so we don't see ourselves growing any more. License increments are 25 or 100 and if we did grow, obviously, we would increase our license count. Although we've had 300 licenses for a few years now so we've kind of found our sweet spot.

How are customer service and technical support?

There's been a couple of support calls along the way, but support has been very helpful and very responsive in correcting our issues.

How was the initial setup?

Back in 2016, we conducted a 30-day POC with Zerto and that was enough time to fully implement the solution and even utilize it. We were really impressed that we could actually use Zerto from start to test within a 30-day timeframe.

We found the setup and deployment process to be very simple and not complex at all. We installed Zerto on-premises with just regular employees. It was a team of two engineers and a database administrator and that was it. After a little bit of research on the prerequisites we literally ran the installation setup. It was a breeze and there were really no custom tweaks or anything that had to be done post-setup.

The solution is very user intuitive, from the initial setup of the application and installation all the way to actually getting data in there by creating virtual protection groups and populating VMs.

What's my experience with pricing, setup cost, and licensing?

As far as our IT budget is concerned, Zerto is a little bit expensive. But as far as the value that it provides, it is completely justified by all of the savings. Reducing the labor of DR failover exercises or its reporting functionality for our audit teams has saved a lot of soft dollars. Also, failing over our workloads to another data center and proving that it does work is priceless. On the other hand, the price consideration is why we're only protecting a subset of our virtual machines, those that are deemed DR critical, versus protecting everything.

Which other solutions did I evaluate?

We did evaluate a few different products before selecting Zerto. We looked into Commvault and Veeam. We also looked into VMware's Site Recovery Manager. Having a near zero RPO and a very short RTO was the main difference between Zerto and the products we evaluated.

What other advice do I have?

The biggest advice would be to compare Zerto to another product side-by-side and actually do a demo of both products. And then at that point, post-demo, the decision will be very easy.

On a scale of one to 10, where 10 is best, I would rate Zerto a nine plus. Unfortunately, no product walks on water, so they're never going to get a 10. There's room for improvement everywhere for sure, but I'm extremely happy with the product.

Reduced our overall compute and storage footprint, while continuous protection gives us countless restore-point opportunities
Pros and Cons
  • "The granularity enables us to failover specific workloads instead of an all-or-nothing type of scenario, where you have to move your entire IP block and your data center, or you have to move large chunks of VMs. Those situations also make it prohibitive to test effectively."
  • "The replication piece with the built-in WAN compression is important because the network circuit that we send our replication traffic across isn't actually behind our normal WAN accelerators. We were able to use Zerto's built-in WAN acceleration to help those workloads compress."
  • "The replication appliances tend to have issues when they recover from being powered off when a host is in maintenance mode. Sometimes you have to do a manual task where you go in and detach hard disks that are no longer in use, to get the replication appliances to power back on. There are some improvements to be made around the way those recover."

What is our primary use case?

We are using it for disaster recovery for our day-one applications that need to be up first, upon failover.

How has it helped my organization?

We previously had our Microsoft SQL Servers set up as clustered pairs, with the primary in one data center and the secondary in the other, and they were staying in sync via SQL Server Log shipping. That was not a very efficient way to get SQL servers failed over. There were also some things that weren't replicated through log shipping, such as the SQL Server Agent jobs that are defined on the server, or the custom permissions that are set up for the different roles. Zerto was able to replicate the entire server, including the jobs and the permissions, and eliminate the need for us to have that secondary server. We were able to break all of our SQL clusters and just have standalone SQL Servers. It helped to increase our efficiency with failover and reduced our overall compute and storage footprint around SQL by about 40 percent.

When failing back or moving workloads, the solution saves time and reduces the number of people involved. The time from the initiation of a failback to the completion is about five minutes for us. We've also made some tweaks in the DNS to help that to update and replicate quickly so that we're not waiting for that, even if the resource is available. As for the number of people involved, for SQL especially, it used to require getting the SQL team involved and they would do everything manually. Now, anybody can just click through the recovery wizard and perform the failover.

Our savings from Zerto are around licensing and how we structure our current environment. We were able to save money with our on-prem deployment, but we don't use it for cloud.

And in terms of downtime, every time we test a failover it's non impactful to operations, because we're able to do testing in an isolated environment. Before, if we wanted to test our failover processes it was going to create a production outage. That is no longer the case. Before, when we were doing regular DR tests, I would estimate the cost of the downtime to have been about one weekend per quarter. That's the time we would have to take to do that. Only if we were to do a live failover as a test, which would probably not be done more than once a year, would we really have to worry about impacting any operations.

What is most valuable?

The most valuable features would be the

  • granular configuration of your SLAs
  • built-in WAN compression as part of the replication 
  • easy wizard-based failover.

The granularity enables us to failover specific workloads instead of an all-or-nothing type of scenario, where you have to move your entire IP block and your data center, or you have to move large chunks of VMs. Those situations also make it prohibitive to test effectively.

The replication piece with the built-in WAN compression is important because the network circuit that we send our replication traffic across isn't actually behind our normal WAN accelerators. We were able to use Zerto's built-in WAN acceleration to help those workloads compress.

The failover is important because that way I can delegate initiating a failover to other people without their having to be an expert in this particular product. It's easy enough to cross-train people.

Continuous data protection is Zerto's bread and butter. They do all of their protection through your journaling and that continuous protection gives you countless restore-point opportunities. That's extremely important for me because if one restore point doesn't work, because it is a crash-consistent restore point, you have so many others to choose from so that you really don't have to worry about having an app-consistent backup to recover from.

Zerto is also extremely easy to use, extremely easy to deploy, and extremely easy to update and maintain. The everyday utilization with the interface is very easy to navigate, and the way in which you perform testing and failover is very controlled and easy to understand.

What needs improvement?

The replication appliances tend to have issues when they recover from being powered off when a host is in maintenance mode. Sometimes you have to do a manual task where you go in and detach hard disks that are no longer in use, to get the replication appliances to power back on. There are some improvements to be made around the way those recover.

My other main inconvenience is fixed in version 8.5. That issue was moving virtual protection groups to other hosts, whenever a host goes into maintenance mode. That's actually automated in the newer version and I am looking forward to not having to do that any longer.

For how long have I used the solution?

I've been using Zerto for coming up on four years.

What do I think about the stability of the solution?

My impression of its stability is very positive. It doesn't seem to have any issues recovering after you shut down any of the particular components of the application. It seems everything comes back up and comes back online well. 

Sometimes the replication appliances will stop functioning, for one reason or another, and most of the time a power cycle will resolve that. But anytime that I do have a sync issue, support will generally be back in touch with me within the first half hour after opening a ticket. They're very responsive.

What do I think about the scalability of the solution?

The scalability is able to take on any size environment. We don't have a huge environment here. We only use it across 20 hosts, 10 at each site. They're very large hosts. If you have more than a certain number of virtual disks protected on a single replication appliance, the replication appliance will automatically make a clone of itself on that host to accommodate the additional virtual disks. It seems to be built to scale in any way that you need it to.

While our hosts are very large hosts, we don't have any current plans to extend that deployment because we have capacity to grow within our current infrastructure footprint, without having to add on resources.

How are customer service and technical support?

I rate their technical support very highly. They're very responsive. Usually within the first 30 minutes of opening the case, someone has tried to reach out to me. I will just get a screen share, or a reply to my call with an answer, or a KB article. I have a very positive impression of their support.

Which solution did I use previously and why did I switch?

We were using Site Recovery Manager for several years, and I always struggled with keeping that functioning and reliable. Every time something changed within the vCenter environment, Site Recovery Manager would tend to break. I wanted to switch to a DR product that I could rely on.

In addition to Site Recovery Manager, we were also using NetApp SnapMirror. We are still using that for our flat file data which is non VM-based. We have Rubrik as our backup solution because, while we replicate our backups, there's not any automation behind bringing those online in the other sites. So it's a manual process to do disaster recovery.

We were having to utilize those solutions to do the failovers for our day-one application in SQL and they were inefficient and ineffective for that. Zerto was able to come in and target those workloads that we needed better recovery time for, or where we needed a more aggressive replication schedule. Zerto is supplementing those other solutions.

Zerto is easier to use than the other solutions. There's definitely more automation and there are more seamless failover activities.

How was the initial setup?

When I deployed the solution, it took certainly less than a day to get it up and running. The upgrade process has been fairly seamless and painless, in the past, as we have gone from one version to the next. That includes some of the features they've enhanced, where it automatically updates the replication appliances as well as the management pieces.

We have two data centers and they're both Active-Active for one another. Our deployment strategy for Zerto was to stand up a site server at each one, pair them together, and then start identifying the first workloads to add into Zerto protection. We started with our SQL environment. 

I was the only one involved in the deployment. If I had questions I would ask my account team. My sales engineer and the account rep are both very knowledgeable. But I actually didn't need to open a support ticket as part of the deployment. It was very easy and straightforward.

About five of us utilize Zerto. I am the infrastructure engineer, focusing on the compute side of the house. We've got a storage engineer. My manager is an applications delivery manager who uses it. We've got another senior network engineer who focuses more on the runbook side of things, and he uses it. And my backup, who is our Citrix guy, is starting to use it.

Zerto doesn't really require any particular care and feeding. Whenever a new version comes out that has features sets, I'll decide when I'm going to update it and do that myself. It doesn't really even require a support call. It's pretty straightforward. For each management appliance, updates have taken 10 to 15 minutes, in the past. And it's just a couple of minutes for each replication appliance.

What was our ROI?

Our ROI is quite significant. The SQL cost savings alone would be in the hundreds of thousands of dollars per year. That's due to the fact that we don't need to have our SQL clustering set up as an always-on cluster, which would need to be a higher tier of Microsoft licensing. We're able to use SQL standard for everything, and that wouldn't be possible without a third-party like Zerto to do the replication and failover.

What's my experience with pricing, setup cost, and licensing?

Get the Enterprise Cloud license because it's the most flexible, and the pricing should come in around $1,000 per VM.

Support is an additional cost. We are currently doing three years of support. There's an additional 15 or 20 percent of overhead during each year of additional support for each license.

What other advice do I have?

Definitely take the free trial and put it through its paces, because you really can't break anything with it, given the way that you can do the testing. It gives you a good opportunity to play with the tools without having to worry about causing any problems in the environment.

We have plans to evaluate the solution for long-term retention. I'm going to start testing some of their features once we upgrade to version 8.5, and then we'll evaluate if it makes sense to do that or not. We do have other backup products that we're evaluating alongside of that though.

The solution has not reduced the number of staff involved in overall backup and DR management. We already run a very lean engineering team.

I got what I expected. I'd actually been trying to bring the product in since 2014 but I kept not getting budget funding for it. I feel satisfied with what I ended up with and I'm glad that we were able to move forward with the project.

Saves significant recovery time, doesn't require a lot of resources, and eliminates the need for a dedicated physical data center
Pros and Cons
  • "Zerto stands out for its user-friendly approach to data protection and recovery, allowing for quick and efficient backups and restores."
  • "Zerto's setup process could be simpler."

What is our primary use case?

We store a lot of raw data for reporting and use Zerto to protect that data.

Before implementing Zerto, we lacked a data protection and recovery solution, resulting in a significant data loss incident of approximately 70 percent during a past event.

How has it helped my organization?

Zerto is easy to use.

The near-synchronous replication offers a critical advantage for our customers' multi-platform environments by providing continuous data protection with minimal delay.

The main benefit of Zerto is that it doesn't affect the performance of the cloud platform while protecting the data. We realized the benefits of Zerto within the first three months.

Zerto's implementation has significantly improved our recovery time objective, allowing us to get our systems back online much quicker.

Zerto has significantly improved our disaster recovery capabilities, reducing downtime from days to just two hours.

With Zerto in place, our disaster recovery time has been reduced to a maximum of two days, whereas previously we lacked a recovery solution altogether.

Our disaster recovery testing with Zerto exceeded expectations. We aimed to restore all data within five days, but using Zerto's capabilities, we achieved a full recovery in just two days.

Zerto saved our staff three days of work, freeing them for other tasks.

Zerto's continuous data protection, journal-based recovery, automation, multi-cloud and hybrid cloud support, and non-disruptive testing have significantly improved our IT resilience strategy. These features not only enhance data protection and improve our Recovery Time Objective and Recovery Point Objective but also provide the flexibility and scalability needed for a robust IT environment.

It facilitates a cloud-based disaster recovery solution, eliminating the need for a dedicated physical data center to ensure business continuity in the event of an outage.

Zerto was our disaster recovery solution of choice because it offers a cloud-based implementation, which perfectly aligned with our organization's prioritization of cloud-based disaster recovery.

What is most valuable?

It stands out for its user-friendly approach to data protection and recovery, allowing for quick and efficient backups and restores.

What needs improvement?

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.

For how long have I used the solution?

I have been using Zerto for ten months.

What do I think about the stability of the solution?

We sometimes face challenges that require multiple hours of downtime but it is rare. I would rate the stability eight out of ten.

What do I think about the scalability of the solution?

Zerto is expensive.

How are customer service and support?

The technical support is quick to respond.

How would you rate customer service and support?

Positive

How was the initial setup?

Integrating the initial deployment into our infrastructure proved to be a complex undertaking.

To ensure a smooth implementation, we prioritized planning and engagement, starting with management and then incorporating other stakeholders. We piloted the project with the operations team for a month before a full organizational rollout.

The deployment took around one week and involved six people.

What about the implementation team?

The implementation was completed in-house.

What was our ROI?

Zerto provides a return on investment through the peace of mind we get knowing that all of our data is protected.

What's my experience with pricing, setup cost, and licensing?

Zerto is expensive.

Which other solutions did I evaluate?

After considering both Commvault and Carbonite, we ultimately decided Zerto was the best fit for our data protection needs.

Zerto emerged as our choice for data protection because its feature set directly addressed the specific needs of our organization.

What other advice do I have?

I would rate Zerto eight out of ten.

Maintaining Zerto is manageable as we have a dedicated team of three people responsible for its upkeep.

Our organization consists of 40 analysts in one site.

Zerto provides robust data protection and excels in disaster recovery for businesses, but its cost may be steeper compared to other solutions.

Had a major impact on our RTOs and the near-synchronous replication is exceptional
Pros and Cons
  • "Zerto's two main features are ease of management and that the product just works. It does what they say it'll do."
  • "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."

What is our primary use case?

Our primary use cases are for disaster recovery replication side to side. 

We were running VMware Site Recovery Manager and it ran well. It was a great solution compared to what we had before. We didn't have disaster recovery issues. We were just doing our test. It ran superbly. Zerto improved the amount of time it took to failover and address any issues. We went from failing over in about three or four hours during the test to it taking one hour. It was very fast.

It's in a single department in a single company. Luckily, we don't really have to support much of our field force. We have approximately 4,000 agents who are in eleven states, but we don't have to go out into the states. We're on in one building and it's one business unit. We manage the failovers but it's just one group management.

Approximately four users use the solution.

What is most valuable?

One of the most valuable features is the ease of management. It's very easy to manage. My team grew and a team member took over my role for Zerto support. He was able to pick the ball up and run with it. It was very easy for him to pick it up and go forward. I haven't had to do a lot of management of the product. 

Our RTO is between four to ten seconds to our site, which is about a hundred and fifty miles north of my location. We bought dedicated lines and we've been very happy with Zerto's performance. 

Zerto's two main features are ease of management and that the product just works. It does what they say it'll do.

The near-synchronous replication Zerto offers is exceptional. Our pipe is 10 GB and we haven't overloaded that connection. We are very satisfied with it.

During our test last year, we moved systems around for users to test with. We had some misconfigurations in the journal sizes, they just weren't big enough. There was logging left on some SQL servers. Our DR test lasted for three days. We had a dedicated group come in and test. We failed back to production and then put it in the test phase again. We did it all within thirty minutes, and it worked very quickly. We were very satisfied.

Zerto has had a major impact on our RTOs. We've been feeling the impact for a while. It's steady here. It's exceptional. SRM dwarfed as far as our targets for RTOs. 

Zerto has reduced our DR testing. It reduced the amount of time we have to test because it's so easy to failover. We've been very pleased with that. It's even given us the option of where we might be able to test more often anytime. We would like to get to a place where we test it once a month where we would allow some business units to test, and then do another business unit the next month.

It used to take us a week for the failover process and testing. The testing has been majorly reduced to where it now takes a day. It took a day to failover, to get everything lined up and running, and it never worked. We never were able to officially have a successful DR test. SRM fixed that and then Zerto took it to the next level. It improved drastically. This has freed up staff to work on other tasks. It used to be that we needed a room full of people for the test where we now need two. 

What needs improvement?

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. 

For how long have I used the solution?

I have been using Zerto for six years.

What do I think about the stability of the solution?

We've been very satisfied with the stability of it. 

What do I think about the scalability of the solution?

It is scalable. 

How are customer service and support?

Support has been pretty good and responsive. I would rate them a nine out of ten. They're good. 

Sometimes getting in touch with somebody is hard. We're not that big of a customer though. 

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

It's been easy for new users to pick up and it was pretty easy for multiple people to work within the UI.

How was the initial setup?

I was indirectly involved with the setup. It didn't take very long, it was like doing an upgrade. 

You just build the servers and the proxy up, install the VRA, and then one by one had them sync.

Seven months ago we had to do a complete resync which took about four to five days. It was straightforward. There is a lot of documentation on Zerto's support site. My advice would be to get the documentation off their site. Open a ticket for support at the same time. 

What was our ROI?

We have seen ROI in terms of resources and time. For our overall management of the system, it doesn't require too many resources. The upgrades are not too bad. You may have to dedicate a staff member to do it for a couple of days. I didn't have a lot of experience with it and the two upgrades I did were simple.

In terms of time, it has saved us north of 30%. It cut down on a lot of manpower. There has been a reduction in our management pattern from other prior solutions.

What's my experience with pricing, setup cost, and licensing?

You pay to play and it's not cheap but it's worth it. 

What other advice do I have?

We know we have the capabilities to do disaster recovery in the Cloud rather than in a physical data center. We're replicating about 150 miles north of us. That's probably going to happen in the next five to ten years for us. We're making a pivot to where we know we're going to have to go that way with some of the cloud solutions.

We have not had to use it for data recovery due to ransomware. We have gone through the industrial hardening of our environment. We have been rated as very mature as far as our security stands. We have actually had some counterparts that experienced some issues and they didn't have anything in place, and it was very bad for them. Luckily, we have not had to use it in that capacity. We feel really good about its capability from the testing we've done. We know we can use it for malicious attack response.

We have tested it to help protect VMs in our environment and we have found that it will work for that. We got decent results with testing and I was very impressed.

In terms of it reducing our overall backup and disaster recovery management, it hasn't. We needed two staff members for the last two solutions we used. This year we will need three because I will also be involved with Zerto.

Zerto has replaced our DR and replication legacy solution. We're using Veeam for our backups but Zerto has replaced everything replication-wise. It saved costs to manage them by 20%.

My advice would be to do a POC for its concept and everything you get. Get it. Do it. It's a good product. I have friends that work with other companies that provide similar services and one of their engineers told me that you can't beat Zerto. 

I would rate them an eight out of ten.

Performs fast disaster recovery, is easy to configure and manage
Pros and Cons
  • "The ability to quickly bring up VMs within a test environment allows us to test our disaster recovery functions and ensures that they would function just as well in an actual disaster scenario."
  • "Zerto needs to improve its support for VMware Lifecycle Manager."

What is our primary use case?

We currently utilize Zerto as our disaster recovery solution. With Zerto, we replicate production virtual machines to our DR site. This approach enables us to recover and bring everything back online in a disaster swiftly. Our recovery point objective can be as low as five seconds, depending on the replication point.

Additionally, we employ Zerto for scaling purposes and for conducting upgrade testing. This entails spinning up VMs in an isolated environment, allowing us to perform various tests. For example, a few years ago, we tested the upgrade of our active directory domain controllers. By validating processes within this environment, we can ensure their smooth execution in production. These are the two primary use cases for Zerto in our organization.

How has it helped my organization?

Zerto is very user-friendly. We can select the VMs by installing a small agent specifically designed for the host. This agent identifies all the VMs. Zerto integrates smoothly with VMware, which is our primary core platform. I believe it also functions well with other hypervisors, although I am only familiar with VMware. Therefore, the integration with vSphere simplifies the process of creating groups, runbooks, and other components necessary for building our disaster recovery environment.

Zerto's near-synchronous replication performs admirably. Many times when I check, we are only about five seconds behind in terms of production time. Of course, this does depend on network performance. There have been instances where the delay exceeded five seconds due to network blips or other issues. However, for the most part, we consistently remain within a five-second range of our production environment.

As a manufacturer, a significant portion of our operations relies on timely execution in order to ensure efficient production and timely delivery of our products. We closely coordinate with external partners and customers to minimize downtime and maintain a seamless real-time production process, which is crucial for us.

The ability to conduct faster disaster recovery testing and the potential for quicker recovery in the event of a disaster have been greatly improved. Before using Zerto, our approach involved log shipping and manual recovery, which meant that the best we could do was recover the previous backup from the previous night, assuming the backup was successful. This process would take hours or even days. However, with Zerto's automation, we can now recover within seconds—five, ten, or twenty seconds from the point of the outage. We can bring systems back online automatically and at a significantly faster pace than our previous manual approach allowed.

Zerto has significantly improved our recovery time objectives compared to what they used to be. Previously, we would have to restore from backups from the previous night and manually configure systems. Therefore, the recovery time objective has likely decreased from days to approximately an hour, or perhaps even less. It's challenging to determine the precise timeframe in a real disaster scenario since we conduct disaster recovery testing. However, it is undoubtedly much better than it was before, although pinpointing the exact time of an actual disaster is somewhat different.

Zerto has helped us reduce our organization's disaster recovery testing from several days of preparation to just a single day.

What is most valuable?

Zerto is easy to configure and manage. The ability to quickly bring up VMs within a test environment allows us to test our disaster recovery functions and ensures that they would function just as well in an actual disaster scenario. This enables us to swiftly recover in the event of a disaster.

What needs improvement?

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.

For how long have I used the solution?

I have been using Zerto for ten years.

What do I think about the stability of the solution?

Zerto is highly stable. It is rare to encounter any issues with it. Typically, any problems that arise are due to changes made on our end that may have inadvertently affected it. However, Zerto remains an exceptionally stable product.

What do I think about the scalability of the solution?

To the best of my knowledge, Zerto can scale to the extent that we require. I am not aware of any limitations, as we have not encountered any thus far.

How are customer service and support?

The technical support is generally very prompt in responding, and highly knowledgeable, and they will continue working with us until the problem is resolved.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We previously used Dell RecoverPoint for Virtual Machines and completely replaced it with Zerto.

Zerto is much easier to use compared to RecoverPoint. Previously, with RecoverPoint, we could only program-specific logs, and the VMs we wanted to replicate had to remain on those logs. If we moved the data off those logs, replication would be lost. However, Zerto keeps track of the VM regardless of its location, making it superior to RecoverPoint in terms of configuration and management.

Zerto is a more cost-effective product than Dell RecoverPoint.

How was the initial setup?

The initial setup is straightforward. We need a virtual machine, install it, push it through, and configure it to communicate with the host for deployment. I mean, it's a very straightforward process. Two people were involved in the deployment.

What about the implementation team?

The implementation was completed in-house.

What was our ROI?

The human resources necessary to perform a disaster recovery test are undoubtedly available. It is more economical than RecoverPoint. Now, it has been many years, and I am uncertain about the cost disparity. However, on the whole, there is a decrease in various aspects regarding the product's cost and the number of work hours needed for disaster recovery testing which is a clear return on investment.

What's my experience with pricing, setup cost, and licensing?

The pricing is straightforward. We are on an enterprise licensing model, and it is based on a per-VM basis. We have the option to purchase them in blocks. This approach is quite cost-effective as we do not replicate our development and testing environments. We only replicate the production environment. Therefore, we are not paying for the entire setup, but only for what we are actually replicating.

What other advice do I have?

I rate Zerto a ten out of ten.

Currently, we have a separate product that we use for backup, which has immutability features. However, we do not currently employ Zerto for immutability purposes.

We have considered using the cloud for disaster recovery, but currently, we maintain the same hardware at both locations. However, since we conduct all of our firmware testing and upgrades on our disaster recovery site first, we have decided to keep our own disaster recovery site instead of attempting to do it in the cloud.

We could easily transfer data to the disaster recovery system. One of Zerto's functions is to replicate data from virtual machines or migrate entire virtual machines, although we haven't utilized it for that purpose.

The only maintenance required is typically software updates. Whenever a new version is released, we must go through the process of upgrading Zerto. Other than that, unless there are any issues, it generally operates smoothly.

We just need to ensure that we know the number of virtual machines we would be replicating so that we can obtain the correct licensing. Otherwise, we will have to backtrack. If we underestimate, we will need to provide additional licensing. It is important to determine this information upfront, as well as the bandwidth between our site and the replication location, as it also affects our recovery objectives.
