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.
"In terms of resiliency, the most valuable aspect of SRM has been its effectiveness."
"This SRM solution can improve your footprint within a data center."
"The product functionality is fairly high-quality."
"I like how VMware SRM is able to automate and orchestrate disaster recovery."
"VMware SRM replicates the VM from one site to another, and it helps us orchestrate the powering of VMs and DR when the DC goes down."
"The most valuable feature of the solution is that you can independently run the disaster recovery without disturbing the production instances."
"VMware SRM is a very nice tool for disaster recovery for virtual environments."
"The replication is a key feature."
"Another advantage is the ease of use. You can click through instead of typing in the code. It's all already scripted down to the network adjustments within the VMs and the timed delays for servers that need to come up in sequence. Overall, it's a good package for us to use. We started using it in about 2018 and haven't looked back."
"The mobile application is very useful as a real-time monitoring, reporting tool. When asked the status of our machine backup and recovery ability, an easy answer is to display the status on the real-time application or browser. The Zerto Analytics tool helps predict future storage needs by tracking trends in space, journal size, and I/O rate. These are reportable statistics making quantifiable tracking easy and accurate. Having a web interface simplifies access by other system administrators."
"If we lost our data center and had to recover it, Zerto would save us a great deal of time. In our testing, we have found that recovering the entire data center would be completed within a day."
"Its ease of use and scalability are valuable."
"RPO time for the copied-off VMs appears to be quite short."
"The most valuable feature is the point in time recovery. This allows us to recover at any point in time, up to a minute or so."
"VMware VM replication over narrow WAN bandwidth."
"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."
"The product's stability could be better."
"The solution is on the expensive side."
"The technical support is not quick enough to respond when a user tries to contact them."
"VMware SRM's platform agnostics should support on-cloud usage as well."
"The price, in general, could be lower."
"There needs to be better stability during heavy capacity in future releases."
"An improvement for SRM would be better interface compatibility with other products."
"In my view, if VMware comes up with an appliance-based solution like vCenter Server (which was also Windows-based), it will be much easier for deployment. I"
"The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that you're only able to replicate one way. Technical support for this product was fantastic, before they were acquired by HP. You're now able to tell that the company is becoming too big, in terms of the support they provide."
"The time between releases is too long. Zerto doesn't seem to really keep up with the products with which they need to be compatible. For instance, the 9.5 updates 3 took about 90 days to come out after the latest version of vCenter 7.0 update 3 was released."
"It would be nice if Zerto offered OVFs, which are custom-built VMs that you can install on your virtualized environment. At the moment, I have the Zerto sitting on two custom-built Windows servers, which creates a lot of overhead. I'm waiting for them to create an OVF file, which is a built and hardened version of their Zerto server that I can just install wherever with a couple of mouse clicks."
"I would like to see improvement on the Zerto Virtual Replication appliances, so that they are a little bit more streamlined as opposed to now where they just span multiple ZVR appliances like there were gremlins... as this thing grows it just spawns unlimited numbers of additional ZVR appliances and you end up with a bunch so that you can't really tell which is which."
"I would like to see better notifications when the sync is off for an extended length of time."
"When I have a technical question, it sometimes takes a while for tech support to respond."
"I had to have my colleague contact technical support because we had an issue where VMs in VMware were getting blocked, and we weren't able to delete them."
"I have had problems with vRAs. When I am trying to restart a host, sometimes the vRAs will hang. I would like it if they wouldn't migrate off or shut themselves down, then I have to manually work with it a lot of the time."
