The solution was primarily used for disaster recovery for clients. If there was a major issue in the data center, it allowed the client to move to the second data center. It was also used for migration to virtual machines.
HPE Zerto In-Cloud Software for AWS
Hewlett Packard EnterpriseExternal reviews
External reviews are not included in the AWS star rating for the product.
User-friendly, easy to set up, and offers good speed to recovery times
What is our primary use case?
How has it helped my organization?
My customer recently (a few years ago), had a major issue in one of the data centers. It was a virus attack that destroyed the servers and virtual machines. We could not recover those servers or virtual machines. After that, we decided to remove the corrupted data center and get everything recovered using Zerto. We were able to do that with the agreed-upon RTO and RPO for the customer.
What is most valuable?
The replication between data centers is great. It allowed us to ensure all data was replicated from one side to another.
The near-synchronous replication is great to have. It works better than other solutions.
It's very user-friendly and straightforward. There are no bugs in the software.
The disaster recovery features are the best I've found.
This product allows us to do disaster recovery in the cloud rather than the physical data centers. We have multiple customers who are on a hybrid cloud. Some are on a private cloud and some are on a public cloud and Zerto allows us to provide the functionality whereby we can cover both as well as across physical data centers. We use Zerto for AWS, Azure, and GCP.
It was nice to use with AWS. Everything was in place on AWS and the functionality is well documented. We've done a POC on it. We have not yet had a chance to do a real disaster recovery just yet.
Zerto has helped us protect VMs in the customer environment. The overall effect on the RPOs is good. We can do it at a maximum within 15 minutes, however, often we can do it within five minutes, or even one minute.
The speed of recovery is very quick compared to other tools.
It's easy to migrate data with Zerto. It's simple. Even non-technical users can see what information is needed in order to enable the replication from one site to another.
Users can still collaborate during the migration process in Azure. It depends on how much data you are including from your data center. The bandwidth connectivity between two data centers is very high.
The RTO is pretty good. We typically give our customers a heads up it will be eight hours, however, it's often less.
It's helped us reduce downtime. For example, when I was using another solution, we wanted to restore a VM. It took more than eight hours to restore ten virtual machines. In contrast, Zerto only takes 45 minutes.
We had a corruption at one point on 20 to 25 VMs, that were critical from the customer's point of view. They had already spent so much time trying to troubleshoot. We decided to use Zerto to restore the machines and give them the latest backup. We were able to give them everything in less than one minute.
For the customer to recover using a different solution, it would take much longer. Zerto takes far less time. For example, compared to VMware SRM, it takes almost double the time compared to Zerto.
We've been able to reduce DR testing. When we used to give RPO and RTO time to our customers, two hours for RPO and eight hours for RTO, once we started using Zerto, we reduced RPO to 15 minutes.
It's reduced the staff time involved in a data recovery situation. When we initially set up Zerto, it immediately starts replicating and does incremental replication as well. Therefore, at any given point in time, the latest data is already available on the recovery side. We just have to trigger it and everything will be restored as per our configuration. We likely save three to four hours of work during the disaster recovery period. And, in the disaster recovery phase, every minute is crucial.
It's also reduced staff involvement. It's not complex and very straightforward. Since tasks are reduced, we do not need so much staff.
What needs improvement?
Previously, it was not compatible with the public clouds. However, now that it is, it's helped a lot. One of the most challenging aspects in migrating items from private to public.
We'd like to be able to migrate data without its operating system or any other functionality and without having to go through a virtual machine or server.
For how long have I used the solution?
I've used the solution since 2015. I stopped using it around 2022.
What do I think about the stability of the solution?
The solution is absolutely stable. We have customers that have used it since 2016 without any concerns.
What do I think about the scalability of the solution?
The product can scale.
How are customer service and support?
We haven't had to engage with technical support.
Which solution did I use previously and why did I switch?
I'm familiar with VMware SRM.
Not a lot of people in the market are aware of Zerto. They need to market it better.
However, Zerto is pretty simple and straightforward, compared to other options on the market.
Replacing the legacy solution has helped customers remove compatibility issues and reduce costs.
How was the initial setup?
The deployment of the product is straightforward. We have, for example, more than 100 VMware ESX-site servers and there are two agents in terms of virtual machines that get deployed on all of them.
To deploy the solution, it only takes 30 minutes. You only need one or two resources to manage the implementation. The maintenance is minimal. Once it's set up, it's fine.
What was our ROI?
Our customers have witnessed an ROI.
What's my experience with pricing, setup cost, and licensing?
The product is cost-competitive and less than other options. I do not have too much data on the exact costs, however. However, we are definitely saving costs when we compare Zerto to VMware.
What other advice do I have?
My understanding is we have a partnership with Zerto. It provided free training to our employees and we have done multiple certifications.
We did not use it for immutable data copies.
We don't use it for blocking unknown threats and attacks. We don't use it for security purposes. We have other security protection services for our customers, including firewalls and antivirus. We use Zerto only for disaster recovery.
I'd advise potential users to pay attention during the initial setup and watch what you are replicating from one side to another. After the setup, you will not have to put a lot of time in - as long as you pay attention during the initial phase.
I'd rate the solution nine out of ten.
Easy to set up and use, offers reliable performance
What is our primary use case?
We use Zerto to replicate all of our production solutions. We replicate to cloud storage.
How has it helped my organization?
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.
What is most valuable?
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.
What needs improvement?
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.
For how long have I used the solution?
I've been using Zerto for about four and a half years.
What do I think about the stability of the solution?
It works really well. We rarely have any sort of issue with it. You just set it up and it does its thing.
What do I think about the scalability of the solution?
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.
How are customer service and support?
The customer service and support are really good. They reply quickly and they usually resolve the issue in a very short time frame.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
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.
How was the initial setup?
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.
What was our ROI?
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.
What's my experience with pricing, setup cost, and licensing?
The solution is a bit pricey for sure. But the licensing is simple to understand, which is good.
Which other solutions did I evaluate?
What other advice do I have?
Overall, I would rate the solution a nine out of ten.
Easy to use, scalable, and fast migration and recovery
What is our primary use case?
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.
How has it helped my organization?
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.
What is most valuable?
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.
What needs improvement?
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.
What do I think about the stability of the solution?
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.
What do I think about the scalability of the solution?
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.
How are customer service and support?
I have not yet called their support. I did not have to call them.
Which solution did I use previously and why did I switch?
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.
How was the initial setup?
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.
What was our ROI?
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.
What's my experience with pricing, setup cost, and licensing?
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.
Which other solutions did I evaluate?
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.
What other advice do I have?
Overall, I would rate Zerto an eight out of ten because we do not yet know everything.
Simple UI, quick disaster recovery, and responsive support
What is our primary use case?
We use it for disaster recovery. We do disaster recovery in the cloud as well. We also do routine testing of the disaster recovery functionalities.
How has it helped my organization?
We do disaster recovery in the cloud. Having DR in the cloud is absolutely fundamental. Backups are great, and disaster recovery is quick. If something is down, with the click of a button, we would be able to spin up multiple assets. Zerto allows us to do that.
We primarily have Azure, but we also have some integration with AWS. We found it pretty seamless. There are a couple of pain points every now and then with setting up policies and getting things to work as expected, but their support is very helpful for any of the cases that we run into. Whether it is running against RTO or having issues with certain VMs and certain workloads, we have been able to work through these issues and get it functioning as expected.
Zerto has been very helpful for RPOs. It definitely keeps us at our target recovery point. It is definitely the most important toolset for us to meet the RPOs.
Zerto definitely helps our engineers sleep better at night because we know that we can meet our RPO. We have an immediate button if we have to do a restore. Sometimes, we look in Zerto first rather than having to dig out of backup. That is probably Zerto's highest value-add.
It does near-synchronous replication. CDP has definitely come a long way. They were the first ones to do it, and they have definitely done it the best in my opinion. Other solutions that are out there are trying to emulate it, but in our stack, Zerto will always be the one on which we rely the most for continuous replication. For production workloads, this continuous replication is absolutely critical. We have a lot of SQL data and things that are constantly changing. It is sometimes a little bit of a struggle for Zerto to keep up with that much change rate, but with the tweaks that we have made, it has definitely been more possible. It is definitely something that is important to us, and for production apps, it is absolutely key.
What is most valuable?
There are a lot of features. The UI is straightforward. It makes it very simple to group our resources and understand that our production workloads are covered because we can set them up as granular or as non-granular as we want. If we want to select an entire cluster, we can do that, or we can group it by application, which is the best practice and what we do as an organization.
What needs improvement?
The biggest pain points we have experienced are related to some of the SQL-intensive workloads just because the VPGs struggle a little bit to keep up. That might be because we are pushing too many transactions. That might be on us, but that would be my main suggestion. There might be a way to tweak the settings. There is an option to exclude scratch disks or temp disks in SQL, and that helps, but we still struggle a little bit with the databases with high transaction volume for the VPGs to keep up. We have done a little bit of work with the monitoring features that they have in the portal to identify whether ZVM or something else is overloaded and then allocate more resources to it, but there can be a little bit more transparency. If there is something they can do along those lines, that would be awesome.
Deployment is an area that can be improved a little bit. Sometimes deploying new ZVMs and things can be a little confusing. Also, with the supportability matrix, there is a little bit of a gray area sometimes as to which version is supported. There is some opportunity there to improve transparency around versioning and what to use moving forward for all workloads.
For how long have I used the solution?
I have been using Zerto for about five years between multiple organizations.
What do I think about the stability of the solution?
It is very stable. We have no issues. We do not have to worry that Zerto will go down. We shifted most of our on-prem into Azure, and it works flawlessly.
What do I think about the scalability of the solution?
It is definitely scalable. It just works. We can add more VMs. We can add more ZVMs to scale with the business needs.
We are using it mostly for the production workloads. We have a couple thousand VMs.
How are customer service and support?
I would rate them a nine out of ten. It is hard to get a ten out of ten. There is always more that you can do with support, but they are always very responsive. They helped us through multiple issues with different VPG replications. We have had some issues there, and they were always very good at guidance. They always have a solution and a lot of good documentation as well to reference before opening a case. That is helpful.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I have only used Zerto in the past. That is the one I am the most familiar with and comfortable with. I can compare it to other backup tool sets that I have used in the past, but I know Zerto is not exactly a backup solution.
Its UI is very simple. I always find what I am looking for relatively easily. As they have evolved the web portal, it has only gotten better. The UI is definitely on point today.
What was our ROI?
I believe we have seen an ROI, but I do not know the exact number. We are definitely seeing a good return from what we have put into the Zerto product. Our business users said that it is very important to them to have disaster recovery and for us to be able to perform quarterly tests with all these different application stacks. We can show them what it is like to bring up a bubble environment and do full testing.
Which other solutions did I evaluate?
It was a little before I joined the company, so I cannot comment on the solutions they evaluated.
What other advice do I have?
I would rate Zerto a nine out of ten. There is always room for improvement. There could be a little bit more transparency around releases and what version to use. They have done some rebranding in the past such as ZRA and ZVM. There is some confusion there sometimes related to some of the internal terminology when you do not work on it every day, but overall, we are very happy with the product. It does what it is intended to do, and as a customer, that is all you can ask for.
We could replicate and turn up a VM in seconds, but it is expensive
What is our primary use case?
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.
What is most valuable?
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.
What needs improvement?
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.
For how long have I used the solution?
I have been using Zerto for one year.
What do I think about the stability of the solution?
We have not been running it long enough to see its stability.
What do I think about the scalability of the solution?
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.
How are customer service and support?
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.
Which solution did I use previously and why did I switch?
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.
How was the initial setup?
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.
What was our ROI?
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.
What's my experience with pricing, setup cost, and licensing?
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.
Which other solutions did I evaluate?
We did not evaluate other solutions.
What other advice do I have?
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.
Easy to use, good documentation, and helpful for minimal downtime
What is our primary use case?
We use it for failing over our production servers in the event of an emergency so that we have minimal downtime to continue business operations.
We only use it for failover to on-prem. We do not use it for the cloud.
How has it helped my organization?
Zerto was one of the first failover solutions that we implemented in the organization, so the benefits are pretty drastic. It is hard to compare it to any other solution out there because we do not have anything to baseline it on, but it certainly increases the confidence of our end users. We are able to react in the event there is an issue. The fact that we are not waiting for hours to restore operations is something that we find valuable.
We protect VMs in our environment with Zerto. We are very happy with the RPO results.
What is most valuable?
Its ease of use is most valuable. The online documentation is very clear and helpful. We are able to solve a lot of problems on our own without having to contact support.
What needs improvement?
We learned that we got a new account representative supporting our account. I found this out today. Apparently, this is something that they kicked off at the beginning of this year, but there has been a failure in communication in letting us know who is the proper channel for us to reach out to if we need assistance.
While going from the major version 9 to 10, they introduced a new requirement for ECE Licensing, which is not something that we knew about at the time of our last renewal. We purchased it for a couple of years, and as far as we knew, we were in support. It was only when we were in the middle of the upgrade and had set up the entire environment and tried to put it up, it asked for a license key that we did not have. We were told by the support team to reach out to our account manager. She has been a bit slow to respond. It just seemed like lip service. The timing kind of worked out because there was a conference as early as that. They have been trying to fix it and communicating about it. I am hopeful it will be resolved, but I just cannot say for sure how soon or how fast they can remediate it.
For how long have I used the solution?
I have been using Zerto for about two years.
What do I think about the stability of the solution?
It is stable.
What do I think about the scalability of the solution?
We have not had any issues increasing the number of VMs being protected as long as we have licenses. We have over 100 VMs.
How are customer service and support?
They are responsive, but when things need to be escalated, it is very unclear who is going to be the person to ensure that things are resolved. I would rate them a six out of ten.
How would you rate customer service and support?
Neutral
How was the initial setup?
I was not involved in its deployment.
What was our ROI?
It is hard to say, but the value is there. At the end of the day, the benefits of having a failover solution outweigh the cost.
Which other solutions did I evaluate?
I did not participate in the evaluation of other similar solutions.
What other advice do I have?
Overall, I would rate Zerto an eight out of ten. We are interested in the technical abilities that it offers, but we would like to see an improvement on the support side.
Great interface, easy to use, and simple to update
What is our primary use case?
The primary use case is disaster recovery.
How has it helped my organization?
The biggest benefit is the application-consistent disaster recovery functionality.
What is most valuable?
The most valuable features include the ease of use and the usability of the user interface. Long-term, the solution has proven to be very resilient and stable. It meets our DR needs for VM environments.
The near-synchronous replication is a great feature. You have near real-time DR capabilities. In the years I've used it, we've had application-consistent profiles. To meet the recovery point and recovery time objectives, it helps to have that on hand.
It's affected our RPOs positively. It totally meets them via near-synchronous replication. That means the VM stays in a consistent state and is always available.
What needs improvement?
Zerto could improve its reporting capabilities. That's lacking. The alerting capabilities are lacking as well, partly due to the fact that there's no way to trim down the alert fatigue if there are failures within the application. It will send out alerts consistently instead of spreading the alert times every 30 minutes, hour, et cetera.
For how long have I used the solution?
We've been using Zerto at our organization over the past eight years.
What do I think about the stability of the solution?
The solution is very stable.
What do I think about the scalability of the solution?
I cannot comment on scalability. We only have two Zerto instances installed, one in production and one in DR. We haven't had to scale out or to the cloud.
We are protecting upwards of 100 virtual machines.
How are customer service and support?
Zerto's support is good. They are responsive from an email perspective. I've never had to pick up the phone to call them for anything beyond our DR testing every year. In those cases, we do open a proactive ticket in the case that we run into issues with recovering virtual machines.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We did not use any other solution previously. We chose Zerto since it was an application we inherited. It wasn't something I specifically chose, however, understanding the industry, we know that it is the top player in terms of software recoverability for virtual machines.
How was the initial setup?
I did not initially set up the solution; I inherited it. However, over the past eight years, we have gone through a number of upgrades, which for the most part have gone seamlessly. We did have a few issues in the past that support was able to fix in a timely fashion.
What was our ROI?
I'm unsure if the company has witnessed any ROI. We have not gone through any TCO analysis.
What's my experience with pricing, setup cost, and licensing?
The licensing is outside of my purview.
What other advice do I have?
I'd rate the solution nine out of ten. If the reporting and alerting functionality were better, I'd rate it ten out of ten.
Easy to use, quick to understand, and simple to set up
What is our primary use case?
In my previous company, we used it for recovery. We'd use it for annual DR testing. At that point in time, I was doing recovery for a few customers in government, financial, and other institutions.
What is most valuable?
It's easy to use. It wasn't too difficult to start with. With most vendors, initially, you have a learning curve or configurations. In this case, Zerto was quick to understand. The dashboard was easy and the UI was simple. The experience is comparatively good with Zerto.
The near-synchronous replication has not been used much. That said, it does help when talking about storage layers. The availability of the VMs is good. In terms of resiliency, there are a lot of benefits to it. Most have a recovery of 24 to 48 hours; Zerto has gotten recovery down to four hours.
We've done a POC with a DR to AWS. It was limited, however, it worked well and there was support. We didn't run into any challenges.
The effect on the RPOs has been excellent. It's been impacted greatly. Customers enjoy the shorter timeline to recovery. The customer confidence is high.
What needs improvement?
Now, everything is moving to the cloud and many modern app solutions are based on virtualization and cloud, however, for situations where Unix platforms are used, we'd like them to be able to support that.
For how long have I used the solution?
I've used the solution for almost five years.
What do I think about the stability of the solution?
The solution is pretty stable. Sometimes there may be bugs, however, so far, I haven't personally found any bugs beyond the initial setup.
What do I think about the scalability of the solution?
There is a wide range of scalability with different storage solutions.
We've deployed Zerto with 40 TB of storage layers.
How are customer service and support?
Technical support is good.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We used NetBackup and v-Motion. I'm familiar with Commvault and Veeam, which is also a fast solution.
When we used VMware V-motion or other methodologies, with Zeto, once you have your SAN hooked up well and your networking component set, then you failover to the recovery. With Zerto, the recovery times were less compared to what we witnessed with our previous traditional methods.
How was the initial setup?
I was involved in the initial deployment. My job was to get Zerto up from scratch and make sure the configuration, network, storage, et cetera were up and running. It's fairly simple. There's a learning process, however, once you know it, it gets easier.
What's my experience with pricing, setup cost, and licensing?
I'm not involved in the licensing process.
What other advice do I have?
I'd rate the solution nine out of ten.
Good for protecting VMs, has useful, near-synchronous replication and helpful documentation
What is our primary use case?
I use Zerto for disaster recovery.
How has it helped my organization?
The time it takes to fail a server over to DR has been great. We've seen a reduction in time spent. We can do it in minutes. Being able to go back to certain snapshots, to failover to another location, and then go back to specific snapshots is quite useful. We can roll back easily.
What is most valuable?
The off-site replication is excellent. We have workloads that aren't DR-aware. Being able to replicate it to other data centers is great. We don't have another way to do it, currently.
The near-synchronous replication is good. You get five-second data points. It's not something we advertise to our customers, the developers, however, we've had instances where we needed to go back two hours, prior to a file being deleted, and it's helped.
We're protecting our VMs with Zerto. It's positively affected our RPOs. It meets the objective. It's the only way we can have a solution for certain applications where we send an entire application to another data server.
What needs improvement?
It's a great product. There are a lot of features that it has that we don't use since we are on prem. We strictly use it for DR between our data centers. There are a lot of cloud plugins that they have that we don't use. Our use case is limited. It does everything we need it to.
For how long have I used the solution?
I've been using the solution for probably four or five years.
What do I think about the stability of the solution?
The stability of Zerto is good. We didn't have any issues. Our biggest challenge was trying to get to the clients and I was waiting on an upgrade path - from Windows to Linux. Now there is an upgrade path. Honestly, that has been the biggest challenge we've had for five years.
What do I think about the scalability of the solution?
The scalability of Zerto is good. You can easily protect other clusters and VRAs. It's very flexible.
Our current environment has 45 VRAs in each cluster. We have two replica pairs, two sites that mirror each other.
In total, we have 70 ESX hosts.
How are customer service and support?
Technical support is great. They've shown us many things about the manager that we didn't know about. Every time I call, I take notes. They are very knowledgeable and the knowledge-based articles on the site are also helpful. Even if I thought something was broken, they've always managed to fix it.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We used to use VMware's SRM. With SRM, for us, it was overly complex. We used an array-based replication with SRM. We had issues where the storage team would go to do work on the array and they would fail the machine over and it wouldn't be right. We would have outages. Every time we did a failover it was a process and we would be missing rules.
This is not array-based and we can test our failover in a sandbox without taking the system down.
How was the initial setup?
The initial deployment was easy. We deployed VRAs to the host from the manager. It works very well. The amount of VRAs you have to deploy and the amount of time it takes is minimal. It took us about an hour.
What was our ROI?
I can't speak to if the company has witnessed any ROI.
What's my experience with pricing, setup cost, and licensing?
I don't follow the licensing. It was bought for us and we use it.
Which other solutions did I evaluate?
We evaluated SRM and a few others. I can't remember which ones we tested. We've been on Zerto since version six.
The selling point for us, coming from SRM, is that SRM was tied to vCenter. We had to pay attention to versions and there were a lot of ways you had to make sure the versions were correct and it was overly complex for what we needed. We simply needed to replicate a virtual machine and that was it. Zerto stood out as it was easy.
What other advice do I have?
I'd recommend the solution to others. I'd rate the solution ten out of ten.
Easy to use, fast, and good near-synchronous replication
What is our primary use case?
We use the solution mostly for disaster recovery, however, we use it a lot for VM migrations and data center relocations.
What is most valuable?
The ease of setting up replication, the speed, and the ease with which I can fail over and fail back are all excellent aspects of the solution.
We've used Zerto for failing over and moving a lot of workloads from one location to another during v-center upgrades, during data center relocations, et cetera. We even had a case where we had a need to move over to our DR data center, however, in the middle of running there, our DR data center started having thermal issues, so we had to bring everything back. Zerto made that super easy.
Previously, we were using SRM. In the case of the thermal event, SRM would probably have taken, I'm guessing, an hour or two to do the failover. With Zerto, we were able to get everything moved over in about 15 minutes, and it was roughly 150 or 200 VMs that we did in that time period.
The near-synchronous replication works. It's very quick. I like that I can fail something over and not lose any data. That's pretty important. We want to not lose data. As a healthcare organization, losing patient records would be a very bad thing.
It's important to have DR in the cloud right now. We're looking at leveraging AVS for our DR site for the sake of not having to run our own data center. Leveraging the cloud is super important. It will help us to get away from on-prem and not even have to deal with a co-location facility. The reliability will be important. There is also the impression that there is going to be money savings around that.
It's had a positive effect on our RPOs. Overall, the RPOs have gotten better. Every aspect compared to where we were with SRM or prior to that, Zerto has improved. It's a lot easier to manage Zerto as it is hardware agnostic. It helps get things failed over and protected quickly. Every aspect has improved with Zerto.
What needs improvement?
Some of the ability to automate selections and automate VPG creations could be better. We've been building out a lot of new V-centers lately, and new data centers. Whenever we create a VPG, we generally set some very specific settings. If there was a way to set a template or a blueprint, to say that if I'm replicating to a data center from here, these are always going to be my default settings. That would be ideal, instead of having to manually set everything every time.
There are a few issues we've had with Zerto where it doesn't behave the way we want it to. I'm being told it's by design. Therefore, it's not an issue per se, it's by design.
For how long have I used the solution?
I've been using Zerto for three or four years.
What do I think about the stability of the solution?
I've had no problems with the stability. There have been a few bugs along the way, however, Zerto has been very quick to work through them.
What do I think about the scalability of the solution?
We have 1500 to 1600 VMs protected with Zerto and most of our DR strategy is being built around Zerto.
I can't speak to scalability. We've been steady-state since we implemented it. It's been protected by the same workloads since then.
How are customer service and support?
Zerto support has gone downhill recently. When we first started, they were great. However, after the HP acquisition, the quality of support is not as good. The knowledge has dropped and the time to respond is slower. I seem to now get people who ask basic questions that I already answered when I opened the ticket.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
Previously, we were using SRM. SRM was a nightmare. Zeerto has been drastically better.
What's my experience with pricing, setup cost, and licensing?
The pricing is expensive. However, I definitely see the value and my corporation sees the value.
Which other solutions did I evaluate?
We did look at Veeam and were using SRM in the past and Zerto seems to be the most full-featured and the easiest to implement. It's also the most powerful overall. Veeam isn't even close to what Zerto can handle right now.
What other advice do I have?
We're mostly on-prem, however, we've started doing DR into AVS - Azure VMware Service.
I'd rate Zerto eight out of ten.
