HPE Zerto Software Reviews

We use Zerto for disaster recovery as a service and site-to-site migrations. 

Zerto enables us to do sandboxing failovers. You can run tests on a production environment in a sandbox and spin up a copy of your actual production environment in a few hours. When you're done with it, you can click a couple of buttons, and it's all blown away. You don't need to worry about reverting changes or interfering with your on-prem production environments.

The most valuable feature is the overview Zerto gives you, providing quick insights into where your VMs are and whether they're replicating. It's an easy interface to work with. Configuring Zerto to failover in Azure is pretty simple. The biggest challenge is moving from on-prem to the cloud, but that's not an issue with Zerto. The problem is the difference in hypervisors.

I would like to see some improvements with APIs going into the cloud so that they can more natively orchestrate the migration point-to-point without special hands-on configuration. Azure does some of that natively by having an agent on the VM, but Zerto could improve on its APIs into Azure or Google so that spinning up works more natively in that environment. It would make things smoother. 

I've been using Zerto for about a year now.

I haven't faced any stability issues. The only problems I've had have been self-inflicted, so it's pretty good.

Zerto's scalability seems pretty robust. I've had a few larger VMs that have been a little troublesome in terms of the RTO, but they are also outside of best practices. There should be no issues with scalability if you're working within the defined parameters of what's acceptable.

I rate Zerto support nine out of 10. I've used their support pretty extensively. I would say the majority of the experiences have been overwhelmingly positive. Their response times and issue resolutions are satisfactory.  

One thing I would change about Zerto support is the fact that you sometimes can't find the answer you need online. Sometimes, Zerto reaches out with an answer to that particular issue, and it's in a document that the customers can't access without going through support. It doesn't feel like that information should be limited to internal use. I should be able to find that online without going through a support channel. 

I've also used Azure's native Azure Site Recovery solution, and there are definitely some benefits to using Zerto, such as the fact that it works at a hypervisor host level over individual VMs with agents. The performance is probably a little better in most cases. 

Zerto is easier to use than ASR overall, but the setup is a little bit more involved. After the installation, the daily use is pretty simple compared to Azure. With Azure's native solution, there's a lot more that you must do repeatedly throughout the lifecycle of any virtual machine or system that you're trying to protect. Zerto is much simpler in that regard.

The on-prem deployment is super easy and works well. Migrating from on-prem to the cloud involves a lot more steps and things you have to configure so that it can communicate into the cloud and build everything that it needs to. That takes more time. It probably requires twice as much time to deploy on the cloud. 

We see the biggest ROI from Zerto's real-time test environment. If we want to do a proof of concept on a hundred servers, we can spin them up within a few hours and have them ready to start testing stuff with real data to see how that might look if we were to deploy that into production. It's an excellent, accurate test environment that we don't need to maintain.

Zerto's pricing is competitive, given the benefits and ease of setting it up. It may seem more expensive upfront, but you're going to save that over the long term by spending less engineering time configuring, reconfiguring, etc.

I rate Zerto nine out of ten.

We use Zerto to replicate all of our production solutions. We replicate to cloud storage.

Zerto works really well. It's simple to set up and works well. Moreover, disaster recovery to the cloud for our organization is very important. We actually had to use it three years ago, and it worked out well for us.

It replicates a lot quicker than what we were using previously. We did see a reduction in the time it takes to replicate. We were using SAN replication, and Zerto works in about a quarter of the time.

We use Zerto to protect our VM environment. 

Zerto works reliably and that is simple to set up and manage.

Moreover, Zerto's Near Synchronous Replication is fast. It lets you recover to a very short point in time, so you don't lose anything. It's really important because we don't want to lose any of our data. We want to be able to recover as much as we can. So this feature helps us do that.

Overall recovery time objective (RTO) with Zerto is really good. It's within seconds for us.

When we migrated to a new virtual infrastructure, we had to set up Zerto all over again which took a long time.

It would be nice if Zerto had some sort of migration tool where you could migrate all of your virtual machines to a new infrastructure without having to set up Zerto all over again.

I've been using Zerto for about four and a half years.

It works really well. We rarely have any sort of issue with it. You just set it up and it does its thing.

We are a smaller environment, but it seems like it would work well for much larger organizations too.

We protect 36 virtual machines right now.

The customer service and support are really good. They reply quickly and they usually resolve the issue in a very short time frame.

Positive

We looked at Veeam, Veritas, and some other storage-level replication solutions. We chose Zerto because it was just simple to set up and had good reviews. It works well and is pretty simple to use.

The initial setup is pretty simple. We had it set up and replicating in about three hours. It's really quick to set up and works pretty simply.

We definitely have seen a return on investment from Zerto. We were able to recover from an incident that would have been a lot more serious without Zerto.

Without Zerto, our organization would have lost several million dollars in financial damages from data loss.

The solution is a bit pricey for sure. But the licensing is simple to understand, which is good.

Overall, I would rate the solution a nine out of ten. 

Our primary use case is for disaster recovery. We replicate up to Azure, and that's essentially disaster recovery as a service.

Overall, the effects of RPO have been great. They are never more than a minute or two, even throughout the production day.

If we can replicate from our native VMware environment up to native Azure, it converts the machines for us. We don't have to maintain another VMware environment somewhere. It's really given us the ability to eliminate the entire data center.

Moreover, there are cost savings tied to this. We don't pay for the rack space, power, or hardware; all of that is gone. Because the machines aren't active, all we're paying for is storage in Azure. So it has saved us quite a bit of money.

Zerto's near-synchronous certification has positively impacted our operations. Any recovery point that's too far in the past, we'll lose transactions when we fail over. We really don't want to do that. Real-time replication gives us a much better sense of security for the enterprise. It simplifies things for us and reduces costs.  It makes management feel really good, too.

Using DR in a cloud environment has been a positive experience. We're saving money. We don't have to maintain the hardware. We don't have the rack space at the other data center. It just simplifies things for us and reduces costs. It's been a positive experience overall. It's pretty easy to use. Once it's up and running, it stays running. We have had a few times when we called support and the support has been very, very good.

Maybe the reporting for the failover test could be a little better.

I have been using Zerto since 2020, so it's been three years.

It's very good. It's very stable. It doesn't require a lot of intervention. 

We haven't had any problems with scalability. We have 75 machines protected by Zerto and it does a fine job.  

Support has been very good.

Positive

We used to use Site Recovery Manager when we had two data centers, and it was VMware to VMware. We were using EMC storage. Zerto is a lot easier to use than Site Recovery Manager. It requires less care and feeding. 

Site Recovery Manager occasionally would lose virtual machines, and it was kind of a pain, but Zerto just kept running. So overall, we're really happy with the switch to Zerto.

The initial setup was easy.

Since we don't have to maintain all of the hardware and the second data center, one person can manage the entire Azure environment by themselves. As a result,  Zerto has helped us reduce staff. 

We did an assisted setup with Zerto tech on the line, and It was really painless. It was simple and straightforward. The initial process including getting the servers and everything set up, was pretty short. The process included getting the VMs all added to the recovery groups and things like that. 

The whole process from start to finish took less than a week.

It has proven to be a cost-effective solution for us. 

It could always be less money. 

Overall, I would rate the solution a ten out of ten. It requires little care and feeding. Not a lot goes wrong with it. It just works.

We are using it for disaster recovery. We have recovery point objectives (RPOs) for our ERP systems, financial systems, and real estate systems.

We only use it for on-prem disaster recovery. We are not using it for the cloud.

When we replicated our data, I turned up the machine, and it was up in seconds. It blew my mind. I could not believe it. We made a change to the database and tried to bring it back, but it did not work. I was floored by how quickly the system came up, but unfortunately, I need to get the rest of it working. We have not spent a tremendous amount of time on it. We are stuck, and we have not been able to play around with the full features of the system.

Unfortunately, we have not been able to get it to be fully functional. We were able to replicate and turn up a VM, but we were not able to bring the VM back because my team was spread thin. However, we worked with tech support and got the VM back.

I have been using Zerto for one year. 

We have not been running it long enough to see its stability.

I have a small group of virtual machines. If I buy more licenses, I am sure it would work just as well. We have fifteen VMs for our core production, financial systems, and real estate systems.

I did not work directly with them. My systems engineer worked with them, and he was not tremendously impressed. He had called their support, and the impression that I got from the engineer was that they had never seen that before, and they did not know.

We purchased VMware Site Recovery Manager, but we made a lot of hardware changes. I never got it working, and I stopped paying for the licensing. I cannot compare Zerto with VMware Site Recovery Manager because I never got VMware Site Recovery Manager working, so I did not use it.

We went for Zerto because we wanted something from a reputable company that I know works and that I can get up and running with the recovery point objectives that they advertise. I was impressed when I brought it up. It met my expectations.

We paid Zerto to help us get it installed, and we paid for the quick start. However, I did not read the contract closely. The person was very helpful, but unfortunately, we did not understand that we had a limited period of time. When we went to ask for support, they said sorry and asked us to buy more hours. That was our fault. It was not explained properly, but I cannot blame Zerto because we just did not read it all. It was a line item on the contract. It was not until they said that I only had six months that I pulled up the documentation, and it was a line item off to the side that said that we had six months total for the start-up, so we did not get the environment fully set up.

When we worked with the quick start engineer, he made some recommendations about setting up a test environment. He made some recommendations here or there, but it failed to launch. When we were working with the engineer, we had some of the same problems that we had after deployment. For example, in some cases, some test machines would never boot up. We then had to redo it and do some other VM. Even at the time when we were working with the engineer, we could not bring it back, and we never resolved the issue because the time expired. Some of that is on us. We get pulled in different directions, and I did not understand the limitation. 

I have not yet seen an ROI. I will see it when I resolve my issues, and I can bring my entire environment over and get it up and running.

I do not have anything to compare it to. It is expensive, but I am not going to squabble about the price when I bring the system up in a disaster. It is what it is.

We did not evaluate other solutions.

At this time, I would rate Zerto a five out of ten. I was extremely impressed at how I was able to bring that system up, but because I have not been able to bring it back, I am in the middle. Once I can bring it back, I will be super impressed and rate it a ten, but right now, I am right in the middle. It worked great for a minute.

Currently, our use case is to create a replicated system. We have no access to the internal VMs. We can manage the VMs up to a point, but we cannot get inside to do any kind of corrective actions to the servers themselves. We had no backup solution in place, so we needed to get something there. That is what we are using it for. It is replicating out to Azure. This way we have some place in case the ones on-site get compromised or have issues.

We are moving to a new data center. There are several VMs that we have to move over there that have RDM disks or SQL clusters. Those are the hardest things to move at this point in time, but now that I have the setup and it is ready to go, all we have to do is just flip the switch and get everything over where they are supposed to be. It is going to be a lifesaver for me. It will save me a whole lot of time in putting things back together.

Its initial setup can be better. It looks easy, but if you do not have things in the right place, it is not as easy as it looks. Some of the instructions were not clear. They were a little bit confusing. For example, while setting up SSH initially, it was a little bit unclear if I needed to use a regular credential or some other credential. This was one of the things that was a little fuzzy, and we had to get somebody else involved to help us out.

I have been using Zerto for about a year.

It seems to be pretty stable provided our network stays up and the firewalls do not go down.

I have not had to scale it yet, but we are planning to replicate an environment of roughly a thousand machines.

I would rate their support an eight out of ten because it took a while for the communications back and forth to get it set up. We could not always get together at the same time. We would also run into an issue, and we had to go to development or somebody else to figure out what was going on with it. We would then wait for that response. There were a lot of issues that we had that required a lot of back and forth.

Positive

We did have SRM in place for a little while for about 75 machines. Most of the machines that were being replicated with SRM went away when we had a dissolution with another part of our facilities, so we pulled that out and stopped using it. We then went to Zerto about that same time. 

We are not using it for a full DR. We have another solution in place for doing the DR work. Zerto, at this point, is primarily for replication. 

We are also not using Zerto to help protect VMs in our environment. We are using another solution for that.

It was a little rough, but it was not terrible. When we were setting this up, I was working with several machines that were 30 or 40 terabytes in size. Moving that data out to that other location was a long, slow, and ongoing process. There were several times when we had to reach out to their support to try and figure out what was going on. We had to make some adjustments to how they were configured, but that was the biggest challenge we had with that the whole time.

It is slow initially, but once you get it all up there, it is not so bad. It took days to get that data moved. Once it got up or synced, it was down to seven or eight minutes, but it took days to get everything up there to begin with. It took about a week from start to finish to have it fully deployed.

We worked with a Zerto rep. They said that this is what we need, and we got everything in place, but then as we were trying to deploy it, we had issues. We had to pull in support to help us straighten out what we were having problems with. They have been pretty good. Fortunately, I have not had to call them much. Once we got it set up, it was fairly easy to figure out, but doing that initial configuration was a little difficult.

We have not yet seen an ROI. We are going to be moving to a new environment and a new data center. I am sure I would see a big return on investment at that point.

I did not evaluate other options, but there were some higher-up managers who were involved in those conversations. They had neglected to involve the guy who was going to manage it. I heard that they evaluated Veeam, an IBM solution, and Zerto.

I would rate Zerto an eight out of ten only because I have not used it a lot. When we move to the new environment, I am sure I will use it a lot.

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 had a specific use case for one of our clients that had a regulatory requirement for backups to be further than what we were already able to give with our current backup structure. We are actually a global company and our global headquarters are in Northern Ireland. We're located in Pennsylvania. We're the North American headquarters. We implemented Zerto, and we replicate on our Northern Ireland site. That got us more business with our clients.

We needed to meet the requirements of the client, and, previous to this solution, we would not have been able to meet the distance. That's why we implemented it.

The journaling is the most valuable aspect of the solution. The near synchronous authentication is great. It's critical for our organization.

We haven't had to use Zerto for blocking threats, however, we like that we have it as an option.

We do not do disaster recovery in the cloud or the AWS platform. It can do it. We just don't opt to use it that way.

We've used the solution to protect virtual machines.

It's had a positive effect on our RPOs. Our RPOs are eight seconds. It blows past RPOs out of the water. It's great.

The speed of recovery is excellent. We've only had to test it and never used it in production. That said, it works better than anything we've used previously. 

It's easy to migrate data. 

Its ability to keep users collaborating during a data migration is good. It goes very quickly, so it's not a disruption.

The impact on our RTOs is great. It far exceeds what we've needed it to do.

It will save us time in a data recovery situation.

It's helped us reduce our DR testing. It has gone from hours to minutes under Zerto.

It enables us to make better use of our staff. We have reduced the number of staff involved in overall DR management. 

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

I have used the solution for close to six years.

The stability is great. We haven't had any issues with it. 

The scalability is very good. It can scale out to quite a lot of VMs.

I've contacted technical support once or twice. It was for integration and customization and they've been great.

Positive

I was involved in the initial setup, which was very straightforward. It took about a day to set up. Two people were involved in the deployment.

The only maintenance is the annual upgrade. It's pretty much set and forget.

We handled the setup with the help of Zerto.

It's hard to quantify the ROI. 

The pricing is pretty fair. It's competitive.

We did look into VMware. It didn't meet our requirements.

The solution has not replaced any of our legacy backup systems.

It hasn't helped us to reduce downtime, as we haven't had any yet.

I'd rate the solution nine out of ten.

The only issue is that someone would move the VMs involved around. If you have a global team, make sure they understand the strategy and everyone is on the same page so that issues like that don't arise. We had silos on our side and once we dealt with that, we were fine.

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.

I am the global lead for infrastructure for the VMware and Windows Server environments. We are mainly using Zerto for disaster recovery. We have a prime site in Missouri, and we have plants in Taiwan, Malaysia, Japan, Italy, and Korea. We have 400 to 500 users in the environment. 

We have installed Zerto software on the DR site and the production site. We will be using Zerto for the production site for all the centrally used applications, such as SAP, file servers, and Exchange. Because this is a central site, a lot of other sites come to this site for various things. 

We also have Zerto on the DR site. In manufacturing, there are 60 or 70 tools, and each tool costs around $500,000. When the site goes down, you cannot transfer these tools very easily. It takes time. These are big tools, and it takes time for them to go somewhere else. You have to do a test again and go through the qualifications procedure, which takes time. As the IT department, we are interested in getting the applications that are used by all the sites centrally located, and if anything happens to the primary site, we want all the applications to be already there on the disaster recovery site. We just bring them up, and we are good to go.

Zerto will help to protect VMs in our environment. We have tried that in the test environment. That would be another reason for using Zerto.

We have used it for VMs. We know that it is a very good product. So far, we have only synced SAP and tested a few things. For SAP, there were two guys doing that, and they like Zerto very well. They have the test databases up there. It was smooth, and they liked it. The part that we still need to test is the Windows VMs where we can spin up a domain controller, change the IP, etc.

We can move data that is needed to keep our users collaborating with one another using Zerto because we are doing a continuous sync of the site. Once it is synced, we do not have to worry because everything happens in the background.

The replication feature where it constantly replicates and sees that data is always in sync is valuable. 

The ease of moving all the VMs is valuable. All we have to do is change the IP address and the VMs are all up and running there. There is a passive sync with all the VMs. That is what we like about Zerto. VMware has its own tool, but you need to do a lot of scripting. In manufacturing, we have a one-man team, so we do not have time for all the specialized work. We needed an application that is more GUI-based so that we can pinpoint and easily move VMs. We can bring up all the VMs and make sure the data is in sync, and we are up and running, so the ease of implementation is what attracted us to Zerto.

Zerto is very easy to use. It is very professional. We had no issues at all. Even for bringing up a new ESX host, they have a standard procedure. It is very easy. With a few clicks, you can do the ESX installation. 

There should be an automatic installation in a cluster. When I add a virtual client or ESX source to the cluster, it should automatically install that. There should be automatic installation. Currently, I have to do that manually.

They can give us a few training classes.

We installed Zerto just three months back. We have not yet started using it properly.  

Zerto is a very stable product. We have no issues. So far, it is working as planned. It is very stable. We will soon be working on it full-fledged. 

It is very scalable. We buy new licenses, and we just add another ESX or VM. We manually install it, and then we are good to go. It is pretty easy.

We have not contacted support yet. So far, so good. Everything is working as planned.

I tried VMware replication, but it was too hectic with all the scripts, so I gave it up. 

We implemented it recently. There was the ease of implementation. It was easy and straightforward. 

In manufacturing, we have to make sure that everything is on-prem. The data has to be on-prem because all the tools write immediately to the servers. There are two types of manufacturing. For the type of manufacturing where your tools are constantly writing, cloud applications are not good. For example, when we scan wafers, there is a set of data, and when we go through another tool, there is another set of data. This has to be instantaneous. There is nothing called a cache or buffer on those tools. It has to be instantaneous. We cannot say that the cloud is down, and we lost the data. We cannot stop the tool because this is a manufacturing facility with 24-hour operations on 365 days. We cannot have any downtime where the full site has gone down because this site is used for central applications.

I am the one who implemented it. Overall, there were just two people involved from our side. There was me and one more person. Because it was a new product, we also had a representative from Zerto as a standby. He would just watch our screen while we were implementing it. When we got stuck somewhere, he would help us. Because this was a DR site and it was a little far off, we wanted to make sure that everything went smoothly.

In terms of maintenance, so far, it did not require any maintenance from our side.

Having a solution like this is similar to having insurance. When you have a car accident, that is when you know the value of your insurance. Similarly, you cannot put a definite value on a solution like this till something happens, but there is peace of mind in knowing that the software is there, the VMs are there, and we can test it anytime. That is the true value.

It is economical as compared to other brands. 

We are an HPE shop. Zerto was procured by HPE, and we were looking for a DR solution. We went for Zerto because of its simplicity and ease of installation. We did an on-site proof of concept of Zerto for a year. We liked it and purchased it.

The only other product that we looked at was the VMware one because of the orchestrator. We did not look at any other products. I know that Veeam also has the same features that Zerto has. We had some discussions, but we never looked into it. Once we had a product that was easy to install, we did not feel the need to compare. It was doing what we wanted it to do.

Another factor for going for Zerto was that its price was economical. My boss, who is the CTO, liked its licensing scheme. It was much more economical as compared to VMware, and that is why we went ahead with Zerto.

Before implementing this solution, in terms of preparation for disaster recovery, you have to identify the business applications that are critical to your environment. You have to scope that out and make sure you have your VMs accounted for because licensing depends on the number of VMs. With a product like Zerto, you have to know the number of VMs and the size of data you are going to sync. These are the two factors that you have to look into for disaster recovery. 

Zerto is way better than other products. Installation is done with the click of a button. Everything happens in the background. You do not have to worry about it. As a product, we have not had any issues so far. However, we have not yet done a full-fledged disaster recovery. We have done minor testing, and we want to do major testing. As of now, I am very happy with the product. It does not need any further modifications. It is simple. It is nice. It is easy to execute, so I would keep it that way.

We have not yet used Zerto for immutable data copies. I have been playing around to migrate a VM and see how it works. So far, we have only used it to sync up the SAP side. Our SAP stuff is already synced up, and we have done some testing of it, but we have not done any disaster recovery.  

I have not had a chance to assess Zerto for blocking unknown threats and attacks. We are mainly interested in using it for disaster recovery.

Overall, I would rate Zerto a ten out of ten.
