HPE Zerto Software Reviews

We use Zerto primarily as a cloud provider to set up either ground-to-cloud or cloud-to-other cloud sites for disaster recovery. 

We also use it as a migration tool to get people's virtual VMs from ground to cloud. 

Another use case is to protect our virtual machines in our environment. We have our own internal IT, and we protect them with Zerto, but the vast majority, probably 98% or 99% or even more, of what we do is with customers since we're a cloud service provider. As a service provider, we're not classified as an MSP. We do resell Zerto to our clients.

What I appreciate about Zerto is the speed to recover. We have two ways that we migrate them into the cloud: one is with Zerto and one is with Acronis. Acronis is a bare-metal restorer that takes much longer to do the restore, depending on the size of the VM. 

I appreciate that Zerto already has the disk synchronized to the cloud, and it just updates deltas every five seconds or so. Should there be an instance, such as a migration, or if the customer has been ransomed, or if they want to roll back for any reason, they can do it because we have their data in the cloud. 

When I was an IT manager, our RPO and RTO were measured in hours or days; now it's measured in minutes, which is huge for disaster recovery. 

The interface and ease of use of Zerto make it easy. We're getting into version 10 now. The version 10 update 4 took really long to deploy, and we had to back off and do update 2 because that seems to deploy much quicker. 

Other than that, it's pretty easy to deploy and manage; we can set it up through Zerto Cloud and update it remotely. 

I see the benefits of Zerto immediately after deploying it. As a former IT manager, when I saw what it did, it was a revelation, and I thought this is excellent for disaster recovery. Zerto's near synchronous replication is fantastic. It helps our RPO and RTO and is beneficial all around. In terms of RTO and RPO, Zerto improves them to seconds. It indicates right in the health of the VPG how many seconds the RPO or RTO is. 

Our DR testing with Zerto is much quicker. We encourage our customers to do testing so they get familiar with recovery processes. We maintain a playbook and a method of procedure, and every test adds something new to the MOP, improving how quickly we can resolve any disaster. 

Zerto has a significant impact on our IT resiliency strategy. We do it for customers, making all the difference in the world. It's not just about me as an IT manager using Zerto; as a service provider, we host people's data in the cloud for disaster recovery, making instantaneous recovery possible that wouldn't be as quick otherwise.

In terms of improvement, Zerto does reasonably with support and responds quickly to help us. I don't know if there's anything they could do better, but we'd prefer Zerto to work with our open cloud product for disaster recovery and migrations. So far, they haven't made their product compatible with KVM, and we would appreciate seeing that.

I have been using Zerto in my career for four years.

I haven't seen much instability with Zerto; it seems pretty stable overall.

Zerto scales efficiently; we have hundreds of hosts, with production and disaster recovery environments. We set it up to replicate, such as from Grand Rapids to Indianapolis or Detroit, so it scales pretty efficiently.

Zerto's support is reasonably good. If they know I'm on the call with a customer, they usually join a Zoom session quickly to help resolve issues. Sometimes it's resolved quickly, while other times it may take two or three sessions, but they're generally pretty good.

I use alternatives to Zerto, as I'm a Veeam engineer certified in Veeam. We use Acronis and Cohesity, but in my opinion, there's nothing that works for disaster recovery quite like Zerto. The main differences between Zerto and Veeam are ease of use and convenience. 

Veeam allows a restore of a server in a test environment while detecting any malware before connecting to the network, which I haven't seen in Zerto. Zerto just replicates what's there without evaluating for malware. Zerto is quick and easy to use while Veeam is more complicated but has more capabilities for backup. I haven't greatly used Veeam's continuous replication feature, but from my experience, Zerto is easier to set up and use, and it's less expensive as.

When I first deployed Zerto about four years ago, it took about 15 to 20 minutes to set up after the client had a Windows server ready. We'd give them the installer and set it up, then pair it with their hosts. After installing the VRAs and setting up the VPGs, once the first VPG is set up, we can do the rest without client involvement. Overall, the total time ranged from half an hour to 45 minutes, depending on how many they wanted to set up initially.

I'm a Professional Services Engineer, which means that I implement projects. When our salesman sells disaster recovery with Zerto to a client, I'm the one who sets it up, creates the VPGs, and ensures all the syncs work properly; the long-term maintenance is handled by another team.

Zerto has a significant impact on our IT resiliency strategy. We do it for customers, making all the difference in the world.

Zerto is easier to set up and use, and it's less expensive.

We use alternatives such as Acronis and Cohesity.

The recovery process depends on the customer. Zerto is one of those things that we set up and monitor, but if the customer isn't monitoring their VMs, it can complicate things. 

We had one customer who made a decision to protect only a few of their VMs and then got hacked, which wasn't Zerto's fault or ours; it was their decision.

However, for customers that have everything protected, we've had quite a few successful recoveries. There have been situations involving ransomware or data recovery situations when we used Zerto. I haven't personally been involved in one, but our company has had multiple incidents where we were able to recover without paying the ransom.

Zerto does require maintenance on our end. We register the client in the cloud, and if they move away from us, we unregister them and remove their tenant. We also have updates to do, including the Zerto virtual manager and the virtual replication appliances on the hosts. With hundreds of hosts and multiple data centers, we have a lot of work to do, which is why we have someone dedicated to updating Zerto. 

On a scale of 1-10, I rate Zerto a 9.

We use Zerto at a very large public sector undertaking in India that manufactures power equipment. 

It is being used for continuous data protection, replication, and recovery. We have a consolidated data center in Hyderabad, India, and we are replicating the data to another data center in Hyderabad. For replication and continuous data protection, we are using Zerto between both sites.

It simplifies management. The console provided by Zerto is very simple to use. With the click of a button, we can do the failover and failback.

It helps with business continuity. We can easily failover from one site to another and back. We are able to do most of the operations very easily.

It does asynchronous replication. When the data gets modified in the main data center, the modified data is immediately replicated to the other data centers. It helps to maintain minimum RPO in seconds and the RTO in minutes.

We have a number of virtual machines for databases, application servers, web servers, Internet servers, and proxy servers. We are using Zerto for the complete replication of these VMs to the other data center.

Our RPOs are in seconds, and our RTOs are in minutes. That is critical for the applications. Earlier, we were using another replication software from IBM. We did not get the same RPOs and RTOs. Zerto is helping us a lot in preventing data loss. The data loss is minimal. It is only in seconds. This is a very important feature of Zerto, where it maintains RPOs in seconds and RTOs in minutes.

In November 2024, we faced a ransomware attack. With the help of Zerto, we were able to identify the journal entry that was malicious. Zerto gave us an alert, and we were able to identify the clean copy by going backward. We went back a few seconds. It maintains journal entries every five seconds, so we were able to identify a good copy of the data. We were then able to do the failover. Because of Zerto, we had minimal data loss. We were able to identify a good copy of the data and do the failover to the main data center.

With Zerto, we have become more resilient and scalable. We were able to scale from a few VMs to about 250 VMs. Our scalability has improved a lot because of Zerto. The ransomware resilience feature has made us more resilient. We chose Zerto over VMware Site Recovery Manager because VMware Site Recovery Manager did not have the ransomware resilience feature. In November 2024, when we faced an attack, with the help of Zerto, we were able to recover within seconds with a minimum amount of downtime. We were up and running quickly.

The features I find most beneficial about Zerto include continuous data protection, easy configuration, and simplified management with a user-friendly interface. We were able to configure it easily for our needs. Continuous data protection between our two data centers is also valuable.

I also like its scalability and flexibility. We have scalability from a few virtual machines to more. We can increase the number of VMs according to our requirements. Zerto scales very easily with our increased number of VMs.

Zerto also provides ransomware safeguards. While doing the continuous data replication, Zerto creates journal entries. When the data gets transferred to the other site, Zerto checks whether the replicated data is malicious or clean. If it is a good copy, it makes a journal entry. If there is any malicious code, it immediately gives an alert. We are very happy with this ransomware protection feature of Zerto.

Its pricing could be better. Also, Zerto needs to improve its reporting capabilities and provide better dashboards. A number of times, I had to contact Zerto for more reports. They are very customer-friendly. They helped us and gave us some customized reports, but its reporting capabilities could be better.

I have been using the solution for about two years.

It has improved scalability significantly. I was able to scale from a few virtual machines to about two hundred fifty virtual machines.

The support team is very customer-friendly. When I raise a ticket, they respond quickly with minimal waiting time. I often get a call within half an hour. Their customer support is reliable and fast.

Positive

Previously, I used some other replication software from IBM but did not achieve the desired RPOs and RTOs. This led me to choose Zerto.

The deployment was very easy. With a few clicks, we were able to configure Zerto for both of our data centers in Hyderabad. It was very easy to configure. It has a very intuitive classical user interface. The configuration was done with minimal clicks.

In about one hour, we were up and running with the first replication. We were able to do the first replication within an hour from our main data center to our secondary data center in Hyderabad. It is efficient and reliable.

Its maintenance is being taken care of by Zerto.

I am the main database administrator, and two of my colleagues also participated. Three of us were involved.

Zerto is definitely more costly compared to its competitors, such as VMware Site Recovery Manager. It may not be suitable for small and medium-sized industries.

We considered VMware Site Recovery Manager but did not opt for it because it did not offer the ransomware resilience feature like Zerto.

Overall, I would rate Zerto a nine out of ten. The software is exceptional in terms of continuous data protection, resilience, scalability, agility, and ransomware protection.

My original use case was to protect against ransomware and any critical failure in our infrastructure, and that has been carried through to the present day.

It is incredibly easy to use, which attracted me to the product. I have been doing IT for over 30 years, so it did not take me very long at all to learn it. That is a good thing because when you have a solution like this going in, you want to make sure that you are fully confident with it within a short period of time. The learning curve for this solution was very short.

Zerto’s near-synchronous replication is good. Previously, when I tried to do it at a SAN level, which was part of the SAN vendor's portfolio of solutions, I could never get it to work. It was not very user-friendly. It was complex and difficult to configure. In comparison to that, Zerto shines.

Over the years, they have brought in immutable backups. They have brought in cloud migration, though I have not used that due to the nature of the Azure tools I use, but I have used immutable backups. In the past, we replicated from our on-prem site to our data center, and then more recently, we replicated from our on-prem site to Azure. The next stage is to replicate from Azure to another part of Azure or another region.

Zerto has had a very high impact on our RPOs. The recovery is very fast. It is instantaneous. We have already got everything replicated on our remote site, so we can just fire it up. All we have to do is follow through the scripts to change it over.

Previously, our RTO was very much in the order of two days. After we implemented Zerto, it is in the order of an hour.

We put in Zerto in response to ransomware because I had to do quite a lot of manual jumping around. Hopefully, we shut the gate on that problem. We have a solution to utilize.

We are a small to medium organization. We did not do downtime testing before we had Zerto, but now we do. It gives me the ability to test. We never had that option of testing. Usually, you cannot test the system in real-time because you have to turn off the live, whereas Zerto allows you to do it with different VLANs, etc. We can spin it up and effectively test it out. If I was doing a manual test, it would have probably taken me two or three days. I can do that in maybe 15 minutes. There is a 20 to 30 times improvement.

Zerto has had an effect on our IT resiliency strategy. It has supplemented where we did not have a tool before.

The ability to test that my backup regime is actually doing and working as I want it to do is valuable. It provides visibility and comfort. I can see in real-time that things are replicating, and my SLAs for my RPO and RTO are available instantly. That gives a lot of comfort. It is the sort of thing that gives you peace of mind.

Some of the cloud instructions around VNets and peering of networks could be clearer with some best-case examples. It is more complicated once you move into the cloud than running it on-premises. Actually doing these things is quite easy in the cloud and with Azure, but understanding how it fits in my environment can be quite a head-scratcher at times.

I started using it in early 2016 and have continued until the present day.

I would rate it a ten out of ten for stability. I never had a problem with it.

It has been fine. It has grown with the business as we changed things around. It has been very flexible. I would rate it a ten out of ten for scalability.

Their support is pretty good.

Positive

I used EMC SAN. Zerto is 400 times better. The previous one just did not work. I bought the SAN with the intention of having recoverability with it, and I could never get it to work. There was relatively zero support. It does not encourage us to persevere with it. We just ended up using it as a SAN and moved over to another solution.

We currently have a hybrid setup because we cannot migrate in seconds. It takes quite a long time to pick a network and move it into the cloud. It is not as easy as you would hope when you start moving into the cloud. There is a bit of complexity. If you have a network with multi-subscription, multi-network, VNETs, and peers, it takes a little bit longer to try and figure out how to make it work.

Initially, when I first put it on-premises, it took me about a day to get it working. In the cloud, it took a few days to head-scratch through it.

It is currently running between on-premises and Azure cloud. We do not split by department. We are not big enough to do that. We run a centralized compute function for the entire business, so it is relatively straightforward and flat as a design. Everyone uses the same environment.

It is used by only IT people. There are six of us in IT, but only three people use it with me being the primary person.

It requires a relatively small amount of maintenance. They have moved over to Linux-based machines, so we no longer have to upgrade them. We can apply a very simple process to update the actual version of Zerto. It needs a little bit of maintenance, maybe for an hour or so a month. I do the maintenance. I just keep an eye on it.

It is difficult to quantify that. I have seen no return on investment because I do not calculate around that sort of thing. If we had any disaster, we would have used it for real and would have seen a massive return on investment. It gives me peace of mind. If I am happy, then the management is happy.

Zerto has not helped reduce downtime in any situation because we have not had any downtime. Most people like me hope we never have to use it. It is like insurance.

It is not the cheapest product; it is not the most expensive product, but it works. It is a mid-range product, and it is justified in terms of being pretty quick and easy.

I would definitely recommend it, especially for people who have no current method of implementing a disaster recovery solution. It is a quick and easy fix, and I would highly recommend it.

I would rate Zerto a nine out of ten because we need a few more scenario examples when moving into Azure.

We use it for disaster recovery, replication, and backup.

We were able to see its benefits immediately after we deployed it. I used it to move sites. It is a good tool for transferring from one site to another. It does the configuration on its own and the site comes online seamlessly. You just have to commit to it, and it comes online and no one even notices it.

We create a job, which is a VPG, and we tell it to replicate it to another site. I live in Philadelphia. If Philadelphia gets attacked, we could shut it off and then go to the site that it replicated over and turn that on. It will just work as if nothing happened.

All the RPOs are less with our infrastructure because it is VM to VM in less than five seconds. We have never had a spike in our RPOs.

The recovery time of each VM is less than three to four minutes. Once we send a job over, it starts doing its thing. There is an auto-commit button, or we could time it to how much time we need before commitment. Once we bring up a VM and it reboots, we will see all the changes made, such as the IP address. If we go to DNS, we can see that the DNS entries have been updated with the new IP. We then commit to it, and it just comes back online.

Zerto has helped us reduce downtime. In just about five minutes, we are up. We had one incident with a Windows patch update to a server. The server could not come back online. We went in and recovered the VM right before it rebooted and got it back online. It had the same IP and other things, and everything was fine. Even though there was a slight downtime, we were able to get it back 100% before the reboot, and then we took off the update.

Zerto has saved us time in a data recovery situation due to a vendor mistake. We use a vendor for patching. The vendor accidentally mistyped something and took down a couple of servers because of this registry. We were able to get all the VMs back online. It took about three minutes per VM. When we used Veeam, depending on how much data was there, it took us about 45 minutes to an hour.

Zerto has reduced our organization's DR testing. We send it to a DR site from prod and then back to us. It goes from prod to DR and then DR to back in less than ten minutes. We did a DR move. We had about 15 VMs. We moved all the VMs to a different site. We then moved this actual site to a different location and then moved everything back. It did not take that long compared to Veeam.

Zerto has had a positive impact on our IT resiliency strategy. I have never had a problem. The product works very well. Their support is always active. They are willing to solve any problem that you have. Each time I have spoken with them, they have helped with every question to make sure our infrastructure is running well.

The most valuable feature for me is the replication. If I need to fail over sites, it can be done quickly, in less than five minutes. Each backup is implemented in five seconds. If we were attacked, I could revert to a backup from five seconds before the attack, and no one would know we were attacked. 

Once it is implemented with the vendor, they show you everything. Everything is very simple and easy. Replication and Restore are the buttons to focus on. It is all there with just a couple of clicks. It is simple. It is laid out simply so that you can understand it quickly.

I would suggest improving automatic updates. Their software requires updating level by level to keep it current. I was unaware that I was several versions behind, so I needed assistance to guide me to the current version.

I have used the solution for about a year and a half.

It only crashes if there are insufficient resources on my ESX box, which I discovered after overloading it with too many VMs. When the Zerto job tried to run, it crashed due to a lack of resources. I consulted with tech support, and we determined the solution was to move the main workload to a resource-available ESX box. After double-checking, everything has been running smoothly. Having good equipment ensures stability.

Scalability is tied to our vSphere environment. By adding more hosts and installing VRAs on each, tasks can be efficiently managed. Increasing the number of hosts allows for more VMs, depending on licensing. The bandwidth is also strong.

I would give their support a ten out of ten. I deal with support often, and online ticket creation yields a quick response. They understand what they need, and I provide it. They analyze the logs, suggest changes, and everything works well.

Positive

We used Veeam, which is more in-depth and requires extra steps for recovery. With Zerto, I just log on to the GUI and click what I need. For a live VM backup or replication, it takes just a few clicks, which led us to choose Zerto over Veeam.

Zerto is the easiest one that I have used. In terms of pricing, it is way better than Veeam.

Our MSP used Zerto to do a project for us. I was in the meeting looking at what they were doing. It seemed so simple to use. I asked them if they could compare this to Veeam, and they said that this is way easier than Veeam. With Veeam, you have to log on to the actual backup program. You have to go to the job that you are looking for and right-click it. There are about six steps after that, whereas in Zerto, when you go down on the bottom left, with just two clicks, a menu pops up, and then you are done with another three clicks.

It is on-prem. It is VM to VM. We are also thinking about a third solution, which would be on their site. Right now, we have VM to VM, but we have two NAS for hot and cold storage, so we are using everything that they offer at the moment, but we probably might head down more in the future.

The installation process was new to us as we started from scratch. After that, it was simple. Installing the VRAs involved pointing to ESX boxes. The NAS storage connection is simple; I just enter the IP address and credentials, and it links via SMB. I just create the job, point it to its destination, and it is ready.

Deployment was handled by one representative and me. I am also responsible for managing it.

In terms of maintenance, it requires manual updates.

Its pricing is way better than Veeam.

My advice to new users is to become more familiar with it. Once you start using it, it is easy to pick up and manage.

I would rate Zerto a ten out of ten.

Currently, my main use case for HPE Zerto Software is for failover. We have a site in Salt Lake City and another data center in Oregon. We fail over from this site to that site, verify, and fail things back. This is its main purpose as of today.

The feature of HPE Zerto Software that I appreciate the most is the ability to pick and choose what to fail over and when to failover. It is really easy to build a new zone and add servers, as well as remove them.

An example of how the features of HPE Zerto Software have benefited my organization was when we lost a circuit. We have a primary circuit from Salt Lake over to Portland and a backup one that runs through several different sites. We actually lost the main one and had to failover. Because most of the servers are in Salt Lake City, we had to replicate those back over to Portland because that is where they make the money. I had a few minor hiccups, but it was not our fault. It was just bandwidth, but we now have a larger pipe. That was a happy accident when we discovered why it was not going any faster - we were maxed out.

I find HPE Zerto Software to be pretty intuitive as it is, and I have nothing to suggest for improvement.

I have been using HPE Zerto Software for about four years now.

On a scale of 1 to 10, I would rate the stability and reliability of HPE Zerto Software at about 20. It just works.

HPE Zerto Software scales with the growing needs of my organization. The only issue I have ever encountered was when our developers grew busy and expanded their applications too quickly for licensing. That was resolved with a simple phone call. We received the new key by end of day after discussing how many additional licenses were needed.

I would evaluate customer service and technical support for HPE Zerto Software as exceptional. They listen first, then ensure they understand the problem before providing multiple solution alternatives. Having been in computing for almost 35 years, they are one of probably two or three companies that truly listen first.

I was using another solution to address similar needs prior to adopting HPE Zerto Software, but I am not sure what it was.

My experience with pricing, setup, costs, and licensing for HPE Zerto Software has been positive. The installers were knowledgeable and completed the installation correctly the first time. When we upgraded from VMware 6 to version 7, we needed to install a new agent. When it did not work initially, technical support quickly resolved the issue with specific instructions in just one call.

I have seen an ROI with HPE Zerto Software through faster recovery. We are getting closer to the five nines. Having the confidence that if something happens, our documented steps will work is invaluable.

I have personally used Veeam before selecting HPE Zerto Software, but having only been with the company for five years, I am not sure what solutions were used before that.

HPE Zerto Software is important to my organization because when performing replication, both systems remain functional during failover until the final switch. This results in virtually no downtime.

HPE Zerto Software has helped reduce downtime by at least 25% through faster recovery. For instance, if we lose an image, we can quickly recover it and power the VM back on, which is much better than retrieving a golden image that could take hours.

The solution has impacted my RTOs and RPOs significantly, saving me approximately two hours per day. It has also reduced our DR testing frequency from every other month to twice a year.

Regarding Cyber Vault solutions, the most important capability would be the ability to isolate a server immediately after a ransomware attack to investigate the incident.

My advice to other organizations considering HPE Zerto Software is to consider its ease of integration. It integrates seamlessly with various networks and works especially with HP infrastructure. The support from both HP and HPE Zerto Software teams is excellent.

I rate HPE Zerto Software 10 out of 10.

Right now, I am using it for disaster recovery and file recovery, with all the different components of it. It is just site-to-site replication from one site to another. I have done server moves, and I will also do server moves in a couple of weeks.

I use Zerto to help protect VMs in our environment. That is 100% of my use case. It helps us to commit to the recovery point as per our standards. Our RPO is under five minutes for everything I have got in there unless there is a sync happening at that point in time. It has greatly reduced RPOs and made them stable and knowable. 

Our RTOs are even better. We are also a Cohesity customer. Our tier one, two, and some tier three are in Zerto. For everything else, the plan is to bring it out or restore it from the backup in case of a DR or an event where there is an issue with the server. We know that bringing something online in Zerto is dramatically faster. It is a night and day difference. Restoring everything from the backup would take days or a week, whereas with Zerto, as soon as I make the change, everything will automatically come online at my other location. For example, I have a file server that is 50T. Restoring that from the backup took three or four days, whereas in Zerto, we can flip it over, and it would be up and running in seconds. 

Zerto helps us reduce downtime. If something happens and we need to bring a server up that is in Zerto, it will only take the amount of time required to commit and make sure that everything is functioning as expected, changing or updating IPs and names, and making sure that is good to go. It takes five to ten minutes. 

For auditing and other things, we can do a controlled VR test where we bring up all the necessary components in an isolated bubble with networking for just that bubble and bring it online. We can test SQL Servers, Exchange Servers, Active Directory, connectivity, authentication, and applications. We can bring it all online in that bubble while production is still going on without impacting anybody. In the event that we flip the switch and have to go, everything is going to work. In addition to meeting auditing needs, we have been able to refine the process so that in the case of an unfortunate event, we know we will be able to do it. We will be able to do it quicker than coming in cold and having never tested it or done it. 

Zerto has had a big impact on IT resiliency strategy. We know that as long as our boxes are protected by Zerto, we are covered. We will be able to spin a box up at our remote DR site and bring it online. It will be functional, and all the data will be there. It is not just about fulfilling an audit request; I sleep better at night knowing that we are protected, the data is there, and there are not going to be any issues. Zerto has near-synchronous replication. It works very well. I have been fortunate enough not to have to use it in a production environment, but I have used it to restore files. 

From the server moves, I know that I can cut over in a couple of seconds and all the data is there and ready to go. There is no lag. There is no waiting. I just have to update the IP and register that in DNS if the IP changes, and it is good to go. It is fantastic.

What I like most about Zerto is that it makes my job much easier. I have peace of mind knowing that it works. The replication time and the minor amount of time it takes to sync a new server outside of any of my huge 40-terabyte boxes is ridiculously quick. When I add a server, it is there in 15 minutes. I know it is protected. It is fantastic. There is peace of mind knowing that the workloads I put in there are protected. It is very easy to use. In day-to-day usage, it is very simple and easy to set things up or monitor it. I check it every morning and keep track throughout the day of what is going on and if there are any issues.

I am an advocate and a fan of the product, and I have had great success. The only negative I would give is that with the latest version of the appliance, setting up authentication was a bit of a challenge, but that is just a matter of using Keycloak and how things have changed. Other than that, I have had no complaints.

I have used the solution for seven years.

I have had no complaints. It has been running very well.

I have contacted customer service many times for various issues. Overall, they have been good, and I would rank them in the higher percentile of the support I have dealt with. Sometimes, I have had to get through a couple of techs or work solidly with somebody, or I have not fully explained the issue correctly. Once we get on the same page, the issue has been quick and easy to resolve. Nothing has hung up for too long. 

I would rate them a ten out of ten. I have never had an issue that was not resolved, and I have never been in a situation where they did not respond. They are very responsive. They do get back very quickly. That is another very nice thing. It is not like Microsoft where things go into a queue and disappear for weeks at a time or a week at a time. They are also knowledgeable.

Positive

The initial setup was very easy. The documentation was good. I am a stickler, so rather than giving Zerto full rights, I went through the vCenter and allowed just the rights that were specified by the documentation. Those have always been correct, and I have not had an issue. 

The actual implementation of the software went smoothly, bringing everything in. I remember upgrading it. We had a major revision from Windows to the Linux appliance, which was not a full redo, but it was a pretty major changeover. Things are done differently there, and documentation for everything, except authentication, worked very well, and we have had no issues. 

It does not require much maintenance from our end. We mainly need to take care of upgrading and verifying any issues. The software itself runs fine. Every once in a while, I may have too many servers on the same host causing an issue and overloading the VRA. I just separate things.

Overall, I would rate Zerto a ten out of ten. The software has been awesome. It has made my life easier and my sleeping at night better.

My main use case for HPE Zerto Software is to grab big data from our remote locations. In my daily work, the agents from the remote locations are uploading the data, and with HPE Zerto Software, we are receiving this data in packets available to our main head office, especially since we have limited internet connections availability on our remote locations.

We are very happy with HPE Zerto Software, and most importantly, we have a 0% loss in data, which is the great thing we have seen in HPE Zerto Software.

The best features HPE Zerto Software offers for us in our use case are its ability to downsize the data and signatures into multiple packets and send it to the head office due to our limited availability of internet.

This feature of downsizing data and sending it in multiple packets does not impact our workflow because the most important thing is to have data properly available at the head office from a remote location.

The impact of HPE Zerto Software on our organization has been positive, as we have had no issues getting our data from the remote locations, ensuring data availability is always on our location, making our system work very easily with routine jobs ongoing.

Since implementing HPE Zerto Software, we have seen a time save, especially since our main concern was having that data from the remote locations, and there has been no downtime, with everything going smoothly for almost four years now.

HPE Zerto Software can be improved. We are happy until now, and obviously, we are not looking for any new features, but we are sure that if new features were added to the software, they would obviously be helpful for us.

I have been using HPE Zerto Software for almost four years now.

HPE Zerto Software is stable in my experience.

The scalability of HPE Zerto Software is nice, as it is scalable due to our many new locations coming into our system.

The customer support for HPE Zerto Software is great.

I have seen a return on investment with HPE Zerto Software, as it has saved us a lot of time and money, and the new system and features help our employees learn about new technologies.

My experience with pricing, setup cost, and licensing was good, but hopefully, Zerto will do something with the pricing and the license.

Before choosing HPE Zerto Software, we did not evaluate any other options; we went with HPE Zerto Software directly.

I would advise others looking into using HPE Zerto Software to consider it because of the stability and cost savings. I have provided a review rating of 10 for this product.

We use Zerto for disaster recovery automation for our most critical, highest priority, and time-sensitive failovers.

I understand that Zerto can enable disaster recovery in the cloud rather than in a physical data center, but that's not the use case that we have here.

We primarily use Zerto as a disaster recovery product, but we haven't had a disaster. It hasn't allowed us to minimize downtime. However, it helped us avoid the need for downtime during testing scenarios. 

Zerto helps to protect virtual machines in our environment, and that is our primary use case. Zerto provides the most aggressive RPO in the industry, and it really is one of the only products that can give you near real-time recovery.

We use VMware as a hypervisor platform to run all of our virtual workloads. Zerto is the replication service that I use to automate the failovers between my environments without having to have expertise in bringing application replication up, like a SQL cluster would require or an Exchange cluster would require, because the entire VM comes over. It helps us to reduce our overall VM footprint because we don't have to run resources in two different data centers. We can just shift them between the two using Zerto.

The ability to test a failover non-disruptively with Zerto is valuable, as it doesn't create any downtime for the business.

Near-synchronous replication works effectively, and it's important for our databases because that's going to give us the least amount of data loss on the failover.

I run a very dense VM-to-host ratio in my environment. Whenever maintenance is being performed on a host, all the VMs on that host have to be powered down and/or moved off to complete that maintenance cycle. It is frustrating when the protection of VMs doesn't get relocated to another host before the replication appliance powers down. It sometimes works great, but if the host has a lot of VMs on it, there may not always be enough time to relocate all of the VMs from a protection group standpoint to other hosts before the replication appliance that Zerto uses to manage that powers itself down. In such a case, you are breaking replication for the duration of that maintenance, and that can cause some support issues when you bring it back online, where you have to go in and manually recover it. I know they added improvements over the years. It's not as bad as it used to be, but at times, I still end up breaking replication when I do maintenance on my hosts.

I've been using Zerto in my career for about six years.

I've never had any stability issues with Zerto, as the management console has always been reliable, though there are occasional web timeouts. You just have to refresh your browser session to log back in if there's a stale browser window open or something like that, but it has always been easy to log in. I never had to open a support case to use the product. It has been more along the lines of a configuration change or replication. It is very reliable.

Zerto is quite scalable, as they added functionality where if you need to attach more disks and storage, it spins up additional replication appliances automatically. It doesn't require anything from the user to manage those. It happens automatically. I've been able to scale up as needed, with hundreds of VMs without any issues.

I've contacted Zerto's technical support. I've always had a good support experience with Zerto. The engineers are knowledgeable and respond quickly. When I open a ticket, I usually get a call within an hour or two. It's definitely good and better than other vendors that I've worked with.

I was previously using the VMware Site Recovery Manager, but it was very difficult to keep it functioning. We could not rely on that kind of uncertainty for a disaster recovery product. We needed something that's just going to work and not require a lot of assistance to keep it running, whether it's compatibility or upgrades. We needed something that was going to run when needed. Zerto is very reliable. It has definitely been a very stable product for me.

Zerto is the fastest among the solutions I have used. It usually takes less than five minutes to have a full recovery of the VM.

The initial setup with Zerto was easy. I did a proof of concept and got it running within the same day. Deploying it into production was again a very quick experience. The time required depends on how much of the initial configuration you want to do for the VMs you want to protect.

It was just me handling the setup and implementation of Zerto.

I ballpark Zerto's pricing at about $1,000 per VM, which I find fair for what it does, but the cost of entry was tough initially due to the minimum number needed to start. I really needed to prove to the business that it was worth the investment. We started with 15 VMs so that I could show the product does what it needs to do, but ultimately, we needed to protect all of our SQL workloads, so we quickly scaled up from there. 

It's cost-prohibitive for non-critical workloads, so we wouldn't put development servers or any non-business-critical systems in there because we wouldn't need the aggressive RPO and RTO that Zerto gives us for those types of workloads. I accomplished those failovers through other replication technologies.

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

We use Zerto as a disaster recovery as a service which allows us to bring up our entire network infrastructure and all of our critical resources into the Zerto cloud.

The near-synchronous replication feature is very important to us. In the event of a total disaster, we would be able to maintain our presence in the cloud where all of our critical infrastructure will be moved from our on-premises to the cloud.

The RTOs and RPOs are both extremely good; we are talking about minutes versus hours and days to practically have a restore done. It is really helpful for us that we know exactly what the RPO times are, and all of those features allow us to do this.

Zerto has had an impact on our IT resiliency strategy. We are a small company; I am basically the CTO, the CSO, and I do desktop stuff. Having this very easy interface and reduced time to do things allows me to focus on other things that I need to focus on. It has me more at ease knowing that it will work the way it is supposed to, and if I need it, it is going to be there.

Zerto helped to reduce downtime to minutes. We have 90% less recovery times. I can go in there and see exactly what those times are to completely spin up the infrastructure.

I appreciate most that we can do quick failover tests without actually going to live failover, which is very helpful because we have to do SOC audits, and they want to see that we do test this. It is extremely easy to test to show whether or not these things boot up in a test environment, which they do.

Zerto is easy to use. There is a dashboard we log in to, and it shows us everything we need in one dashboard.

There can be a bit more logging. It seems a bit harder to find logs for test restores and all that. If they had a way to email the results of a test restore, that would be excellent.

We have been using Zerto for a good two years.

It is very stable.

Scalability is good. We have to pay for more scalability, and we would have to reach out to them if we were to scale up or scale down.

It was good. It took a little bit longer than I would have thought, but they were able to resolve my problem pretty quickly.

Neutral

We used Unitrends for our disaster recovery, as well as our file backups, but mostly for disaster recovery.

Zerto is 100% above and beyond that. Unitrends was very clunky. It was hard to find stuff, hard to navigate, and extremely hard to use.

It was fairly easy. They sent some documentation, and I worked with the deployment team. It took a little bit; there was a learning curve since this is something I have never used before, but they did help with the initial setup and questions I had.

It was just me.

Zerto has reduced our organization's DR testing. Before, it was a huge cost. It was several thousand dollars to do a DR test, whereas now, I click a button.

Pricing is kind of expensive, but for what we get, it is probably worth it. I know they just had a huge price increase due to the VMware stuff getting expensive, which added about a thousand dollars a month to our bill.

I would absolutely recommend Zerto. If you need a good DR solution, I would say go with Zerto. There are a lot of other options that are cheaper, but you are not going to get the functionality that we have.

I would rate Zerto a 10 out of 10.

I use Zerto for replications for my DR site.

It allows us to have effective backup and recovery.

It hasn't helped anything directly, however, it does give us peace of mind to have a backup we can rely on.

The ease of use, ease of setup, and the dashboard, which is quite user-friendly, are valuable features. Zerto is very impressive and much more resilient. It's very easy to learn. Within a day a user can get up to speed.

It makes us more resilient overall.

The near-synchronous replication is impressive. We have around seven-second RPO times. Our RPO used to be 24 hours. It's drastically reduced RPO.

We have our own data center that we replicate to, however, we're actually in the process of changing that to replicate to a cloud environment.

We've reduced downtime by 90%.

We've been able to reduce DR testing time by 75%.

The speed of recovery is 90% faster.

Zerto works great. The pricing could always be lower.

I have been using Zerto for probably about seven years.

The solution is very stable. I'd rate it nine out of ten.

I'd rate scalability nine out of ten.

I use Veeam for backup and replication. With Veeam, I only had the 24-hour replications.

The initial setup is straightforward.

Implementation probably took just a couple of hours. We had two users involved in the setup, and we have it set up in two locations. There are two people who work directly with the solution. There is a bit of maintenance in terms of updating. They are pretty easy and quick.

I haven't saved any costs since I haven't had a disaster.

The setup is somewhat expensive. I'd rate the pricing seven out of ten.

It's way better than anything else on the market. I'd rate the solution nine out of ten.

I would rate the solution to other users. It works very well.
