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."
"The most valuable feature is the integration with our Nutanix environment."
"The solution is simple to use and has effective automation."
"The most valuable feature of the solution is that you can independently run the disaster recovery without disturbing the production instances."
"If you want to do failover, it works without any problem."
"The most valuable feature is disaster recovery testing."
"VMware SRM is a very nice tool for disaster recovery for virtual environments."
"It is easy to implement for my clients."
"Since the log files are continuously transmitted, the granularity of restores is amazing."
"The most valuable features are the single pane of glass and the reduction in time it takes for our systems engineering team to manage the platform."
"For most use cases, the failover time is a handful of minutes, if that. A single user can run the system."
"We can spin up our environment in DR without affecting production, which is probably the biggest feature for us. We have the ability to do passive testing. We can even test scenarios, such as installing software or changing software. We can make modifications without affecting our production environment. So, the test functionality of being able to test the failover solution and being able to bring up our virtual machines in a test mode is the biggest benefit."
"Zerto offered us massive time saving and consistency. We have a consistent outcome every time we complete conversions."
"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."
"The initial setup was very straightforward and easy. We were able to start replication within minutes of the initial setup."
"There is room for improvement in the automation and orchestration aspects of this solution."
"Sometimes it can cause a bit of downtime during switchovers."
"The solution could improve by removing some of the limitations we have been facing. There could be better integrated."
"The solution must provide better integration with third-party vendors."
"You cannot use VMware SRM in conjunction with storage replication software."
"SRM may hit some OS issues related to IP changes, but they are usually OS related, especially in the 2008 realm."
"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."
"We would like the patching management function of this product to be improved."
"Some of the ability to automate selections and automate VPG creations could be better."
"It would also be nice if they could find a way to make it where one VM does not impact the entire journal history of the VPG."
"Increased granularity in how long to keep the journal would be nice."
"The VPG model causes us a bit of concern. We are considering using Zerto to replace Site Recovery Manager. Site Recovery Manager is very easy when we have entire data scores being replicated. We don't have to make any decisions when it comes to groupings. It is all covered. If we move to Zerto, which we are considering, we will have to work much closer with the applications teams to develop the VPG configuration and determine how the VMs will be grouped. It will be a lot more overhead for us to go that route."
"It would be beneficial if Zerto also offered integration with other cloud management platforms, such as VMware Aria Automation."
"This solution could be improved if it met all the requirements that we look for including supporting multiple operating systems. We would prefer to use one solution for DR and backup."
"They could improve their online documentation."
"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."
