HPE Zerto Software Reviews

We use Zerto for offsite disaster recovery. We have over 70 VM servers, several of which are our mission-critical servers that are replicated to our VMware hosts at an offsite location. 

We also replicate our Citrix environment and Disaster Recovery Zen App servers with Zerto to our offsite location as well. Most of our servers are Windows-based operating systems. However, this doesn't matter because we are replicating the VM servers. Further down the line, we may invoke extended retention for some of our more important servers.  

It gives us peace of mind that our data, servers, and environment are protected. We can easily restore VMs quickly and have confidence that the replicated data will be current. 

We are able to show proof in tests, reports, and live data to our owners, showing that our most sensitive data and servers are being replicated to an offsite facility, and we can restore it in case of a natural disaster or from our system being compromised by ransomware. 

Our IT staff can easily navigate through Zerto and test failover, see if there are issues with replications, and create offline copies of the data. 

Being able to test our VPGs and prove that our disaster recovery setup is in place and functional. 

Our business owners can be assured that our data is protected, and in case a serious problem occurs, they know that we will be able to recover easily. 

Zerto is fast to restore our mission-critical servers when needed. We also use Zerto to make copies of our VM servers for our offsite Citrix Zen App Servers. Zerto has helped simplify the process of disaster recovery setup and made the tasks more efficient for our IT Staff.

Zerto could add text alerts if there are critical problems and alerts if changes affect our replication. We do receive emails, and they will alert us to issues that we are having with VPG SLAs. 

I don't have any complaints about Zerto, and I hope they continue to develop new features. If they had classes on using Zerto, that would help with onboarding new IT staff. They may already have them, and I am not aware that they do. Overall, Zerto works out great, and they do a good job. 

I've used the solution for five years.

The primary use case is disaster recovery. 

The biggest benefit is the application-consistent disaster recovery functionality. 

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. 

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. 

We've been using Zerto at our organization over the past eight years. 

The solution is very stable. 

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. 

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. 

Positive

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. 

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. 

I'm unsure if the company has witnessed any ROI. We have not gone through any TCO analysis. 

The licensing is outside of my purview. 

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. 

We primarily use the solution for disaster recovery. 

We set up the environment and we're testing right now. We are able to do test recoveries and restalls. Once we have everything set up, we'll try a real failover test. 

The DR - Disaster Recovery - is the main selling point. We have a policy that requires us to have, in case our primary goes down, a failover for our production environment to another site. 

The near-synchronous replication is very good. You can set it to a second. It's important to our company. All of our applications are a part of our production. We need to have uptime. We have an SLA that meets uptime requirements and needs to stay up to maintain our company reputation.

We are also protecting our VMs. 

It's had a positive effect on our RPOs. It's meeting our objectives.

The journal history is only up to 30 days. If it were longer, it would be better and I would have more flexibility.

I've been using the solution for a little over a year. 

The stability is great. It is running well. 

The scalability is not too bad. We upgraded our server and we were able to scale easily. We installed Zerto on our VMware with no problem. We have about 200 VMs and Zerto is protecting about just under 100 of them. 

Technical support is an area I'm not too keen about. My experience is 50/50. Level one support doesn't seem very knowledgeable and I don't get the answers I want. That can delay us sometimes. Hopefully, they will improve. 

Neutral

I was involved in the initial deployment. 

The process is not too bad. The process was pretty straightforward. 

The vendor provided implementation support. 

We have noted an ROI. Compared to others, overall, it made sense to choose Zerto.

They are not cheap. They are more expensive than others. However, they have great features.

We did test other solutions. The speed of recovery in comparison testing was great. That was the reason why we chose Zerto over our competitors. 

We looked at Veeam Orchestrator and Veeam is not as complete in terms of DR. 

The ease of use of Zerto and the interface are easier to understand and use.

I'm not sure which version of the solution we're using. It's around version eight. 

I'd rate the solution eight out of ten overall. 

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.

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. 

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.

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.

I have been using Zerto for about five years between multiple organizations.

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.

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.

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. 

Positive

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.

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.

It was a little before I joined the company, so I cannot comment on the solutions they evaluated. 

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.

I am a part of the disaster recovery team. We manage Zerto for our customers. We perform business-as-usual tasks such as installing Zerto or implementing Zerto for VMware infrastructure and if needed, for cloud infrastructure. We manage Zerto on a daily basis. We create the VPG, add virtual machines to the replication, operate Zerto to perform maintenance, and so on.

We use Zerto for live replication. It is real-time replication that takes around a couple of seconds. We don't use long-term retention or backup. We perform failover tests and live failovers as well.

Our customers are mostly satisfied with RPO, which only takes a couple of seconds. It does not cause big problems. It usually takes a couple of seconds. You do not have to perform any specific actions to keep it running because it mostly runs by itself and even resolves some of the issues itself. Zerto is very much related to VMware infrastructure. If VMware infrastructure is running fine, then Zerto runs fine as well. Zerto itself does not cause any problems.

I cannot compare it with others because we are mostly using Zerto, but we are very satisfied with it because within a couple of minutes, or even seconds, we are able to recover a VM or multiple VMs. Other recovery systems might work similarly.

Its ease of use is valuable. You do not have to do much to install Zerto or implement Zerto on the infrastructure. It is not very complicated. It does not have large requirements. There are mostly network requirements. It is required to be connected to two sites or more, and then you just install Zerto Virtual Manager. You also install virtual replicators on the ESXi host and perform replication of VMs.

I do not have any specific ideas right now. I know they moved to the appliance version with Zerto 10, but I do not have much experience with that because we are still using Zerto 9.5 and 9.7. The appliance will be faster and more secure. It will be good.

I do not need any additional features. The replication is real-time. We are very satisfied that this is happening all the time. We do not have to touch anything. When we implement it in a proper way, everything works fine. We just let it be.

I have been using Zerto for around two years as an engineer.

If the VMware infrastructure works fine, then Zerto works fine. I have only observed a couple of issues, but usually, Zerto Virtual Manager and VRAs work fine. They are not very problematic.

I do not have much experience with scalability. One of the customers has eight vCenter servers, and each one of them has Zerto implemented. They are all connected with each other, so sometimes replication goes to a couple of vCenters. Another customer has only two vCenters but with a large number of ESXi hosts in VMs. There are around 500 VMs that we have in production for one customer. 

I have contacted their support multiple times. They are quick to respond. They are happy to help. They are happy to connect by Zoom to have a session to share the screen. I am satisfied with them so far. I would rate them an eight out of ten because not every response is as we expect. They do resolve the issue, but sometimes customers have unusual questions, and they are not able to say how exactly to fix that or how to do something, but overall, it has been very good.

Positive

I have implemented Zerto from scratch on the infrastructure. In most cases, I am not configuring the network. There are other engineers to do that, but if the network is working and I have all the information I need, then installing Zerto Virtual Manager and Virtual Replication Appliances (VRAs) is very smooth and simple.

If everything is configured as it is supposed to be, it does not take long. It also depends on whether you need to deploy a Windows VM or appliance. If you need to deploy an appliance, it will take a little more time. Deploying a VM and installing Zerto Virtual Manager and VRAs takes a couple of hours.

I would rate Zerto a nine out of ten. There is always room to improve, but I do not have anything specific that can be improved.

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

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

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

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

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

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

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

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

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

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

We have about 700 servers and 130 VPGs.

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

Positive

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

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

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

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

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

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

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

We use it for storage and replication. In our organization, our team is responsible for the disaster recovery process.

Before, we were able to test about 16 virtual machines in production. Now, we can do the same exercise with 180 virtual machines, in less time. And previously, we needed our whole team to execute the manual process with Hitachi. Now, we use half that number of personnel in this exercise.

The speed of recovery is definitely better with Zerto versus the previous mechanisms we had. It has helped to reduce downtime without a doubt. On two occasions when we used Zerto for recovery, we reduced the downtime by about 80 percent.

We had an issue with change configurations in a database and we couldn't roll back those changes. We used Zerto to recover the state of the virtual machines to 10 minutes before the changes.

It has also exceeded our expectations when it comes to RTO.

The replication and recovery features are the most valuable. We have been able to recover files with Zerto. First, we enable the virtual machines on the recovery site and then we navigate to find the file that we need. On two occasions, other departments in our organization reported issues with specific virtual machines. We used the checkpoint feature of the Zerto to enable the recovery of those machines to a point that was a few minutes prior to the problem.

It's an excellent tool for the replication of VMs.

We had some issues with replication, especially on Linux, but we have already resolved them.

I would like them to enable more backup configuration features. I'm not sure if Zerto can give us immutable files for ransomware protection. That could improve the backup.

I have been using Zerto for about two years.

The stability gets a high grade from me. I don't recall any issues.

Our principal site is located in one city and the recovery site is in another city. They are connected by an extended LAN.

In terms of scalability, it is good because, on the two occasions that we have done the upgrade process, they were "hot," meaning we didn't need to turn off our servers and that's very important for us. We always have our tools available.

We have opened cases on several occasions for update processes and for issues that we had at a moment when we were doing an exercise and replicating a VM to the recovery site. Their response was immediate and they were very efficient in coming up with resolutions.

Positive

We didn't have any previous backup solution.

The pricing is a little more expensive in comparison to other tools.

Knowing the backup options that Zerto has, we could be using it to back up our entire company's virtual machines, but we are just using its replication and backup for some virtual machines, but not all of them. That's because we are limited in terms of our license. We are only replicating about 30 percent of our virtual machines, those that have been identified as the most important for the organization.

We checked out Veritas Risk Advisor and Veeam.

It is meeting our RPO expectations and we are happy with the RPO.

We have previously used Zerto for data center migration projects. We have another data center migration coming up within the next year where we will be using Zerto as well.

We had pretty strict requirements when it came to cross data center migration capabilities. We wanted to ensure that no plugins or drivers were needed. We also wanted a simple deployment. Zerto very easily fit that bill.

The most valuable feature is Zerto's ability to synchronize data to the remote destination prior to the actual live migration date. This saves a massive amount of time during the actual migrations, and has been extremely beneficial. Having the data already synchronized on the evening of the migrations makes the final moves fast, easy, and seamless.

The interface is very easy to use. The product is easy to understand. We have had great success in using it for migrations. The benefit for us has primarily been the ease of use and stability of the product.

The VPG model has caused a bit of a concern. We are considering using Zerto to replace Site Recovery Manager. SRM is very easy when we have entire data stores being replicated. We don't have to make any decisions when it comes to groupings of VMs. If we move to Zerto, which we are considering, we will have to work closely with our applications teams to create VPGs and determine how the VMs will be grouped. This will probably be beneficial in the long term, but short term it will create more work for our team.

I spoke to a Zerto engineer who mentioned that we could do a VPG at the cluster level and a VPG at the datastore level. However, the one issue we've seen with VPGs is if the synchronization fails the entire VPG has to be recreated. Even though we can cover our environment at the cluster level or datastore level, that wouldn't be ideal. We really need a simpler solution for DR that will cover all of our VMs at once, instead of spending a considerable amount of time on VPG creation. 

We have been using Zerto for about three years.

The stability is very good. All of the components that we set up for Zerto have been very stable. 

Scalability has met our needs.

Support has been excellent. We had a couple of issues initially with a VPG that wasn't functioning properly. Support was very quick to respond. They were able to assist us and resolve the issue very quickly. We have only had to call support one time.

Positive

We also use Site Recovery Manager. SRM does not have the same feature set for migrations that Zerto has.

The product was easy to deploy. At the time, the only thing that we wanted to improve was to have an appliance for the ZVM, instead of a Windows server. I understand an appliance is available now. This will be very beneficial in the future.

The deployment was straightforward. We basically went through the documentation and then had a planning meeting with Zerto. Once we understood all of the requirements we were able to deploy very quickly with really no issues at all. We deployed Zerto in less than a week.

We implemented the product ourselves. Zerto's expertise has always been very good.

Our migrations were all successful. We had no issues at any point during the project. That is what really sold us on Zerto.

The licensing costs are not cheap. It is an expensive product. However, you do get what you pay for.

There was really no other product that compared to Zerto. Zerto had exactly what we were looking for in a data center migration product. It had the ease of use and interface that we were looking for, that is, very simple and straightforward.

Zerto's ability to copy the data first, then synchronize just prior to the migrations made it much faster and easier for us to use than other solutions.

Understand the VPG configuration. Understand that you will need to make some decisions as to how to cover your VMs. We eventually went with one VPG per VM for our migrations. This is because we discovered if the VPG has a problem, then you need start over and recreate the VPG. If you choose to cover 50 VMs on a VPG, and if that VPG fails for some reason, then you need to restart the whole process. So you need to consider your VPG design and how you are grouping your VMs.

We haven't used it yet for disaster recovery, but that is something that we will be looking at over the next year.

We have had great success with the product. It is one of the very few products that we have recently used that literally had no issues and worked exactly as designed. At every single point in our migration, it was successful. We had multiple migration waves that occurred over a period of a year and a half. We literally had no failures during that entire time, which is of rare in the industry and made us very happy. Now that we have another data center migration project coming up, we decided we were just going to go straight back to Zerto.
