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 is easy to implement for my clients."
"The product is evolving and the vendor is committed to change."
"Testing failover capabilities."
"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."
"The most valuable feature is the automation, where you press a button and everything fails over seamlessly."
"VMware SRM is very effective between two sites with identical twin storage, you can have synchronization between the two sites."
"It eliminates the need for complex compliance requirements, making it a highly effective solution."
"The solution is simple to use and has effective automation."
"The UI is straightforward. It makes it very simple to group our resources and understand that our production workloads are covered because we can set them up as granular or as non-granular as we want."
"It is the backbone of our DR solution for critical databases that hold the data we can't afford to lose. It provided new opportunities to change how we approach disaster recovery."
"Its ability to roll back if the VM or the server that you are recovering does not come up right is also valuable. You have the ability to roll back a few seconds or a few minutes. The rollback feature is great."
"I like the less than one-minute RPO, the ability to IP customize during failovers, and the cloning feature that I can use to clone VMs over at the target location. As part of the automation failover, if we need to change an IP when it fails over to the other data center, Zerto will handle that; there's no need for manual intervention. As far as the cloning, we use that to do quick testing of a VM in the remote data center for lift-and-shift processors."
"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 ease of use is one of the best features. Previously, we were using Site Replication Manager with VMware and it was a little bit cumbersome. With Zerto, we liked the fact that it was hardware-agnostic and we were able to spin it up pretty quickly and get it working."
"RPO time for the copied-off VMs appears to be quite short."
"VMware VM replication over narrow WAN bandwidth."
"There needs to be better stability during heavy capacity in future releases."
"Technical support can take some time to respond."
"Cost is definitely an area where the product could be improved."
"Flexibility to choose different PITs would be nice."
"What I think can be improved is the data replication aspect."
"The technical support is not very good and needs to make an effort to improve."
"We would like the patching management function of this product to be improved."
"The solution currently has a five-minute RPO, meaning if the VM goes down we can lose up to five minutes of data which is a big deal when it relates to database replication."
"The monitoring and alerting functionality need to be improved."
"It works only for a virtual platform, it does not support bare metal."
"Zerto's near-synchronous replication is excellent when it works. I'm trying to be nice to them because I like the product a lot, but we're having a lot of difficulty with it in our environment."
"Its initial setup can be better. It looks easy, but if you do not have things in the right place, it is not as easy as it looks. Some of the instructions were not clear. They were a little bit confusing. For example, while setting up SSH initially, it was a little bit unclear if I needed to use a regular credential or some other credential. This was one of the things that was a little fuzzy, and we had to get somebody else involved to help us out."
"If I were to nitpick, I would say that I wish I had a better account manager. Our sales guy has changed a couple of times. I would like a little more responsiveness from our account manager. I've had a couple of issues where getting in touch with him has been a little difficult, and I end up just going around him and dealing with support and support has handled it right away."
"The documentation needs improvement in terms of the setup, getting enough detail, and getting that up to speed."
"We would like the LTR function to be able to retain the past 12 months."
"Zerto could improve its reporting capabilities."
