We performed a comparison between VMware SRM (Site Recovery Manager) and Zerto based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Zerto wins out in this competition. Its consistent sub-second response for RTO and RPO makes it one of the most responsive and fastest in the marketplace today. Users are able to easily run tests and change scenarios without any effect on an organization's production.
"The solution is simple to use and has effective automation."
"The most valuable feature of the solution is that you can independently run the disaster recovery without disturbing the production instances."
"The most valuable feature is disaster recovery testing."
"The replication is the solution's most valuable feature. If we have some issues on the VM in the main site we can migrate it to another site automatically."
"It has a good and effective user interface."
"The product is evolving and the vendor is committed to change."
"The stability of SRM has been excellent. It gets a nine-out-of-ten."
"The solution is scalable."
"The main purpose of this tool is to allow failover between different data centers and different locations. When one site is unavailable, we can start the failover activity and perform the failover task. When a primary location is unavailable, or there is some hardware or logical issue at the primary location, it allows us to resolve the problem. We are able to start services at safe locations. We handle the disaster recovery process, and this is the main function for which we are using it all the time."
"From a management perspective, one of the biggest benefits is to see the excitement of your engineers having a tool that truly enables them, really making their lives easier. That is something that I love. When we came out of the PoC, their eyes were just wide with excitement of what was possible now."
"Some of the most valuable features are the synchronous replication and migration with RDMs. I really like the conversion of RDM VMs for migration."
"Managing the system is easy and reliable, you can choose any VM you want to replicate to your DR Site in Combination with other VM's."
"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."
"We use to use VMware replication appliances to attempt to replicate our VMs to remote locations and servers, but Zerto's one-to-many replication options with deduplication have made the process much simpler without having to constantly worry about the versions of each driver."
"Zerto provides our customers with the ability to continue work, even if something happens to their office or data center."
"The live failover tests and point-in-time recovery options have been exceptionally valuable features of Zerto for our organization."
"We have had an issue when some customers have traditional designs and sites. For example, on one another site, they are using hyper-converged, using VMware, or Nutanix. We have a problem with the synchronization between the storage for site to site. This is the main issue. We are adding some other tools to support the synchronization to allow the movement of the workload from site to site easily."
"The solution could improve by removing some of the limitations we have been facing. There could be better integrated."
"In my opinion, the integration with Peer Persistent Storage could be improved."
"The version we are currently using is not the latest and greatest but it has buggy behavior in some browsers."
"An improvement for SRM would be better interface compatibility with other products."
"The solution is on the expensive side."
"VMware SRM's platform agnostics should support on-cloud usage as well."
"We've had configuration issues on occasion. We start to fail over, and then we have to call it off because the configuration is not right, or the data stores aren't configured correctly in the secondary data center. Oftentimes, it is just the experience level of the team, and we have to bring in the vendor to help and validate our configuration."
"The backup solution needs to be improved. From our perspective, Veeam and Zerto were competing products. They both do very unique things that they're very good at. For instance, Veeam can do replication well. However, it's really a backup product."
"It is expensive."
"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,."
"Not all of the knowledge required for implementing Zerto is available in their online documentation for non-partners."
"The reporting could be improved in terms of the reports that you can show to auditors to prove that you have done the testing. I provide the reports that it generates now but, it would be great if, at the end of a DR test, it would generate a report of everything that Zerto did."
"The technical support is hit or miss."
"This solution could be improved if it met all the requirements that we look for including supporting multiple operating systems. We would prefer to use one solution for DR and backup."
"There should be an automatic installation in a cluster. When I add a virtual client or ESX source to the cluster, it should automatically install that. There should be automatic installation. Currently, I have to do that manually."
