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 UI is very user-friendly and testing is easy."
"The most valuable feature of VMware SRM is its integration with the VMware platform."
"If you want to do failover, it works without any problem."
"VMware SRM's most valuable features are its convenience and its use of stretched clusters."
"The most valuable feature of the solution is that you can independently run the disaster recovery without disturbing the production instances."
"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."
"VMware is one of the best products in the industry when it comes to virtualization."
"The solution is strong when it comes to protection and analytics, with the latter being added later on."
"The granularity enables us to failover specific workloads instead of an all-or-nothing type of scenario, where you have to move your entire IP block and your data center, or you have to move large chunks of VMs. Those situations also make it prohibitive to test effectively."
"The pricing and licensing are excellent. It's very straightforward."
"Zerto is so easy to use that when I showed it to my manager, he said jokingly, 'Huh. I could use it myself, I don't need you.' Zerto is most elegant."
"The DR - Disaster Recovery - is the main selling point."
"The ease of use is one of the most valuable features when it comes to making changes and configuring. It's very easy to set up and configure. It's a great product."
"There wasn't anything in place that compares to what we're getting from Zerto. Before Zerto, we didn't have a proper disaster recovery program or application in place. We had a simple backup solution where we could back up our data every 24 hours. So we went from that to being able to recover full systems within a matter of minutes. With Zerto, if we do have an event or disaster, we know that we can recover from that much quicker than we were able to before."
"If we had to deal with a ransomware event, Zerto would be one of the first things I would use, because it is going to be the fastest to restore data to a certain point. If there were a fire in our building, Zerto would be a big thing too, because we would shut down everything that's in our building. In most cases, Zerto is definitely one of the front lines. It's definitely going to be one of our prevalent DRBC layers of protection."
"It has enabled DR protection for virtual appliances with minimal administrator time."
"I would like to see better integration with other storage solutions. I would hope to see that within the next two or three years."
"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"
"SRM may hit some OS issues related to IP changes, but they are usually OS related, especially in the 2008 realm."
"Technical support can take some time to respond."
"Lacks stability and as a result requires continuous monitoring."
"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."
"There is room for improvement in the automation and orchestration aspects of this solution."
"The interface is not easy to use and can be made more user-friendly."
"If I have to reboot a virtual machine host, I have issues with Zerto catching up afterward. That's about the only thing I would say needs improvement. Sometimes, when I have to do maintenance, Zerto takes a little bit to catch up. That's understandable."
"The only issue I've ever had is that I wish that Zerto would work more closely with VMware. There have been a few times that Zerto has released an update but it wasn't supported with that version of VMware. I would like them to coordinate their updates with VMware's updates."
"More user support would be best for me because I'm not in the product all the time. So, having strong support is probably the most important decision on any products that we buy."
"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'm not sure if it has throttling, meaning, what's going over the wire and how we can throttle that to reduce the amount of data that's going across the bandwidth. I can't remember if that's something that's in this product. It might be in the more recent version."
"Adding or changing VPGs (Virtual Protection Groups) may require restarting replication."
"Zerto is solid. However, they are working on a cloud workload protection and protecting virtual workloads to more than one site."
"I need to get up to the latest version so I can move my journals to a particular LUN, saving them with a particular storage altogether, rather than with the virtual machine. This is not available until I upgrade, and I need to upgrade all my hypervisors. This would be something that would be nice to have if it could be used on older versions."
