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 replicates the VM from one site to another, and it helps us orchestrate the powering of VMs and DR when the DC goes down."
"It is a stable solution...The solution's technical support is excellent."
"The thing I like the most about SMR is the reduced cost of management."
"VMware SRM's most valuable features are its convenience and its use of stretched clusters."
"The stability of SRM has been excellent. It gets a nine-out-of-ten."
"The solution is very flexible."
"We find the back up feature of this solution to be particularly valuable."
"The solution is consistent."
"From a management perspective, one of the biggest benefits is to see the excitement of your engineers having a tool that truly enables them, really making their lives easier. That is something that I love. When we came out of the PoC, their eyes were just wide with excitement of what was possible now."
"The instant recovery at DR locations is the most valuable feature. We're required to do periodic DR tests of critical databases, including Oracle and Microsoft SQL. We have recovery point objectives set for specific databases and we need to be able to achieve them. Zerto helps solve that business problem."
"The fact that we are able to test the failover of live systems during regular hours is invaluable to our organization."
"Zerto is very good at providing continuous data protection. For replication purposes, it's definitely better than Veeam. Veeam doesn't do as good a job as Zerto does when it comes to replication. The other alternative would be to just have backups somewhere. But even with backups, you lose a lot of time because you have to set it all up. With Zerto, you failover, you just click a couple of buttons and you run from the other location."
"Zerto's continuous data protection is unmatched. It's phenomenal. It's also very easy to use. The menus are self-explanatory. Once you understand the terminology of the product, what the VPGs (Virtual Protected Groups) are, you're able to pretty much do what you want in the product. It's very easy to use."
"Its ease of use and scalability are valuable."
"The simplicity of use is valuable. It is easy. We just click Failover and do it. It is pretty straightforward. If someone wants to do a test failover, they log in to the console and do a test failover"
"Another big attraction is the near zero RPO. A lot of other products have minutes, half-hour, or an hour RPO. We have proof indicating that Zerto is near zero, or a matter of minutes, as far as the RTO is concerned. So again, that's another attractive offering where you can actually fail something over and bring that back up in a target location in a matter of minutes. Meaning very little data loss as far as recovery time. It's fantastic."
"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 needs to be better stability during heavy capacity in future releases."
"What I think can be improved is the data replication aspect."
"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 back sites sometimes are very, very complicated."
"Timing issues arise due to replication lags in multiple areas. When this happens, we encounter errors."
"In my opinion, the integration with Peer Persistent Storage could be improved."
"The interface is not easy to use and can be made more user-friendly."
"It is expensive."
"I wish Zerto had better file restoration capabilities. We have not been able to use that because of the limitations of Zerto's de-duplication technology."
"We're an NSX-T shop, and if I could get an NSX-T integration where it could manage the networks a little tighter, that would be an improvement."
"It would also be nice if you could update without having to download a new installation file for Zerto Virtual Manager. Within the app, it could prompt you to install and perform the installation from within the application. Generally, it's relatively easy to use, but it gets a little complex when customers have special network requirements and need to customize how long they want the save points to be retained. We need to work with the storage team on the backend to see what makes the most sense for the client."
"The alerting has room for improvement as it is the biggest pain point with the software. It is so bad. It is just general alerting on or off. There are so many emails all the time. You have no control over it, which is terrible. It is the worst part of the entire application. I have voiced this to Zerto hundreds of times for things like feature changes. Apparently, it's coming, but there is nothing concrete as to when you can do it."
"I would like Zerto to add support for VMware's lifecycle manager."
"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 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."
