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.
"Its capability to schedule, write and configure the recovery and scheduled steps, such that you don't have to come in and start manually trying to recover the entire machine. You just push a button to recover the VMware and everything is done."
"The most valuable feature of the solution is that you can independently run the disaster recovery without disturbing the production instances."
"In terms of resiliency, the most valuable aspect of SRM has been its effectiveness."
"The product is evolving and the vendor is committed to change."
"VMware SRM's most valuable features are its convenience and its use of stretched clusters."
"If you want to do failover, it works without any problem."
"The most valuable feature is the simplicity of operations."
"VMware is one of the best products in the industry when it comes to virtualization."
"Journaling allows us to leverage Zerto's journal for sub-minute recoveries, instead of having to wait for the storage array to replicate."
"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."
"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."
"Since we are at a bank, there are certain protocols in place where we need to have RPO and RTO times of two hours or less. Zerto does a great job of setting those times and alerting us if those can't be met. We have our help desk actively monitoring that. It is extremely helpful that Zerto lists what is falling out of compliance in regards to RPO and RTO. It has been great in that regard."
"We had a disaster recovery four or five years ago. I can't remember what happened, but I believe something crashed in our data center, like a power outage. We did a failover of our network using Zerto from production to disaster recovery. We successfully completed the failover process in three or four hours without issue. The data was current, and the application owners could access their data and continue working while the issue was resolved."
"We are in the process of switching over our production data center and Zerto has been a true time-saver that has cost us zero downtime."
"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."
"The pricing and licensing are excellent. It's very straightforward."
"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."
"You need a lot of knowledge to work with the interface because it is not really easy to use, and it would be great if the dashboard were simplified."
"There is room for improvement in the automation and orchestration aspects of this solution."
"Technical support can take some time to respond."
"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 user experience could be more friendly."
"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 technical support is not very good and needs to make an effort to improve."
"Maybe the reporting for the failover test could be a little better."
"If I had to pick anything, it would be the documentation for upgrades. They need to make it easier for users to do upgrades without having to contact support, by providing better documentation for that."
"The only complaint is that if I remove a host from a cluster, it does not like that. If I move and put the host in maintenance mode to fix it, and vRA is down, Zerto does not like it. Zerto should figure out that this host has an issue and it went down. Zerto should then let me upload that vRA information to another vRA."
"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."
"The problem with the backup product is that it's not very mature and you really need a specific use case to be able to use it effectively. It's hard to explain to our customers, especially our large customers, that the use case is so limited."
"The documentation needs improvement in terms of the setup, getting enough detail, and getting that up to speed."
"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."
"There's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for. With the orchestration part of the failover, with our DR and our primary sites, the IP addresses are almost identical. The only difference is one octet. With SRM, we could say during a failover change. With Zerto, we keep hearing that it's coming, but we haven't received it yet. It's a feature that would be very beneficial. It would reduce the time a little bit more."
