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 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."
"Virtual Machine Recovery during DR situation, with automation and easy to use menus and options."
"This SRM solution can improve your footprint within a data center."
"It is a stable solution...The solution's technical support is excellent."
"If you want to do failover, it works without any problem."
"I like how VMware SRM is able to automate and orchestrate disaster recovery."
"My impression is that the initial setup process is relatively straightforward."
"The most valuable feature is disaster recovery testing."
"The replication feature where it constantly replicates and sees that data is always in sync is valuable."
"The dashboard was easy and the UI was simple."
"It reduced the backup recovery time of our main backup solution by several hours. It's reduced our time because before we have to build a system and restore the data, we install the application and restore the data that took us at least a good 24 hours to do that. And now it's really minutes for us to recover our backup solution."
"Consistency Groups: If you replicate groups of VMs, then during failover, all of the VMs in groups are failed over to the exact same point in time."
"Using Zerto for the migration was incredibly valuable, enabling us to save tremendous amounts of time."
"A new feature is the One-To-Many VPG allowing a VM to be replicated at up to three different locations, including local."
"The real-time replication of data is the most valuable feature. It is a vast improvement in scheduled daily backups. Real-time data is streamed to the offsite data center, which allows us to restore our mission-critical applications up to 10 seconds from when the last changes were made in our system. If we enter a sales order or enter any kind of information in our ERP application it is replicated within 10 seconds to the offsite location."
"It is pretty easy to use. The interface is intuitive and easy to use. Once you set it up, it just works. So, it is great."
"Lacks stability and as a result requires continuous monitoring."
"VMware SRM lacks certain functions that other platforms have, such as better prioritization of allocation of resources and Boot profiles."
"The biggest issue for us is that this product does not have any demo for customers."
"Technical support can take some time to respond."
"Flexibility to choose different PITs would be nice."
"An improvement for SRM would be better interface compatibility with other products."
"In general, the drawbacks of VMware SRM, where improvements can be made, stem from the fact that it is an expensive and complex product."
"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."
"It would also be nice if they could find a way to make it where one VM does not impact the entire journal history of the VPG."
"Adding or changing VPGs (Virtual Protection Groups) may require restarting replication."
"When building out a VPG and doing the machine types within Azure, they were not coming across correctly. It would say it had a CPU and memory of a specific type, but it was not accurate... It was a bug and they were working on it."
"It would be helpful if the reports can be generated periodically, on a schedule."
"The technical support response needs improvement."
"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."
"We did look at the long-term retention backup feature of Zerto a few years ago, and at that time, it was limited. I can't say what it is right now, but at the time, its functionality was limited in terms of basically where we could save it and how we could save it. Offsite air gapping our backups is important to us to help protect against ransomware, and at the time, it couldn't do that. That would be one area that would be important before we consider using the long-term retention again. I haven't looked at it recently, and they may have addressed this in the meantime, but if not, this would be an area of improvement."
"If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens."
