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 is the automation, where you press a button and everything fails over seamlessly."
"Virtual Machine Recovery during DR situation, with automation and easy to use menus and options."
"SRM's best feature is automation."
"This SRM solution can improve your footprint within a data center."
"If you want to do failover, it works without any problem."
"The solution runs well in the background, just in case we need it."
"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."
"Its ease of use and scalability are valuable."
"We can use Zerto to help protect our VMs."
"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."
"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"
"The disaster recovery features are the best I've found."
"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."
"We selected Zerto because the RPO is extremely low, so you can get that server back up almost immediately. That was a huge thing. Also, the ability to do failover tests, where you can test your environment, but not have it impact your production environment, was huge."
"Its user interface is excellent, and when it comes to data duplication, Zerto is very fast."
"The interface is not easy to use and can be made more user-friendly."
"We would like the patching management function of this product to be improved."
"SRM may hit some OS issues related to IP changes, but they are usually OS related, especially in the 2008 realm."
"The solution must provide better integration with third-party vendors."
"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."
"In my opinion, the integration with Peer Persistent Storage could be improved."
"The two vCenters have to be synchronized, which sometimes gives us problems because Keberos does not tolerate more than five minutes in time difference."
"I would like to see better integration with other storage solutions. I would hope to see that within the next two or three years."
"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."
"There are quite a few elements in the long-term retention areas that I wish were better. The bio-level recovery indexing of backups is the area I struggle with the most. That's probably because I desire to do tasks that ordinary users wouldn't do with the solution. The standard medium to large customer would probably never ask for anything like I ask for, so I think it's pretty good the way it is. I'm excited to see some of the new improvements coming in the 9.5 version. Some of the streamlines and how the product presents itself for some of the recovery features could be better."
"The replication appliances tend to have issues when they recover from being powered off when a host is in maintenance mode. Sometimes you have to do a manual task where you go in and detach hard disks that are no longer in use, to get the replication appliances to power back on. There are some improvements to be made around the way those recover."
"Zerto could be considered as a backup product but this is not true. So if we could consolidate and use Zerto for disaster recovery as well as everyday backup and restore for situations where we need to recover something, that would be helpful. Anyway, we think that Zerto will win with no competition in the Disaster Recovery process, so we stay focused on this. Now we are testing version 10 which include real-time ransomware detection, a new Cyber Resilience Vault and enhanced cloud capabilities and security: we expect more from these features for superior hybrid cloud security."
"I would like to be able to replicate one to multiple without having to recreate every VPG. That would save us a lot of time. When we add a site or move our DR to a different site, I have to recreate everything from scratch. So, it'd be cool to be able to just repoint an existing VPG to a new site without having to recreate everything."
"I have had problems with vRAs. When I am trying to restart a host, sometimes the vRAs will hang. I would like it if they wouldn't migrate off or shut themselves down, then I have to manually work with it a lot of the time."
"For special situations, there are options within advanced settings. You don't have to dig too far for them, but they're not quite as straightforward."
"Another thing that would help would be a recommender, or some type of tool that says, 'Hey, you're not conforming to best practices.' It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on."
