HPE Zerto Software Reviews

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.

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.

Implementing failover to a secondary data center is crucial for ensuring business continuity in the event of primary data center loss. This strategy involves automatically redirecting operations and services to the secondary data center when the primary one becomes unavailable. This not only minimizes downtime but also enhances overall system reliability. 

The failover process requires robust synchronization mechanisms to ensure data consistency between the primary and secondary data centers. Regular testing and monitoring are essential to validate the effectiveness of the failover mechanism and identify and address any potential issues proactively. 

In summary, failover to a secondary data center is a strategic measure to safeguard against disruptions, offering a resilient solution for maintaining seamless operations in dynamic and challenging environments.

Zerto has significantly enhanced our organization's resilience and data protection capabilities. Its real-time replication and failover features have played a pivotal role in minimizing downtime during unexpected events, ensuring business continuity. 

The platform's automation and orchestration capabilities have streamlined our disaster recovery processes, reducing manual intervention and accelerating recovery times. 

The point-in-time recovery options provided by Zerto have proven invaluable in mitigating the impact of data corruption or accidental deletions. This has bolstered our data integrity and provided a safety net against unforeseen data-related issues.

The live failover tests and point-in-time recovery options have been exceptionally valuable features of Zerto for our organization. Conducting live failover tests allows us to validate the effectiveness of our disaster recovery setup in a controlled environment. This feature ensures that all components are in place and functioning as expected, providing confidence in our ability to respond to real-world disruptions. 

Additionally, the ability to choose a specific point in time for recovery down to the seconds is crucial for data integrity. This granular control allows us to roll back to a precise moment, mitigating the impact of data corruption, accidental deletions, or other unforeseen issues. It adds a layer of precision to our recovery process, minimizing potential data loss and enhancing overall resilience.

The product could benefit from improvements in automation, specifically in the area of failovers. Currently, the process is largely manual, and introducing automated failovers after a certain time threshold would enhance efficiency and responsiveness. Automated failovers can reduce the dependency on manual intervention, allowing for quicker and more proactive responses to disruptions. In the next release, the inclusion of scheduled or automated failovers would be a valuable addition. This feature would empower organizations to set predefined parameters and triggers for failovers, ensuring a timely and automated response to potential issues. It not only streamlines operations but also adds an extra layer of reliability to the overall disaster recovery strategy.

I've been using the solution for six months.

We did not have a solution before.

We had great help from the company in terms of setting up our environment.

We implemented through a vendor; I'd rate the experience ten out of ten.

Anything is the worth the cost for virtually no downtime. Time is money.

We did not evaluate other options.

It is a great solution overall, however, it could use some upgrades with automation.

We utilize the solution for our primary backup and recovery source. We use VMware for all of our servers. 

With the ease of integrating with our complete virtual infrastructure, it is nice that we can replicate easily between our HQ and DR sites. 

The flexibility in utilizing the test environment to allow production servers to be test restored with no interruption to the actual production server in use is really nice for quick and efficient testing. 

I highly recommend it for companies using virtual infrastructure.

The product allows us to restore to any given point within 15-20 second increments, including just files and whole servers. 

It allows us to efficiently test restore and restore files that were accidentally deleted within seconds of the deletion, giving the option to have the most up-to-date file restored with little to no data loss. 

It also allows reporting on the results of the testing, which can be provided really easily for board reporting, as well as auditing. There are many great features for sure.

The LTR function has by far been the best feature to allow us to retain our backups for at least a year. Also, it allows us to have full monthly and weekly incremental backups for that year, which can be restored or even just files from that period. It has come in handy for those accidentally deleted files. 

It also helps us keep our required retention period for specific documents and allows us to recover older documents if we have to compare and recreate those.

We would like the LTR function to be able to retain the past 12 months. Before the update to version 9, we could do this in the GUI. I am hoping that in version 10 (which is on the roadmap to be installed), this feature will return in the GUI to provide an easy way to lengthen our retention. The journaling can also be a problem at times. Also, I'm not sure why, however, retention processes randomly fail and have to be rerun periodically.

We have been utilizing this solution since 2017.

We use Zerto to verify the information being transferred from one data center to another.

When a site is down, we can continue to use the other site thanks to Zerto.

The near-synchronous replication is extremely valuable because it ensures we can continue working.

The move action between the app and data center is great and we can see the benefits in minutes.

Our RPOs are performing well thanks to Zerto.

Migrating data using Zerto is easy.

Zerto helps our users collaborate during data migration.

Our RTO using Zerto is good.

The communication between the VM and the secondary data center is the most valuable feature.

I would like Zerto to provide more detailed information when there is an issue.

I have been using Zerto for five years.

Zerto is extremely stable. 

Zerto is scalable.

I have used the technical support of Zerto several times and they are good.

Positive

Though I wasn't part of the initial deployment, the procedure is relatively simple. Manager rollout is the first step, followed by CPG installation on VMs by the CPG teams and subsequent network configuration verification.

Four people are required for the deployment.

I would rate Zerto a nine out of ten.

Zerto is a good solution for transferring data between centers.

We primarily use Zerto for disaster recovery.

Zerto ensures a smooth transition during a disaster when we need to automatically switch from our primary environment to our recovery one. Zerto offers us disaster recovery in the cloud, which is essential because we don't need to pay upfront costs for infrastructure when doing the DR process. Zerto helps to protect our VM-based applications. 

The solution has also reduced our RPO. The RPO during testing was less than 15 minutes. Zerto reduces the amount of work we need to do because some of the steps are automated. It takes about five to 15 minutes to test. Zerto has decreased the number of staff needed for backup and DR. It only requires one or two. 

The core backup and disaster recovery features are the most valuable. The near-synchronous replication ensures we will be able to keep the business running if something happens. 

There's a mandatory VMware version, so we need to update our VMs in order to access our data. Zerto should work with all VMware versions. 

I rate Zerto nine out of 10 for stability. 

I rate Zerto eight out of 10 for scalability.

I rate Zerto support eight out of 10.

Positive

We are using Zerto and Acronis. 

Our IT team handled the deployment, but I don't think it was complicated. 

Zerto is a little expensive.

I rate Zerto eight out of 10. 

I used Zerto in my last company for disaster recovery. It was a hospital, and now, I work for a bank where we use it for both disaster recovery and migration. We are doing a major migration.

Currently, we are doing disaster recovery only on-prem, but down the road, we will also go to the cloud. We are planning to go to Azure, but we do not know what we will actually use at that time.

We can recover a VM at any point. It probably takes five minutes, which is very important for us because if I lose my active node, I will have my production up in a couple of minutes.

We did reduce the migration time. I do not have a number, but it is better than VMware SRM. We are a big VMware shop, and we have now started buying HPE.

In terms of Zerto's effect on our RPO, I do not have the numbers because I am an implementation engineer, but the numbers should be good.

The migration and ease of use are valuable. It is easy to set up and easy to flip. We just need to click on Move. It can Re-IP at the same time. This is something very useful for us. Disaster recovery is also valuable. 

Its user interface is good. I have no complaints. The only complaint is that if I remove a host from a cluster, it does not like that. If I move and put the host in maintenance mode to fix it, and vRA is down, Zerto does not like it. Zerto should figure out that this host has an issue and it went down. Zerto should then let me upload that vRA information to another vRA.

So far, we have not seen any issue. We will know more down the road as we use it more and more, but right now, we are okay.

It is very scalable. That is why we did not go for Veeam. We went for Zerto.

Our environment is very big. I work for a large bank. 

I have not yet called their support. I did not have to call them.

We switched from VMware SRM to Zerto. VMware SRM is good, but if I do not do error-level replication and I do only vSphere replication, it is not good. The vSphere replication is not as good as the Zerto replication. Zerto is faster. It takes less time.

I did not do the implementation, but my team deployed it. Because I have used it before, my guess is that it is not complicated to deploy.

We have seen an ROI. If I do a vSphere replication from vCenter to vCenter, and of course, we can do long-distance vCenter migration these days, it would not be as good as Zerto replication.

There is a lot of confusion with Zerto licensing. They have a migration license and a replication license. They should simplify the licensing process. 

The migration license costs a lot of money, and it is only on a one-time basis. If you use that license, it ties to that VM. I might re-migrate that VM in the next five to ten years. It is another environment, but my license is stuck there. 

The replication license is fine, and I have no issue with its pricing model, but they should simplify the migration license. It should not be tied to a VM. They can reduce the price because a lot of people do not buy it because of the price. A long time ago, Double-Take Software used to do what Zerto is doing now. It is another replication software.

I was not in that group, but they did test Veeam. I also used Veeam in my last job. I am not sure if I am qualified to compare, but Veeam seems to be for a small to medium company, whereas Zerto is an enterprise software.

Overall, I would rate Zerto an eight out of ten because we do not yet know everything.

Our primary use cases include replication and disaster recovery. 

We use Zerto to help protect VMs in our environment. We are really happy with RPOs (Recovery Point Objectives).

Both the Recovery Point Objective (RPO) and Recovery Time Objective (RTO) are fine. They always meet our requirements. Their significance is not driven by a single factor but rather by the customers. Some customers require an RPO of a few hours, while others require up to 24 hours. It depends on the specific needs of the customer.

The most valuable feature for us and for my company is that we are replicating most of our production customers to the DR site, and we can do testing whenever we want. The customers are very happy with the way we do the testing while the primary is still running. There's no disturbance to the primary production site. 

The most important function right now is that we have another DR site, which is in a very old environment that is non-Zerto. We were log shipping there through another method. We are migrating over to the Zerto platform so we can replicate it to the new DR site so we can shut it down. That's going to be a lot of savings for us, shutting down the old replication with the other way. That will be one of the benefits too.

Zerto offers near-synchronous replication, which is always on and constantly replicates only the changed data to the recovery sites within seconds. It doesn't really bother us because we have enough bandwidth. Since we do a 24-hour recovery, it does not take a lot of disk space. It's an issue sometimes because I have to constantly increase the space on the disks at the DR site. On the VPG (Virtual Protection Groups), I have to constantly increase the space. That's where the alerts are being generated too.  

Someone suggested to me that I should turn off this feature, but that's not the way to do it. Turning it off temporarily is similar to applying a bandage.

Moreover, we have plans for DR recovery in the cloud. That's our next step, and it's likely to be on the agenda. We probably will use the license we have for that, which we can use as of today.

Zerto generates many false positive alerts, which is annoying. I still have thousands of alerts in my inbox, and those are false alerts. When I check there's actually no problem.

I have been using Zerto for four-plus years. 

It's very stable as far as we're running. Even though I'm running it on a very old Windows Server 2012 server, it's still running fine without any issues. 

Scalability-wise, it's pretty good, too, but we're not there yet. We are using it for small 50+ VMs we are protecting right now, but we are continuously growing. We may have to expand with multiple ZVMs (Virtual Managers). We're going to install multiple. We just have one on each side, which we don't have an issue with.

The customer service and support are really good. I wish they had phone support too right away, but we have to go through their website and open a ticket.

Moreover, there's always going to be something a person is not one hundred percent knowledgeable about. He has to escalate to the top tier. 

Positive

Somebody else did the deployment in the company and I took it over after that. I just recently upgraded to the latest version without any issues. Zerto is very easy to upgrade.

There is an area of improvement for Zerto folks. Every time we do an upgrade, if we are three or four releases behind, we have to go to the next level, then the next level, and then the latest. This is a pain. We would like the ability to skip to the newest version. 

ROI is pretty good compared to the recovery compared to the investment we have. The solution is worth it. If we go to the cloud, the ROI is definitely going to be much more.

The pricing is pretty decent. We got a good deal. 

I really like Zerto. I've been using it for many years. It's a quick recovery. I failed over the complete site to the DR many times and then failed back to the production without any issues. 

We have VMware SRM but we are not using it. We have a license, we can use it, but we're not using it because Zerto is our primary right now. 

Zerto is very easy to use. It's not dependent on the hardware. It can decouple from any hardware. You can use it, even if you have different hardware at the source and the destination. That was the biggest attraction when we got into Zerto. It's pretty decent. 

I would rate Zerto a ten out of ten.

We use Zerto for server migrations between data centers during the role swap that we do. We use it from a recovery standpoint as well.

We currently do not have disaster recovery to the cloud. We go between our data centers. That is what Zerto helps us accomplish.

Zerto works very well. We have not had any faults while using it. We are a financial institution, so we have to make sure the systems we have are available with very minimal downtime.

It has helped out a lot in man-hours. It has saved us a lot of overnight work. We can literally change our production servers in a matter of minutes to hours. Rather than having to do this gradually or a couple of weeks in advance and have several teams and business partners involved, we can literally do it live on the same day.

Zerto is probably one of the faster ones in terms of recovery. You can just go into the console, and because it is always replicating over to the other side, it takes minutes.

Being able to do our recovery and being able to migrate between data centers during the role swap is valuable just because of the amount of time it takes. It takes 55 hours or so. Right now, we are doing this in a VDI environment. We are going to experiment with it as a proof of concept because we have a thousand machines that we have to move and do all the assignments. Zerto would lessen that down by a few hours, and then we can use some scripts to do everything on the Horizon's side. We have not done it yet, but we are hoping to reduce it down to about 3 hours instead of 55 hours. We will also be able to manage our host better and be in a better recovery state. If the host happens to go down, we can quickly recover.

It is very user-friendly. There is no wondering about what a feature does. It is easy to use.

If they already do not have it, they can have some APIs for the Horizon environment. Instead of having to use some scripts to get around, they can make it a lot more user-friendly for integration.

We have been using Zerto for two years.

It has been very stable. We have not had any issues while using it. When we need it to do its job, it is always dependable.

It scales very quickly. We can set up a whole new environment in an hour. We can get the server setup and all the VMs that are required for it to function in an hour or two.

I have not used their support. My peers had to use it. They seem very responsive and knowledgeable. 

The other DR tool that I have used is from Symantec. It was an old-school recovery tool. It was back in the day when it took a whole day to get things back up.

It was deployed before I joined the company.

Its price is fair. It is very cost-effective compared to the cost of the labor for your workers and associates. 

We selected Zerto over others primarily for the ability to replicate and help with our role swap. It cuts the downtime of the production systems by a large volume. This way, we can meet the deadline and not have that much client impact. In the financial side of banking, you do not want bad performance.

I would rate Zerto a nine out of ten. There is always room for improvement, but it definitely makes your life a lot easier.

We are using Zerto as a DR solution for our environment as well as for migrations. When we do data center migrations, we use it to move our servers over.

We are only on-prem at the moment. We do not do disaster recovery in the cloud.

In the old days, during data center swaps, it used to take days to move our workload environments over, whereas now, it literally takes an hour for hundreds of servers to migrate. Literally, in under a minute, an app stack can move down and up in a new data center. It is reflected in the uptime support to our customers. Our company is very happy with the product.

Essentially, you just tell it to go and pull the trigger. It is all automatic, so you can sit there and watch the shutdown within vCenter, and then on the remote side, you can see it coming up. You can literally have your environment up and running in under a minute. You just have to prioritize what goes first, and that is a business decision.

Its automation and the ability to replicate and keep an RTO of just seconds is valuable. It is all automatic. Everything is pretty transparent on the backend. It is just point-and-go.

Its near-synchronous replication is amazing. It is a lifesaver. You can see it replicating in real-time in seconds. The overall impact on the network is negligible as well. It is a great tool.

From the technical side, there can be a little bit more PowerShell integration. I know it leverages APIs, but people still use PowerShell. Some people would rather use PowerShell if that is an option.

I have used it across several employers. I probably used it for a total of four or five years before it was bought out by HPE.

It is amazing. You just look at the dashboard, and it is pretty much all green unless you have some replication or journaling issues, but that is not the product's fault. 

Scalability has not been an issue. You deploy it, and it just ramps up and goes. It is all in the background and automatic.

We have about 700 servers and 130 VPGs.

I would rate them a ten out of ten. They are very responsive and technical. Even when there is no issue and you are looking for a root cause or just a question, they are very responsive. They exceed their SLAs.

Positive

My current employer already had it in place. In my previous role, it was evaluated against a few other competitors, and it ended up being a replacement for VMware's Disaster Recovery, which at that time had a lot of issues. Zerto came in and helped us out. We implemented a few new things that Zerto did not have, and I have not looked back.

Zerto is easy to use. I would rate it a ten out of ten in terms of ease of use.

Currently, we are still on version 9. We have deployed that. Overall, it is very easy once you get the Windows Server. I am excited about the new version 10 coming out that takes away the Windows server requirement.

We did not use an integrator or a reseller, but we are in contact with our engineer from Zerto. I personally know him from a previous job and as a friend as well. If I have questions, I am sure he will help me out.

Uptime for our customers is important. When we are able to do transitions and not impact customers or minimize that impact, that is a financial gain at the end of the day in terms of the satisfaction that customers get, as well as the overall view of the company. As a whole, the management sees that we are doing this stuff in minutes and hours versus days. So, overall, the company is not looking to move away from Zerto anytime soon.

I know it is per server, but I am not fully aware of the price model. I know for our VDI environment, they are looking at something that is on the lower end and that they can use just for migrations and not so much a disaster recovery.

I would rate Zerto a ten out of ten. It scales well. It just works. It is amazingly simple. Everything is pretty much automatic. I cannot remember when I had to open a case because Zerto was not working.

We use the product solely for disaster recovery.

The solution has helped with zero data loss from a transactional perspective. We have about forty servers in there today and they all serve a core function for our business. With Zerto, it's a matter of just being able to achieve zero data loss in minutes in terms of recovery time. That's amazing, and it really enables our business from a disaster recovery perspective.

The key benefit for us, and why we transitioned to Zerto years ago was really the recovery time. We went from hours to days on some of these applications, to minutes.

I like the granularity of the checkpoints. That's been extremely beneficial for us in testing. The near synchronous replication of Zerto is great. Knowing that it's within seconds or minutes allows us to achieve our goals from an RPO perspective. 

I like the live failovers. 

It's also a very easy-to-use product and very easy to administer from just a time perspective. 

We're able to stand up our DR site within an hour if we need to. 

We've been able to use it to do kind VM migrations from site to site in the past. Just it doing it behind the scenes allowed us to dramatically reduce any downtime for private cloud to a private cloud or even on-premise to private cloud migrations.

When handling migrations, it's fairly intuitive. There's a progress bar with percentages. Sometimes the timing fluctuates based on bandwidth. However, it's going completely in the background. It doesn't interfere with anything. When you are live, you can cut over with minimal downtime.

It's improved our RTOs. It's dramatically improved RTOs compared to what we had before.

We've had multiple unplanned failovers and the solution worked as expected. It's probably saved us 24 hours per instance.

The product has reduced the amount of staff involved in data recovery situations. Before the solution, we had two or three different mechanisms for different types of systems in different applications. Now it's just one click, one interface, and one administrator. 

When we do failover and failback, it doesn't maintain some of the settings that it should and I don't really understand why that happens. Quite regularly, anytime we do a failover or a fallback, we have to confirm all the settings for each VM. That takes a little bit of time. There is some power shell for that, so we've been able to automate that or at least optimize that. That said, that's my only complaint. Maybe that's a VMware limitation. I'm not sure.

We've been a customer of Zerto for several years. We started using it around 2017 or 2018.

The stability is good. Of course, from a maintenance perspective, sometimes with the failover, we have to re-sync or set up the settings again for whatever reason. I'm not sure if that is a limitation of the product or a limitation of VMware. 

We have six or seven users that use the solution, and typically just two or three administrators. 

We've scaled in that we have increased our VM count or VPG count. However, if we had thousands of VMs, I'd question the RTO or RPO capabilities at that point. However, ours is fairly small, under 40 VMs, and it has worked well for us. 

Technical support has been great. In our last DR failover, we needed to put in an urgent ticket and we got a very prompt response on that. Based on my interactions with them, by far they have the best support. 

Positive

We did use other solutions before, however, they were not as comprehensive as Zerto. We moved to Zerto so we could get our RTO and RPO down to minutes. Just being able to do everything with one administrator makes it much easier than before since we were doing some things from backups.

From a desk disaster recovery perspective, Zerto has replaced all legacy backups. From an administration and time perspective, we're definitely seeing some savings there. 

The initial deployment was not very straightforward. We were able to deploy in a matter of hours. The foundational aspects of Zerto are pretty easy, however, managing VRAs and getting the replication going can be a bit more work.

For the initial deployment, we only needed a single administrator. 

The solution definitely requires maintenance, just to keep everything up to date. However, it's very intuitive and everything happens very quickly, based on how many VRAs you have. We have three administrators capable of managing Zerto as needed. 

We have three sites, either on private cloud or on-premises. They are all VMware-based. 

Initially, a consultant assisted us with the base installation.

We have not calculated the ROI of the solution.

I was a little disappointed this year with the pricing, especially being a legacy customer of Zerto. 

They changed the licensing structure as a result of the HP acquisition. We had a significant increase that was not very well communicated to us and wasn't planned for us and it hit us pretty hard. From a budgeting standpoint, we only got notified a couple of months before, however, we were already in our calendar year. We couldn't plan for it properly due to the timing. It was frustrating for us. The costs were up significantly for us this year. That is definitely something we will be mindful of and keep an eye on going forward. We may need to find an alternative if the costs keep increasing.

We did explore other solutions, such as VMware and other competitors. However, the ease of use and ease of implementation were good selling points and became a key deciding factor for us. 

We have not used the immutable data copies as of yet.

In terms of dealing with threats or attacks, I've read a lot of the white papers, however, we haven't really had to have a need or a use case for that at this point. We're aware of that functionality, however, we haven't had a need to really utilize that, thankfully.

It took us a while to realize the benefits of the product. The initial phase for us was to cover about twenty different servers, which had interdependencies within the application. It was quite difficult. It took us about a year and a half to fully utilize our application or our initial phase of productivity. That said, that wasn't a Zerto limitation. That was the fact that we were changing IP addresses between our sites, so it was more of an application configuration delay. Zerto was ready to go on day one, basically.

We don't use Zerto to support disaster recovery on AWS. We're strictly on-premises hypervisors. We use virtual machines.

We haven't used Zerto's data recovery testing functionality. 

I'd advise new users to utilize the failover testing. You really have to make sure the application functions. Within our use case, for example, we have very interdependent applications. Each piece requires lots of communication, lots of databases, lots of other application transactions that are interdependent, and lots of integrations within our application. Utilizing the failover testing was critical for us.

I'd rate the solution eight out of ten.
