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.
"It's very reliable. The solution is stable."
"Testing failover capabilities."
"VMware's tech support gets a nine-out-of-ten. They are responsive and get you a useful reply."
"It is a very stable solution...I was involved in VMware SRM's deployment phase two years ago, and it was an easy process."
"The solution is very flexible."
"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."
"Our systems fail over using SRM. So, we do a big bang DR, which is biannual, and we fail over our fairly massive Epic electronic health record (EHR) and our core applications. It takes us about 30 minutes to fail over using SRM, which is pretty good. In most hospitals that have Epic installed, Epic does the audit to make sure that we can fail over if something were to happen. Normally, sites will have a DR solution specific to the EHR, but right now, our pain point is the third-party tier-one clinical applications."
"The solution is scalable."
"Files can also be extracted from the VMDK at the remote site even when the VM is off."
"The live failover tests and point-in-time recovery options have been exceptionally valuable features of Zerto for our organization."
"The replication works really well. We perform multiple tests a month and annual tests for our tier-one and many of our tier-two apps... Migrating systems as a failover rollback or a system move are two of the functions that I like the most."
"The most valuable feature is the ease of upgrades."
"The disaster recovery features are the best I've found."
"Zerto offered a very good front-end GUI for orchestration. The graphic interface was very good."
"It's also very much faster than any other migration or disaster recovery platform we have. I work with virtualization, mostly on VMware, and I must admit that Zerto is even better than VMware Site Recovery Manager. Zerto compresses the data and it works much faster."
"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."
"The version we are currently using is not the latest and greatest but it has buggy behavior in some browsers."
"The product's dashboard is an area of concern where improvements are required."
"The primary site lacks adequate equipment, such as power backup and cooling, which can lead to downtime during issues like power outages or overheating."
"VMware SRM's platform agnostics should support on-cloud usage as well."
"SRM has to be installed on two separate data centers, so both have to be coordinated very well, which becomes complicated when configuring the software for disaster recovery."
"The back sites sometimes are very, very complicated."
"The technical support is not quick enough to respond when a user tries to contact them."
"The configuration process could be improved."
"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."
"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."
"One improvement that could make it easier would be to have an easier way to track journal usage and a little bit more training around journal sizing. I've done all the training and the journal is still a gray area. There is confusion surrounding how it's billed and how we should bill clients. It would be easier if it had billing suggestions or billing best practices for our clients to make sure that we're not leaving money on the table."
"We learned that we got a new account representative supporting our account. I found this out today. Apparently, this is something that they kicked off at the beginning of this year, but there has been a failure in communication in letting us know who is the proper channel for us to reach out to if we need assistance."
"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."
"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."
"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."
"The RPO for our SQL server has room for improvement."
