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.
"VMware SRM is very effective between two sites with identical twin storage, you can have synchronization between the two sites."
"It's very reliable. The solution is stable."
"The installation and initial setup are straightforward."
"VMware is one of the best products in the industry when it comes to virtualization."
"The most valuable features are the disaster recovery and testing."
"The most valuable feature of the solution is that you can independently run the disaster recovery without disturbing the production instances."
"My impression is that the initial setup process is relatively straightforward."
"I like how VMware SRM is able to automate and orchestrate disaster recovery."
"The RTO and RPO are unparalleled. In the event you do have an issue, you can be back up and running (depending on the size of your infrastructure) within minutes. Your RTO can be 15 minutes and data loss be five minutes. I don't think that's matched by anybody else in the field."
"Zerto's support for different hypervisors is a valuable feature because we have a mixed bag. We have VMware and we have Hyper-V. For us, that was extremely critical when we made the decision. We wanted a single tool that is able to replicate all our virtual servers. At this point, I think the only tool on the market that can do that on-premise is Zerto."
"Zerto is scalable."
"Zerto is low maintenance, so I can set it and forget it. It has a great process and an excellent solution."
"In our DR testing, Zerto allows us to go work on other things while it takes care of everything. That's valuable because we know that we can still hit all of our SLAs in a real disaster."
"The most valuable for us and for my company is that we are replicating most of our production customers to the DR site, and we can do testing whenever we want."
"The most valuable features of this solution is the ease of use. In the event of a disaster, you don't need a technical person to actually run the software. You can bring anybody in, with the right instructions and credentials, and they can run the solution."
"Zerto is easy to use and the interface is very intuitive."
"The primary site lacks adequate equipment, such as power backup and cooling, which can lead to downtime during issues like power outages or overheating."
"The technical support is not quick enough to respond when a user tries to contact them."
"Technical support can take some time to respond."
"The two vCenters have to be synchronized, which sometimes gives us problems because Keberos does not tolerate more than five minutes in time difference."
"If you have a failover case, you need to work on it manually. It would be helpful if this could be automated. It would simplify things."
"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."
"The solution must provide better integration with third-party vendors."
"Flexibility to choose different PITs would be nice."
"The setup process is time-consuming."
"I haven't been a super big fan of the support area. The support could really be better in terms of responsiveness. I've had some issues that took two or three days to get resolved. Once I got to the right person, they were resolved quickly, but it took a while to get to that person."
"We would like the LTR function to be able to retain the past 12 months."
"We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking."
"Their data backup and restore have some ways to go."
"Now, everything is moving to the cloud and many modern app solutions are based on virtualization and cloud, however, for situations where Unix platforms are used, we'd like them to be able to support that."
"The email alerts can be excessive, so better control over frequency or resolution may be a worthwhile improvement."
"There are still some pieces in testing that aren't automated. There are still some built-in scripts or workflows I wish Zerto would do out-of-the-box, versus having to PowerShell or have a vendor create it, or create it myself."
