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."
"Testing failover capabilities."
"VMware SRM's most valuable features are its convenience and its use of stretched clusters."
"The replication is a key feature."
"The most valuable feature of the solution is the automatic recovery of the virtual machine if it goes down."
"It made the DR process a lot faster and easier for recovery after we were familiar with the product operation."
"The solution is strong when it comes to protection and analytics, with the latter being added later on."
"This SRM solution can improve your footprint within a data center."
"If we had to deal with a ransomware event, Zerto would be one of the first things I would use, because it is going to be the fastest to restore data to a certain point. If there were a fire in our building, Zerto would be a big thing too, because we would shut down everything that's in our building. In most cases, Zerto is definitely one of the front lines. It's definitely going to be one of our prevalent DRBC layers of protection."
"Zerto helped our organization meet compliance requirements by ensuring data protection and recovery strategies align with our regulatory standards."
"The real-time replication of data is the most valuable feature. It is a vast improvement in scheduled daily backups. Real-time data is streamed to the offsite data center, which allows us to restore our mission-critical applications up to 10 seconds from when the last changes were made in our system. If we enter a sales order or enter any kind of information in our ERP application it is replicated within 10 seconds to the offsite location."
"It is convenient to use because the API allows for seamless integration when performing our day-to-day operations."
"The initial setup was very straightforward and easy. We were able to start replication within minutes of the initial setup."
"We have had many instances where VMs were corrupted by an application owner, where they were installing something and did not create a snapshot in VMware for it. Instead of tapping into our backups, with just two clicks, we were able to restore the VM back to its original state. It helps a lot in the day-to-day running of our business."
"Zerto is an excellent solution for cloud-based environments, but for DIY clients who have another site to recover their systems it also works well."
"We've never had any major headaches with the virtual-protection groups. They seem to work exactly as they should. If there's ever an issue with replication, we know right away, so it's all been very reliable."
"I would like to see better integration with other storage solutions. I would hope to see that within the next two or three years."
"The primary site lacks adequate equipment, such as power backup and cooling, which can lead to downtime during issues like power outages or overheating."
"Technical support can take some time to respond."
"Sometimes it can cause a bit of downtime during switchovers."
"The biggest issue for us is that this product does not have any demo for customers."
"The administration guides can be complicated and difficult to use, so it would be helpful if it was made easier."
"We have had an issue when some customers have traditional designs and sites. For example, on one another site, they are using hyper-converged, using VMware, or Nutanix. We have a problem with the synchronization between the storage for site to site. This is the main issue. We are adding some other tools to support the synchronization to allow the movement of the workload from site to site easily."
"This product is not appropriate for those moving to a broader cloud footprint."
"The replication layer can probably be improved."
"Analytics has a 90-day window, where it keeps data. It would be nice to have on-prem storage instead of cloud storage for that so we can keep the data for longer. Unless you discover the problem within three months, you don't know that you need the data. Then, it is gone by the time you realize there is an issue."
"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."
"It would be nice if we were able to purchase single licenses for Zerto. As it is now, scaling requires that we purchase a multi-pack."
"There are a lot of features that it has that we don't use since we are on prem."
"We have had issues with licensing, where the license we've been given by Zerto support doesn't include VSS replication, which was a pain at the time."
"There are certain things about the user interface that could be a little bit more user-friendly."
"You can create a VPG and put anywhere from one to 17 servers in that group. We build them one by one. If something changes in VMware, it would be nice to be able to go in and change that VPG, having it update without messing up. When you change them now, it only applies to the copies from the points when you changed it. I wish it would purge that older data from the past. Right now, we have to build a new VPG, which is not a big deal as it is just a few screens."
