HPE Zerto Software Reviews

We've been using it to consolidate data centers. We have 13 hospitals and two main data centers and a cloud presence. We're trying to collapse everything. We've been using Zerto to move the workloads over to our primaries.

It's allowed us to save a lot of money by collapsing a few data centers. We have been able to evacuate the hardware in the one data center in our virtual environment, and then shut down and get rid of all those hosts. And it has saved us time in our failovers, from collapsing data centers to our primaries. It enabled us to do that on the fly.

One of the valuable features is the ability to re-IP on the fly, because it makes the migration a lot smoother on the system end.

The syncing of the replication needs improvement. My experience has been that, every once in a while, when you go to do a failover, it tells you it's not syncing. Then you have to troubleshoot and figure out why it's not fully synced up.

I have been using Zerto for three years.

It's pretty stable.

I've never had to use the technical support.

We use VMware SRM pretty exclusively for our disaster recovery stuff. SRM and Zerto are very similar in the way they work. Zerto enables features that SRM doesn't give us and that's why we purchased it.

Also, it takes half as much time to failover with Zerto as it does with SRM. Every six months we do a failover of our Epic environment from one data center to another, and we use SRM for that. We've been using Zerto for failovers from one data center to another for data center consolidation, and those seem to happen a lot faster than SRM.

We've definitely gotten our money's worth out of it for what we've been doing. We have been able to close three data centers so far.

We looked at Veeam, but that was a long time ago.

We use Zerto as our primary disaster recovery tool for our most important servers.

Zerto is tremendously valuable. It is the backbone of our DR solution for critical databases that hold the data we can't afford to lose. It provided new opportunities to change how we approach disaster recovery. 

We realized the benefits quickly, but I don't think it became a staple of our disaster recovery until about a year into our deployment. In the first couple of months, we had some hiccups with upgrades. Once they sorted everything out, it truly became a core solution for us.

It enabled us to transition from data recovery based in a physical data center to the cloud and protect VMs in our environment. Our RPOs also improved tremendously. When we first started, only one other product offered the same RPOs that Zerto provides. However, the other product was problematic, and Zerto has been solid. Compared to other DR solutions, it works quickly to stand up the failed server at another site and bring it nearly into full production. 

We used it to migrate a server, which provided a wonderful recovery time. It worked well. Our RTOs improved tremendously. It reduced downtime in most situations and the time spent on DR testing. A DR test used to run probably 48 hours and involved around four engineers. With Zerto, it runs for about six hours and only requires two engineers.

We couldn't find a product that provides the near-zero recovery point that Zerto offers. The closest we could get was another product that had zero data loss. Everything else had a minimum of 15 minutes of replication time, resulting in data loss.

Zerto can also perform test environment restorations that don't affect production. It's also easy to use. It's a set-it-and-forget-it product. Unless you need to make changes to the devices you protect, you don't need to go in except to make sure everything runs smoothly.

I wish Zerto had better file restoration capabilities. We have not been able to use that because of the limitations of Zerto's de-duplication technology. When we used the immutable data copies feature, we had some lag in replication times, so we don't use that anymore. When there is big data movement, it tends to cause some lag.

We've been using Zerto for about three or four years.

With time, it became a highly reliable and stable solution. We were an early adopter, and it had some hiccups initially. I think they've done a great job streamlining it and making it reliable.

The times that I've needed technical support, they've been very good.I would give it an eight.

Positive

Zerto still hasn't replaced all our other backup solutions, but it has replaced two of them. It is leagues above the other products we used in terms of simplicity and reliability. We have another solution to get around Zerto's file restoration and de-duplication issues. We use Veeam Backup and Replication for that. 

Setting up Zerto is straightforward. The documentation was great, and it is intuitive. Integration with VMware is seamless. It's good at running the scripts needed to run in order to work with VMware. We have a 90 percent virtualized environment. 

I think everything can be cheaper. Pricing limited our ability to use Zerto as much as we'd like, but that's not why we haven't adopted it as our primary backup solution.

We evaluated Double-Take, Veeam's replication solution, and Azure's Site Recovery. None could match Zerto's RTO and RPO. The only one that got close was Double-Take, but Double-Take was very problematic.

I rate Zerto eight out of ten. There's always room for improvement. It's one of the best solutions for disaster recovery available right now.

We use Zerto for disaster recovery (DR) purposes. We needed a tool to provide a quick resolution during a failure or problem and help us achieve our goals related to our service level agreement (SLA). We needed a tool that would help us in providing the availability of lost services within a specific time frame. We wanted to make sure that in case there is a problem and we have to execute the DR procedure, it is quick, easy, and safe. So, the main purpose for going for Zerto is related to meeting the required parameters for RPO and RTO.

We don't use Zerto for backup purposes. It is used only for virtual machines. We also have physical servers, but we have different tools for backup. 

Currently, we are using it for on-premise data centers, but we also do proof of concept tests with public clouds or hybrid clouds.

It is very good in terms of end-user experience and functionality. The graphical user interface (GUI) is quite simple, and it shows many values related to the status of replication. You can see the current status of a specific application and the health status of infrastructure on the GUI. You can very quickly navigate the application and find very useful information related to the health status of your infrastructure. You can see if the infrastructure is working fine and if there are any bottlenecks or problems that need to be verified by the IT infra department.

It helps us with standardization. It allows us to have a unified DR approach where with one tool, we can meet the DR requirements of different systems with different levels of DR criticality and classification. We have customers for whom the availability of a particular system is crucial for business, and this system requires a very high quality of replication. At the same time, they also have systems that are not as critical. For a unified approach to the DR process, it is better to use the same DR tool for all applications with different levels of criticality. Instead of using different tools for critical and non-critical applications, it is better to use one single tool and have a unified process. Zerto helps us with that.

Different types of integration allow you to provide the tool not only to specialist teams, such as infrastructure teams, but also to the end-users to perform activities like failover, system recovery, and system protection. Service portal integration and automation integration provide a big value in terms of DR activities. You don't have to wait for VMware specialists to perform the DR failover task. You can do it on your own if you have access to the DRaaS portal, for example. DRaaS portal is DR as a service that we have implemented in our own infrastructure, and it is a part of process improvement in our organization.

It has significantly decreased our RTO for failover to the full scope of an application. You can easily measure DR activities for a specific application. If you are responsible not only for your application as an application owner but also need to provide support to many customers at the same time, such a tool is very good. When you are responsible for delivering as per the SLA for RTO to many customers at the same time, it is very helpful because you can perform required activities automatically, and you can also perform them in parallel.

We are very satisfied with the achieved RTOs. We have specific requirements based on the service delivered values and SLA contracts, and by using the tool, we are able to fully meet RTOs for specific applications, a group of applications, or the whole scope of a data center.

During our DR exercises, we try to simulate the worst-case scenario where a complete data center is unreachable, and we are able to achieve the required RTO. Zerto is able to fully meet our needs, and we are able to achieve the required RTO during our normal and yearly DR exercise. We are receiving exactly what we were promised. However, I can't provide metrics or compare it to another tool because we have been using it from the beginning. I don't have the metrics for how much time it would take if we didn't have this tool, but the values that we are receiving during our annual DR exercise are fully satisfactory. So, it is fully sufficient for us.

The time saved in a data recovery situation depends on the specific scenario and the specific system that needs to be recovered. For example, if you have 50 gigabytes built into a machine that needs to be recovered, then with a traditional backup and restore solution, the recovery is very quick and easy. It would take from minutes to an hour depending upon your infrastructure or the bottleneck in your infrastructure. The problem occurs when you have very big systems with 10, 30, or 50 terabytes to be recovered. In such a case, it doesn't matter if it is ransomware or it is an infra failure. Even though the root cause is not the same, the outcome is the same. The fact is that you don't have a working system, and you need to recover the system. Recovering a big system with the traditional approach could take you a week, which is something that businesses do not accept. With a tool like Zerto, I can fail over the system very quickly. During DR exercises, I performed DR activities for systems with many terabytes of data, and it is not a problem to recover that system and failover. I have very good experience with that. During the training or presentation for my customers, I have shown how it works and what are its advantages. One of them is the possibility of a very quick recovery irrespective of the size of the system. The approach is exactly the same irrespective of whether it is an infra issue or a ransomware issue.

The main purpose of this tool is to allow failover between different data centers and different locations. When one site is unavailable, we can start the failover activity and perform the failover task. When a primary location is unavailable, or there is some hardware or logical issue at the primary location, it allows us to resolve the problem. We are able to start services at safe locations. We handle the disaster recovery process, and this is the main function for which we are using it all the time.

The second valuable feature is related to integration. If we want to implement any tool in our company, we want to make sure that it is not sandboxed. It shouldn't be completely isolated from other systems, and it should help other systems to receive feedback. To gain advantages of having tools like Zerto on the board, we want to combine our disaster recovery with other processes, such as incident management or change management. We can integrate these processes using different tools, but usually, the best approach is related to API. So, we can integrate different systems and combine them into a big IT platform, which allows us to achieve more features that are normally not available in the tool itself.

Zerto supports different ways to integrate with or get information from the systems. GUI is one of the options, and technologies like PowerShell cmdlets or RESTful APIs are also very good to exchange data for integration or automation purposes.

We also use Zerto for compliance purposes in case we need to provide evidence. When we perform DR exercises and we have some problems with the infrastructure, we need to prove that some actions were taken. It works very well when we perform DR activities and we want to show external auditors the proof and evidence of performed actions.

It is very quickly developed, and new features are provided quite often. I don't have any input for improvement or a critical feature request at this moment. If anything, a lower price is always better.

I have been using Zerto for six years. 

Its stability is very good. Of course, bugs can be found because this is live infrastructure, which is normal. There are new VMware releases, and there are new operating system releases. If there are some problems with applications, we raise cases, and we get the required support in resolving the issue. So, my experience has been very good.

Its scalability is very good. We can use it in on-prem and hybrid cloud environments. It works well with different vendors.

We are using it for different locations. We are using it for on-premise data centers, and we are also using it for all the production systems that we have. Any increase in its usage will depend on the decision of the company. If the decision is to change the platform and integrate with different vendors, we can choose additional features, but at the moment, we are using only the on-premises functionality.

Their support is very good. We have to meet our SLA, and the infrastructure is very sophisticated and demanding. We have had different cases that need investigation and resolution, and we could always count on Zerto's support, which is available 24/7. I don't have any complaints about their support. I would rate them a ten out of ten. If possible, I would even give them eleven.

Positive

I have not worked with any other tool previously. This is the only tool I have used. 

It was quite easy to implement and start the execution. There were no problems. It took us about three months to implement it in production.

For implementation, we were using the services directly from Zerto's support teams. In terms of the number of people, there were two people from the DR team and two from the infrastructure team, which included the networking and VMware teams.

In terms of maintenance, every tool requires maintenance, and when you upgrade, there are some bugs or issues that need to be resolved. Currently, for the maintenance of the application for many customers, one person is enough. Based on the number of protected systems and sophisticated infrastructure that we have, it works very well. It is not something that we should complain about.

Its price is reasonable. I have not worked with other tools, but as compared to its competitors such as VMware, its price is lower. So, in my opinion, its price is good.

Based on our experience and the implementations that we have done successfully, it is the right tool for protecting small environments and very big environments. It fits the needs of organizations that require a few functionalities, and it also fits the needs of organizations with a sophisticated environment comprising managed systems, multiple integrations, etc.

Zerto provides near-synchronous replication. So, the RTO is near zero. It is not equal to zero. From my perspective, there are some specific IT areas where synchronous replication is a must, but in most scenarios or use cases, synchronous replication is like a trap because you need to have a single connection between two replication zones or sites, which I would refer to as a single point of failure. If you have storage that is replicated between two sites, in certain scenarios, you won't be able to perform failover activities. If storage is broken on the primary location and you have enabled synchronous replication, the replicated data is also sent to the recovery site. So, you cannot perform failover activities because you now have corrupted data at both sites or data centers. We have chosen this tool to get out of this trap and be able to failover but not to the exact point in time when the issue occurred. I have experience working with such scenarios. For a specific group of systems that require synchronous replication, I can have an additional level of protection by having other DR tools, and at the same time, I can provide replication by using tools like Zerto. So, I can enable two DR solutions on one protected system and resolve the issues related to different scenarios.

In terms of reducing the DR tasks, because I have not used other tools, I can't provide the metrics for increase or decrease in time. However, considering that the tool is implemented for the whole scope of our application, we do not have to wait and spend weeks or months preparing for the DR test. We are prepared all the time for any issue. We also perform the unknown data center DR exercise allowing us to choose the test data center just before the DR exercise. I can very quickly start the recovery operations without a long preparation phase. This is one of the main features of a DR tool that should be taken into account for a company. You should have a tool that you can use at any time. You should ensure and be confident of the fact that it will work and not create any problems during the failover.

DR exercises generally should be performed by customers and application owners. That's because they know best what the issue is and how to provide a solution. It requires synchronization of some tasks and allowing more critical systems to be failed over before the less critical ones. To perform a global DR exercise preparation and execution, very less staff is required. Communicating with customers about the agenda and defining the scope, tasks, schedule, and other things take most of the time, but the execution phase is quick. It can be executed by one operator. It can be done by an infra specialist or an application owner, but ideally, it shouldn't be done by the specialist team. It should be done by application owners because they know the best about the issue.

I would rate Zerto a ten out of ten. It is a very good tool, and we have had very good experience with it. We have no problems with recommending it to others.

We've got two data centers, and for any of our applications that are not in some kind of a load-balanced or high-availability cluster, we use Zerto to replicate them, to make them as highly available as possible, without building that into the solution. We replicate between 100 and 150 different VMs from our North Carolina data center to our Chicago data center.

A small example of the way it's made things simpler is that we were building out a new product, and the original recommendation from the vendor when we were deploying that product was to have the application server closest to the end-users and the database server at our main data center in North Carolina. Once it was implemented, we found out that wasn't the case. We used Zerto to fail over the database to the same data center that the application server was in. We were able to do that really quickly and easily, without having to do a whole lot of extra work, such as having to rebuild the database server. That's one example of how we use Zerto, not just in a standard failover scenario. It made the process a lot easier than it would have been had we not had Zerto.

We have also used it when something happened to a configuration or a database file and it had become corrupted. It happened in the evening, after-hours. Rather than getting the backup engineer involved and trying to restore the files from a backup, we used Zerto to grab the file from a couple of hours previous, restored it, and got things back up and running really quickly. It's definitely a time-saver. We were able to handle it ourselves without needing to get anybody else involved.

One of the most valuable things about the solution is the ease of use when it comes to failing things over. The ability to easily test your failover capabilities is really nice. We can actually stand up a VM in an isolated environment, validate that the VM is up and running and that it boots properly, and we can do that in a matter of 30 seconds. Being able to show that to upper management, and that it's working the way it should, provides a lot of value.

It's one of the easiest products out there, as far as managing and using it go. The UI is pretty dead simple.

If everything is set up and configured properly, a failover of one or two systems can be done by one person. Nobody has to be involved other than the application owner, to validate everything, once the failover is done. It's a one-man show.

Continuous data protection is what it's supposed to do. Being able to bring a system up within a matter of minutes is the next best thing to having an actual high-availability cluster. If you're not building high availability into a solution itself, Zerto is the next best option. If we're talking about one or two applications or one VPG (Virtual Protected Group) a failover takes under five minutes, from the point of clicking "Start Failover" to the point of validating everything on the application end.

The only thing we've noticed that needs improvement is the backend cleanup within VMware. There are some little issues there. I would like to see tighter integration with VMware. From a recoverability standpoint, it's great when using VMware. But what we have noticed is that orphan data is an issue within VMware. It doesn't clean up properly when you're moving stuff around.

Our company has been using Zerto for several years. I took over management of it within the last six months, but I've dealt with Zerto in the past as well.

We've had no stability issues. We've had to open one or two cases on small issues, but they've been pretty trivial. There haven't been any critical issues with its stability.

It scales really well. Out of 500 VMs, we're using it for about 150 of them. That's probably not a lot compared to other Zerto customers. But as you add more ESX hosts to your environment, you just add new VRAs to the ESX host. There's not too much to have to worry about when you're scaling up.

We utilize it for everything that we don't build in a high-availability cluster. A lot of our stuff is designed as an HA cluster, but anything that is not designed that way is automatically protected by Zerto.

The technical support is as good as, if not better than, most of the technical support that we deal with. Opening tickets is easy. The support portal is easy to use. Depending on the severity—I've never had to open a Sev 1 case—Sev 2 and Sev 3 cases are answered within 24 hours.

Positive

We didn't have a previous solution.

I did not do the initial setup of the solution, but the upgrade from version 8.5 to 9.5 was very simple.

Our engineering team members, three systems engineers, are the main users of Zerto. We don't have segregated roles. I'm the point person for Zerto, and the other guys are backups for managing it and doing recoveries. Maintenance only requires one person.

We have seen ROI from a time-management standpoint.

I don't know if Zerto reduces the number of people that we need to have involved in a recovery scenario, but it definitely simplifies the process compared to using Commvault, which is our backup solution. If it's something that we need recovered from within a day or two, it's much simpler to recover that file with Zerto than it is from a backup solution like Commvault.

Anybody on our engineering team can probably recover a file using Zerto. I'm not so sure that's the case for Commvault. Our backup admin would probably have to get involved if we're doing a recovery from Commvault. Using Zerto, the UI is so much simpler.

There may be a small possibility that we will look at Zerto to replace Commvault whenever we do replace Commvault. That's a possibility, but it hasn't been brought up yet. We do know we are getting rid of Commvault at some point.

I've used other solutions, like Dell Avamar and Veeam. Veeam is definitely pretty easy to use and on par with Zerto. It's 100 times easier to use than Avamar. Ease of use is one of Zerto's strongest points.

Go for it. It's the best-of-breed for high-availability replication solutions. It really is dead simple to use and easy to implement and maintain. It's not one of those solutions that you have to spend hours a day managing. You look at it for five minutes a day and forget about it.

The biggest lesson I've learned from using Zerto is that high availability, having a good replication solution in place, doesn't have to be a big, complicated, scary mess. It can be simple. It doesn't have to be some huge hurdle that you have to overcome.

Zerto is our primary means of failing over our critical production loads that have a relatively low RPO/RTO. This is our use case for this solution.

What we like best about Zerto is its fast failover to another data center. It is simple and it works.

The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that we're only able to replicate one way using this solution. Now, we are evaluating the clustering of Zerto with Microsoft clustering, so we can replicate both ways and both data centers, and have the management server in both data centers.

Historically, Zerto has started going into the backup space, and that is when they lost focus on keeping their replication product good. Now, it seems they're finally leaving that backup space, and they're just sticking with replication, so in version 9, they have fixed all of my gripes about the product, e.g. they now support VMware tags, Windows bringing over the time on the target side, etc. All of these little things, they are all correcting, because they're now sticking with the replication product.

It's been five years since I started using Zerto.

Zerto is a single use case product and it works flawlessly. It is stable.

Technical support for this product was absolutely fantastic, but that was before they were acquired by HP. They are still good, but I can tell the company is becoming too big.

We didn't previously use a different solution, as this was the first use case or first requirement that we needed to have under a 24-hour RPO/RTO.

The setup for Zerto was very simple.

We implemented this solution in-house. Implementation only took less than a day to complete. Zerto was ready to use in our environment for a DR (disaster recovery) exercise weeks later.

The return on investment from Zerto was immediate. Instead of having legacy DR failover exercises that involved multiple teams and weekends work of activity, now a single user can fail over everything and get reports to prove that it was failed over and the data integrity was all done. As far as people hours and time, the ROI was instant.

Zerto is fairly expensive. We are on a perpetual three-year subscription, but for my less than 300 VMs that we needed this functionality for, it is worth it. I'm not aware of any additional costs beyond the standard fees for this product.

We did evaluate Commvault LiveSync, Veeam, and Dell solutions, though I don't even remember what the Dell product was. We did go through RFP. We went with Zerto because it was simple and it worked, and we didn't have to worry about doing anything else.

We're a Commvault and Zerto customer.

We are on Zerto 8.5, and we are evaluating version 9 update 3.

I have no impression on the scalability of this solution, because we haven't really grown yet. We have 300 endpoints and we've always been in that range. I can't tell how Zerto fares if there's more than 300 endpoints.

We have a primary asset owner who uses this solution, who gets feedback from other IT infrastructure teams of whether their servers need to have a low RPO/RTO. That single asset owner will then put those in Zerto. For deployment and maintenance, we have the primary asset owner, then there's a backup person. The primary asset owner does everything, but if the asset owner isn't available, the backup person will help with support roles.

We don't have plans of increasing Zerto usage, as we've always had a relatively static critical VM count of around 300, e.g. we've gone down to 260, we've gone up to 300, but it's always in a range that's close to 300.

My advice to people looking into implementing this product is that if you have less than a 24-hour RPO/RTO and you need it to work in your target location, then there's no other product for it other than Zerto.

My rating for Zerto is a nine out of ten, because nothing is perfect. Nine is the best rating I could give for this solution, but the key takeaway is that it is a single use case product and it does the job.

Right now, we use it just for disaster recovery.

We have always had a centralized data center. Therefore, if we were to lose connectivity or power, then access to county resources would be cut off until that issue is resolved. If there is a hurricane, it would be the same thing. If we lose power, then we would be down until something comes up. With Zerto, I can quickly get us up and running at the disaster recovery site, provided it is still operational.

For most use cases, the failover time is a handful of minutes, if that. A single user can run the system.

Zerto will reduce the number of staff involved in a data recovery situation. As of now, we have been lucky. We have not had to deal with this type of issue. However, it will require less people going forward. So, I can dedicate people to other tasks in a situation like this.

Disaster recovery would initially require four or five people to handle just the server side. This has now been cut down to just one person.

It provides great continuous data protection. The RPOs on things are in seconds.

We have been using it for two years.

We haven't had any issues. It literally just runs. Once you have it set up, you just leave it alone.

As long as I have the resources and licensing, I can keep going from a scalability perspective.

The tech support on my latest issue wasn't so great. I had to figure a lot of stuff out myself. It could be that I had a Level 1 tech who was new or something, but it seemed like the tech was spitballing, which does not help me.

In previous instances, the technical support was great. They were able to get me up and running fairly quickly.

We didn't have a solution like this before that allowed for disaster recovery. Everything was restored from backup, then we had to wait. So, if something went south, then we would need to restore from a backup. I saw the Zerto product was literally one button click, then I can failover to a disaster recovery site and keep going. That was amazing during the initial review of the product. It was just easy.

We started looking at how long it would take to restore from a backup. Rebuilding that infrastructure would take hours, if not days, as opposed to having the ability with Zerto to do a single click, then we are up and running at another site.

It is being used in conjunction with our legacy backup solution.

It was actually fairly easy to set up the solution. Installing it, creating the VPGs, and adding the VMs to it was fairly straightforward.

Working with support on the line, we deployed Zerto in a couple hours.

It is about $1,000 per VM, so it is pricey. However, the cost and time (the manpower cost) that it would take several members of IT to restore a backup and every individual piece of the virtual environment would easily exceed the pricing cost.

If we had to trigger it, downtime would go down to whatever the RPO is at that time. Right now, our RPO average is between four and 10 seconds. This is a big cost saver for us. Anytime certain systems are down within the organization, money is lost.

The only negative part that I have seen so far has been the cost. It is kind of pricey, but you get what you pay for. Zerto is a lot faster than other solutions and you get enhanced performance.

Eventually, we will expand solution use. While there are some competitors in the market, I don't think any of them get to the ease of use and speed that Zerto has. Even Veem has CDP, which is similar, but it is not as fast, user-friendly, or worry-free.

Veeam CDP was still fledgling at the time of our evaluation. It existed, but wasn't that great. It wasn't anywhere near as robust as Zerto. Commvault had something similar as well, but even their solution doesn't do disaster recovery as quickly as Zerto.

It is important that it has both backup and disaster recovery. As I am looking for a backup and recovery solution, I am looking for something that can do everything.

The solution was bought to help with the mitigation of ransomware.

Right now, we are still in a physical data center. We haven't looked at their solution for going to the cloud. That is something which is coming up. Eventually, we will make the switch over. Right now, we are working on a new backup and DR solution. So, that will go hand in hand once we are done with the on-prem.

I would rate Zerto as 10 out of 10 based on the way that the product works.

We use it primarily for backup and recovery of individual servers and databases. We also use it for long-term retention.

It helps us

• achieve our RPOs
• conduct successful DR tests
• provide functionality for some of our key, critical customers.

Fortunately, we haven't gone through an unplanned DR situation, but if we were to go into one Zerto would be the top technology that we would use to recover. We would expect it to function as designed to get everything back to working as normal. Otherwise, obviously, it would be a big problem for our company. Zerto is a critical, core piece of infrastructure for the IT infrastructure team. I estimate it would save us hundreds of thousands of dollars in a DR situation.

In addition, when we need to fail back or move workloads, Zerto decreases the time involved. It's hard to quantify how much time it would save us because we haven't compared it to other DR products. But if we were to use our in-house data protection backup solution or our storage solution, Zerto would save weeks of man-hours when it comes to setup, compared to those other solutions. And it could save minutes in terms of the recovery point objectives.

The instant recovery at DR locations is the most valuable feature. We're required to do periodic DR tests of critical databases, including Oracle and Microsoft SQL. We have recovery point objectives set for specific databases and we need to be able to achieve them. Zerto helps solve that business problem.

Zerto is also pretty simple and straightforward when it comes to ease of use. There were no big surprises.

I would like the ability to monitor the performance of some specific components. Right now we're having an issue with local and remote replications with some of the VPGs. Being able to look at individual VPG performance would be helpful. 

Another thing that would help would be a recommender, or some type of tool that says, "Hey, you're not conforming to best practices." It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on.

Another area for improvement is alerts. We're getting so much noise right now in the 8.5 version. The problem is that we don't know which are the ones we need to act on. We don't know which ones are severe versus those that are informational or notice or debug. They have told us that when we upgrade to version 9 we'll be able to tune some of the alerts. That type of alert tuning, where we can get just the emergency and error alerts, would be helpful, while not necessarily tuning out the informational or notice or debug alerts. If alerts could be channeled to a syslog server where we could filter and see which alerts are the priority that would be an improvement.

We have a network operation center and for us to operationalize this tool with them, we have to be able to deliver each alert along with an action plan for it. That way they can take the appropriate action if Zerto has some type of error. It would help if the alerts didn't just fall on our storage and data protection team. If we could transfer some knowledge and have other level-one teams look at some of the more basic Zerto alerts and try to resolve them, that would help.

I've known about Zerto for several years but I've been actively using it for the last two months.

The stability is pretty good. I haven't seen the software itself break, or the services stop for unknown reasons. 

We did have an issue with a VPG the other day, where it went belly-up, and we had to rethink and do a bunch of baselines. So some type of health monitor that shows both the servers and the VPGs would be helpful.

I haven't worked with the scaling functionality because we only have it in our two major data centers. But I think it would be pretty straightforward and simple to set up scaling.

Currently we're protecting about one petabyte with Zerto. We have some room to grow still with Zerto.

Much like with any technical support—and this is true whether you're talking about IBM, Microsoft, Dell EMC, or any of the big tech players—their level-two guys are definitely good, if you can get one of them. But the level-one guys seem not to be as good. Zerto was acquired by Hewlett Packard Enterprise and it shows with their level-one guys. They're not as vested in the product. All the level-one people who were vested in the product probably left. So a lot of the level-one guys aren't very technical. 

We oftentimes have to work with our technical account manager to get cases moved up to level two. Once they're there, they seem to get some movement, which is good. And, obviously, their level-two support team in Israel is very good.

I was not part of the initial installation, but I've heard that some of the initial pieces are straightforward. Where it gets complex is that I don't know if it was set up according to their best practices.

The pricing follows normal industry standards.

In a previous company, I was involved in the evaluation process that ended with choosing to go with Zerto.

Zerto sits on top of a lot of other technologies. It's like a "Layer 3" for lack of a better term. Some of the other solutions that are "Layer 2" can be more attractive, solutions like Commvault, Rubrik, and Cohesity. They're able to do more native operations at the OS level, like replication. They have more hooks into the operating system to enable you to do that.

However, Zerto's user interface is good. It's simple, it's straightforward, and it gives you the RPOs and RTOs right then and there. It requires some administration from the VPG perspective, but it's able to bridge a lot of gaps.

My advice would be to work with your Zerto technical account manager for the setup and best practices.

Zerto is good when it comes to continuous data protection. We're currently in the middle of some technical support cases with them, cases that I'm watching, regarding some of our larger databases. But so far, there have been no issues with the smaller databases. It's doing its job.

We haven't yet enabled Zerto to do DR in the cloud, but that's something we are pursuing currently. We have had a demo of it but we haven't done a PoC.

Our primary use case is disaster recovery.

We have Zerto deployed on-premises at both our primary and DR locations.

In general, Zerto helps us with our DR plan because it makes things so easy.

Zerto does a very good job of providing continuous data protection. I've been very impressed and would rate it an eight out of ten. Especially when it comes to DR testing, it is very easy to work with and we are able to recover our infrastructure at our DR site within a matter of minutes.

When we have to failback or move workloads, Zerto decreases the time it takes and the number of people involved in the process. I've used other solutions and I haven't seen anything that compares to what it can do. It is difficult to estimate the exact time saving because it depends on the workload.

Realistically, you could have a single admin responsible for the restores, whereas with other solutions, depending on how big your environment is, it would take more people. In our environment, it would take upwards of five people to restore our core infrastructure and by using Zerto, it reduces the number of people by about half.

With respect to DR management, Zerto has reduced the number of people involved in the process. I wasn't at the company when they used the previous product, so I'm not sure by exactly how much.

The most valuable feature is real-time replication, where we have the ability to recover things in near real-time.

It's very helpful for DR testing because we can recover VMs in an isolated bubble and prove our DR methodology.

Zerto is very easy to use, which is one of its big selling points. It takes just a few clicks to restore a VM, which means that it's easy to train somebody to help in a DR situation.

We have had some issues with trying to get certain parts of the backup or restore functionality to work. However, I cannot recall the specific details.

I have been using Zerto since I started with the company two years ago. In total, the company has been using it for approximately four years.

The stability has been very good. I can't think of a time that we've really had any issues that we didn't cause or something maybe with an update. We're running it 24/7 and I can't think of a time that we've had any major issues with it.

From my perspective, Zerto's scalability is very good. We have 60 VPGs and 122 virtual machines that we're using Zerto to replicate to our disaster recovery site. This will grow with any new infrastructure that we build. Any new servers, depending on their RTO or how soon we need to recover them, would be put into Zerto. Potentially, we will add some, although I'm not aware of any major growth at this time.

Our operations department monitors the dashboard just to confirm that our RTO and the VPG health look good. There are perhaps five people in that team, who are watching the dashboard.

In my team, there are three of us that use it, although we don't look at it daily. It would only be if we get reports of an issue or we need to adjust a setting or something like that.

Overall, on a day-to-day basis, there are probably about five people that use it.

I have not personally dealt with the technical support but I know about the experience that my coworker has had. They are typically very helpful and provide good responses compared to other companies in the industry.

Zerto was recently acquired by HP and there is some concern in our organization about what might happen to the technical support, seeing as they were bought out by a bigger company. We're hoping that it doesn't negatively impact the support that we receive.

I have used Veeam in the past and it's similar to Zerto in certain aspects. They both have their pros and cons, but I would say from what I've seen, I like Zerto. It just seems to be a little bit more user-friendly in the UI. Functionality-wise, they're similar. I think Veeam would be one of their main competitors.

I have also used the older product by VMware called Site Replication Manager. It really doesn't compare to Zerto.

I have been involved in some of the Zerto setups and from what I have seen, they go very well. It seems that it is pretty easy to perform the initial setup.

It takes about an hour per site, or per server to upgrade it. 

We deploy and upgrade the solution in-house.

It's usually two people that are responsible for maintenance but it could be four people on the team.

I believe that we have seen a return on our investment. The return comes from time saved in manpower, for example. From what I've seen, it's worth the cost.

I've also heard comments from my coworkers to say that it's an expensive product but it definitely makes you feel more comfortable in a DR situation.

I have not been directly involved in the pricing and licensing. My understanding is that it's expensive but worth the price.

We don't use Zerto for long-term data retention and I'm not aware that there are any plans to do so. We use Zerto in tandem with our backup solution, just to be safe. That said, we have used Zerto for recovery in scenarios where we couldn't find the particular data that we were looking for in our other backup solution. 

We have not experienced any ransomware incidents or other situations where we needed disaster recovery. However, Zerto would definitely save us time for that. Depending on the situation, it could save the number of people involved as well.

Although we have not had to use it in an actual event, it helps us in terms of regulatory and audit compliance. If we had a real event, we would all feel more comfortable that we'd be able to restore or be in a better position to have our infrastructure restored in a small amount of time.

We have not yet looked into using Zerto for DR in the cloud but in the future, we're going to look at the option of doing so.

My advice for anybody who is considering Zerto is to do a proof of concept or a trial. I'm not sure what the vendor has available in this regard but I would advise trying it out with a small number of virtual machines.

I would rate this solution a nine out of ten.
