Zerto Reviews

We use Zerto for disaster recovery. That is our main use for it.

Everybody at the top wants to be able to hear about our disaster recovery timelines. The ability to restore our Practice Management systems several states away in a matter of 45 minutes is phenomenal.

I love the near-synchronous replication of Zerto. We are based out of Alabama but we have our off-site disaster recovery in Colorado. Being able to have data very quickly over in Colorado is phenomenal.

Zerto has enabled us to do disaster recovery in the cloud, rather than in a physical data center. Having DR in the cloud is super important for our organization. That is where our business intelligence center lives. Without that data, we do not make money.

We have used Zerto to help protect VMs in our environment. It has been a huge contributor and has made a world of difference in terms of timelines. It helps spin up our Practice Management systems in a very quick time frame.

The ease of adding additional servers is valuable. We have a portal that we can go into to add those new servers, and then outside of that, the overall time that it took for disaster recovery simulation is also good.

They are doing a lot of great things, but I have heard that Zerto is expensive.

I have been using Zerto for two years.

I would rate it nine out of ten for stability because we had one virtual machine that was not backing up properly, but we did work with support. We got phenomenal support. They helped us fix it.

I like the scalability. Because we are in the acquisition space, we wanted adaptability. As new engineers are coming in and adding more to our data center, they can go through and they can just add it to Zerto. That is a part of their process. 

They are fantastic. I would rate them a ten out of ten.

Positive

We had a different platform previously, and we swapped it with Zerto about two years ago. 

We had Commvault. We were not getting consistent backups. We were not getting consistent disaster recovery. Each of our simulations did not match up, and nothing made sense.

I would rate Zerto a ten out of ten in terms of speed of recovery versus other solutions. 

It was super easy. We did partner with Verinext to come in and help implement it, so the swapover was instantaneous. It was super quick.

Our experience with Verinext was fantastic.

We have seen an ROI. We had an outage in our data center, and we were able to use Zerto to spin up in Colorado to be able to continue to operate, which is multi-million dollars at 450 animal hospitals.

I have heard that it is expensive, but that is not my world.

N-able was a solution we looked at, but it did not fit our needs. We had previously been using Commvault, and then we found Zerto. Our solutions partners were the ones that recommended it to us. After we saw what it was able to do, we made the swap.

If someone is considering Zerto, I would advise them to go ahead and swap to Zerto. I would share my entire experience with it with them and how it has been phenomenal for us.

I would rate Zerto a ten out of ten because of the recovery time.

We use Zerto to protect our centralized environment on our data center.

We implemented Zerto to ensure our environment keeps running in the event of power failure or hardware issues.

Zerto is extremely easy to use.

The near synchronous replication is powerful and eliminates the need to use other storage solutions. The near synchronous replication is important for the services that we are providing.

It has drastically reduced our downtime. Previously, recovering from an issue took three days, but now with Zerto, we're back up and running in about an hour, minimizing disruption and keeping our business operational.

The continuous data protection has transformed our IT operations. By enabling us to restore our entire environment and resume functionality within hours, it eliminates the multi-day downtime we previously experienced in recovery situations.

Zerto has significantly reduced our operational costs and time commitment by 90 percent. Compared to our previous solution, Zerto requires fewer resources and allows us to complete tasks much faster.

Zerto safeguards our virtual machines, ensuring critical applications recover in minutes while less essential ones are restored within hours. This significant improvement replaces our previous recovery time of two to three days for the entire environment.

It has reduced our downtime by 85 percent.

While we hadn't previously tested our disaster recovery plan, our current backups and improved recovery time give us greater confidence in our ability to respond to an incident.

Zerto strengthens our IT team's disaster recovery plan by boosting their confidence in the system's reliability. With Zerto, the system can now recover quickly from the biannual power outages that used to cause instability, thanks to its improved stability within the failover environment.

The most valuable features of Zerto are the ease of use and recovery speed.

The most valuable feature for enhancing our data protection strategy is the ability to test and validate that the protection is up and running when we need it.

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.

I have been using Zerto for one year.

I would rate the stability of Zerto nine out of ten.

I would rate the scalability of Zerto nine out of ten.

The technical support team was responsive and effective in resolving the small number of problems we encountered.

Positive

We used to rely solely on Veeam for backups, but now we have a layered approach. We still perform Veeam backups for long-term data protection. However, we've added Zerto for disaster recovery, enabling much faster recoveries of our critical systems in case of a major outage. This way, we have both comprehensive backups and the ability to get our key functions back up and running quickly.

Zerto boasts faster recovery speeds than Veeam and offers a significantly easier testing process.

The deployment was straightforward. It was completed by one person in one day.

The time Zerto saves us restoring our services provides a significant return on investment.

I would rate Zerto nine out of ten.

Our Zerto deployment spans multiple locations and is managed by a team of eight administrators who are responsible for protecting 30 virtual machines.

While Zerto itself doesn't require regular maintenance, it's important to conduct periodic tests to verify our disaster recovery functionality and generate reports to monitor its health.

I would recommend Zerto because it provides better and more simplified protection.

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.

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.

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.

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.

I have been using Zerto for several years.

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

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

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.

Positive

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.

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.

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.

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.

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.

We use Zerto for disaster recovery and cloud migration.

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.

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.

I have been using Zerto for four years.

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

Zerto is scalable.

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

Neutral

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

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

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

I would rate Zerto an eight out of ten.

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

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.

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. 

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.

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. 

I have used Zerto for about five years.

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. 

Positive

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. 

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.

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.

We primarily use Zerto for disaster recovery and business continuity. We have also used it significantly for transferring workloads between different environments.

Zerto's Near-Synchronous Replication is very important and was one of the main factors that drew us toward the solution. Some of the other solutions now have a similar feature that wasn't available before or doesn't support RDMs that we use. Fortunately, we haven't been hit by ransomware, but if we ever were, Zerto would be a great help. The fact that we would be able to easily pick a point with minimal data loss compared to having to go to a backup is a major advantage. 

We have definitely been able to do some functions that we wouldn't have known how to do without Zerto. For example, we get hardware refreshes every so often. We are still using Dell VxRail, but for some of our clinical workloads, we created a new cluster for PACs and radiation oncology. We had to move many workloads from Dell VxRail to this dedicated cluster, which was traditional SAN. Zerto saved us in this situation, as we were able to start a VPG and move the workloads. Additionally, we have different data centers, and if someone decided they wanted the workflow to run in a different data center, Zerto saved us a lot of time by not having to rebuild the system. Lastly, it gave us the ability to test failovers with staff to prove that it would work before we had to trigger a live migration.

We primarily use Zerto to protect our virtual machines.

Before we found Zerto, our backup environment was so slow that it could take multiple days to recover certain servers. This was not practical, so we looked for a better solution. Zerto has had a much greater effect on our Recovery Point Objectives than we could have achieved with any other solution before it. We could have potentially lost a day's worth of data, whereas with Zerto it is only a matter of a few seconds. Therefore, for any critical workload, Zerto is the best choice.

Our only other option was to recover from a backup. We found that for larger VMs, it would take days to do that compared to using Zerto. Zerto would spin up in a matter of minutes, and with the recording running through testing, we had the actual times recorded that we could accomplish all the tasks. It was drastically different.

Zerto has helped us reduce our DR testing. Before Zerto, we never had a DR test plan. It is still a work in progress, but Zerto makes it much easier to test functions as we can get reports on the test runs. This makes it easy to hand over to someone explaining the details of how long it took. Whenever we have done testing, it has been easy to perform and not very time-consuming.

Zerto's ability to test failovers with a record of how long it takes to fail them over is beneficial, as it allows us to know the timing in the event we have to do it live. Additionally, the support and RDMs, which many products do not have for this type of workload, are useful. Furthermore, the ability to easily move something between different sites and the general ease of Zerto is great.

Zerto's ease of use is the best I've seen. We initially looked at different options such as Veeam Backup & Replication and VMware SRM, but Zerto appeared to be the most straightforward. We have had other options come up since then, but they are not nearly as user-friendly as Zerto. Zerto is quite straightforward.

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.

I have been using the solution for over five years.

Zerto is stable and we have never had any issues.

We have not increased our original purchase, but Zerto would scale if we needed it to. As new projects came along, we were supposed to identify if Zerto would be a use case. We have enough licenses for everything that has been added so far. We do eventually want to go into the cloud and potentially add more workloads, and Zerto seems to be sufficient for that.

I always find the technical support to be quick in responding to us, and the issue seems to be resolved almost instantly. It has been nothing but positive with support. They are definitely one of the better companies to deal with in terms of support.

Positive

The initial setup was straightforward. We had someone from Zerto come down and set up the system in just a few hours. They provided us with knowledge transfer on how to create VPGs and other items and gave us an overview of the architecture of the whole solution so that we were confident in managing it ourselves. We have done all the updates ourselves.

The full deployment including the planning phase took a couple of weeks and required a few people.

The implementation was completed in-house with the help of a Zerto specialist.

Zerto has been more of an insurance policy. We haven't had to use it yet, but if that day ever comes, it will be invaluable. Zerto has already helped us in other areas, such as moving workloads, which has saved us a lot of time that would have been spent rebuilding and decommissioning. more of a safety net.

We do renewals and haven't added any additional licensing yet. When we purchased Zerto, we felt it was worth the cost as it would protect us from any potential problems and give us peace of mind knowing that any critical items could be recovered quickly.

I give the solution a ten out of ten.

When we bought Zerto, our goal was to be able to failover to the cloud. However, we have not yet fully adopted the cloud, so we have not yet upgraded our license or paid any connection fees. Our goal is to upgrade the license once we are ready, but that has not happened yet.

Zerto's ease of use, and straightforward use, is the reason we chose it over other solutions. We don't want to be in a situation where, during a crisis, we have to hunt around and try to figure out how to use something. It's nice to have something that is straightforward and easy to use, instead of adding stress to an already stressful situation.

We are still using other products for backups. We have not really ever used Zerto for backups. I know Zerto has changed its licensing model, but when we initially started using Zerto, we had to license every VM for basic protection, which was more costly than other backup solutions. I know Zerto has changed and we can now buy a backup license for VMs. However, due to the time, we are locked into a certain backup product, we will look at other potential solutions when the contract expires.

We have Zerto deployed across two of our data centers.

We have one person that maintains and monitors Zerto with an additional person who acts as a backup.

The maintenance consists of updates and tweaking of journals for VPGs.

If we have any specific use cases that we want to discuss with the Zerto team, they will often arrange a peer meeting with organizations. Zerto did that for us when we were using Meditech MAGIC so that we could make sure that anyone else with experience running it could help us. We were able to do a trial run with Zerto to get confident. I suggest taking advantage of doing a trial to make sure Zerto meets our needs, and if we have any unique workloads, then talk to the Zerto account team to try to arrange a conversation with someone else who is doing the same thing.

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.

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.

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.

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.

I implemented the solution back in the fall of 2016.

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.

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.

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

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.

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.

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.

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.

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

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.
