Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"The solution is strong when it comes to protection and analytics, with the latter being added later on.""We find the back up feature of this solution to be particularly valuable.""The replication is a key feature.""It has a good and effective user interface.""VMware SRM is a very nice tool for disaster recovery for virtual environments.""The most valuable feature of the solution is that you can independently run the disaster recovery without disturbing the production instances.""VMware is one of the best products in the industry when it comes to virtualization.""The most valuable feature of VMware SRM is its integration with the VMware platform."

More VMware SRM Pros →

"We can failover to an isolated environment and validate the application without impacting the production environment. We can do more testing in a non-impactful way...""We've seen a massive benefit from using Zerto in terms of time savings and consistency. You see a consistent outcome every time you do the conversions. We're moving from one platform to another, but the payloads in what we're moving are different. We see consistent delivery.""Zerto has improved our restoration time and made it easier to test software upgrades. It has simplified tasks like decommissioning a site and replicating virtual machines from one location to another.""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.""It gives us a seamless, performant data center migration. When we were migrating between physical data centers, we did what normally would have been a 72-hour job in about 18 hours. A large part of that was thanks to Zerto being able to rate limit and throttle how much data was being sent or transfers were happening. Being able to script around it and create governors was important. We didn't have that previously. That is one big use case that has saved an immense amount of time and effort.""With Zerto, all you have to do is deploy the executable and start setting things up. So, it was very easy.""We are moving to a new data center. There are several VMs that we have to move over there that have RDM disks or SQL clusters. Those are the hardest things to move at this point in time, but now that I have the setup and it is ready to go, all we have to do is just flip the switch and get everything over where they are supposed to be. It is going to be a lifesaver for me. It will save me a whole lot of time in putting things back together.""I like that Zerto is easy to move and that there is no effect on the user. That is, the user doesn't even know it. We're in the healthcare industry and work for a hospital. We can set up a server in no time whatsoever. It's easy for us to schedule the time because it takes only about one minute."

More Zerto Pros →

"VMware SRM lacks certain functions that other platforms have, such as better prioritization of allocation of resources and Boot profiles.""Technical support needs improvement, they are not very responsive.""The initial setup of VMware SRM isn't straightforward because many customizations are required since it helps in the recovery of your IT environment.""The solution could improve by removing some of the limitations we have been facing. There could be better integrated.""It would be good if this solution could integrate configuration management software such as Chef Infra.""The administration guides can be complicated and difficult to use, so it would be helpful if it was made easier.""In my opinion, the integration with Peer Persistent Storage could be improved.""Lacks stability and as a result requires continuous monitoring."

More VMware SRM Cons →

"I don't feel like we're a big enough customer to warrant being called every week or every month but it would be good to get a little bit more contact with a salesperson or engineer group.""More user support would be best for me because I'm not in the product all the time. So, having strong support is probably the most important decision on any products that we buy.""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.""The only thing I really don't like about Zerto is that the ZVM has to be a Windows server. I can spin up any OBA template whenever I want to, but if it has an OS that's tied to it, then I have to involve the OS team from my company. That drives me crazy.""The time between releases is too long. Zerto doesn't seem to really keep up with the products with which they need to be compatible. For instance, the 9.5 updates 3 took about 90 days to come out after the latest version of vCenter 7.0 update 3 was released.""It would be nice if Zerto offered OVFs, which are custom-built VMs that you can install on your virtualized environment. At the moment, I have the Zerto sitting on two custom-built Windows servers, which creates a lot of overhead. I'm waiting for them to create an OVF file, which is a built and hardened version of their Zerto server that I can just install wherever with a couple of mouse clicks.""I don't have any input for improvement or a critical feature request at this moment. If anything, a lower price is always better.""Even though Zerto is for disaster recovery, it would be nice if it can also make backups."

Pricing and Cost Advice
  • "There is an annual license to use this solution."
  • "The price of VMware SRM depends on how many VMs the customer has to move. There is a difference between the standard and enterprise license. I'm presenting the standard license to my customers because the total of VMs is not more than 50. The customer needs only the standard license and the cost is very effective for him."
  • "The price could be lower, in general. My clients pay for an annual license."
  • "VMware SRM is quite expensive."
  • "SRM is reasonably priced for the functionality it provides."
  • "The level of licensing required for this solution is dependent on the server instances in use."
  • "We have a standard enterprise license for the solution."
  • "I rate the solution's pricing a six on a scale of one to ten, where one is the lowest and ten is the most expensive."
  • More VMware SRM Pricing and Cost Advice →

  • "Licensing Zerto was very simple. They had a product that fit our size and scale. It made it really easy to choose."
  • "It was a little bit expensive. It took a long time for us to get DR for our workstations. It's one thing when you have 15 servers, but when we needed to bring on almost another 200 users, and each was the same price as the servers, it was too expensive. But Zerto worked with us and gave us a solution that was pretty decent in terms of price."
  • "Obviously, I wish it were cheaper and more affordable. But I get what I pay for, so I can't complain."
  • "Everyone knows Zerto is a little on the expensive side, but what else is there on the market that does the same thing?"
  • "The only negative part that I have seen so far has been the cost. It is kind of pricey, but you get what you pay for. Zerto is a lot faster than other solutions and you get enhanced performance."
  • "It works very well as a backup and recovery solution, with frequent recovery points. It's very good. But it's too pricey for us to use it as a backup solution for all of our clients. Not every customer needs recovery points every five seconds."
  • "Zerto is fairly expensive, but worth it."
  • "In general, it's pretty fair because it is software. In our case, we built our own colo. So, the cost of the colo was very expensive, and that's where a lot of the equipment is. The same thing is there if we were going to spin up in the cloud, but as a solution, in general, it's pretty fair for what you get out of it and how it works. It's not cheap, but at the same time, you get what you pay for, and it's definitely worth the cost. You just have to understand that the cost of the software alone is not the total cost of the project of doing ransomware protection or disaster recovery. It's a piece of the pie, not the entire pie."

    Reviews from Real Users

    Below are reviews from PeerSpot users who are currently using the solution:

    PeerSpot user Eslam E., Senior Solution Architect at ICT Misr, explains his experience using the solution and says that "VMware SRM is very effective between two sites with identical twin storage, you can have synchronization between the two sites."

    A founder at a comms service provider commented on the solution's efficiency, noting, "If you want to do failover, it works without any problem."

    Reviewer Rakesh-P., who is a consultant at Ashtech Infotech (India) Pvt.Ltd., mentions why he finds VMware SRM to be a good product, commenting that “The most valuable feature is disaster recovery testing. The reports are very good.”

    Ahmed F., a consultant at Daniyals Inc, says that the solution doesn’t require a lot of resources and that "The UI is very user-friendly and testing is easy."

    Zerto, a Hewlett Packard Enterprise company, specializes in data protection and empowers customers to run a business by simplifying the protection, disaster recovery, and mobility of on-premises and cloud applications. Zerto uses advanced hybrid cloud IT technologies to recover and protect business-critical applications in on-premises and cloud environments, enabling them to deliver continuous service without compromising security. Zerto’s foundation is based on continual data protection (CDP) technology. Users can benefit from a single, unified, and automated recovery and data management experience across all virtualized or container-based workloads.

    Zerto's native clustering technology creates a resilient, fault-tolerant system that automates recovery of critical virtual machines while supporting software updates, new OS releases, and upgrades. With native clustering, a creation, migration, or deletion of a virtual machine is automatically replicated to all nodes in the cluster. This creates an automated failover and availability solution with the features of high-end dedicated servers running at a fraction of the cost.

    Zerto Features

    Zerto has many valuable key features. Some of the most useful ones include:

    • Continuous data security
      • Continuous replication
      • The industry's lowest RPOs and fastest RTOs
      • App and database protection and recovery on a granular level
    • Agility across hybrid and multi-cloud
      • Protection between clouds
      • Simple on-premises to cloud migration
      • User-friendly native cloud services
    • Simple to scale
      • Automation and orchestration are built-in
      • Cross-platform, multi-site analytics
      • Unified experience regardless of cloud
    • Software-based
      • Hardware, hypervisor, and cloud are all independent
      • No physical appliances
      • Future-proof

    Zerto Benefits

    • Robust disaster recovery: Continuous data protection enables recovery of entire clusters, multi-VM applications, or even a single server with the lowest RPOs and fastest RTOs. Zerto allows users to safeguard, manage, and recover all of their key digital assets, whether they’re recovering to a secondary location, the public cloud, or a managed service provider.
    • Constant backup: Instead of making backups every 12 or 24 hours, Zerto creates backups every 5-15 seconds. Zerto backup has no impact on production and eliminates the burden of micromanaging backup windows by using CDP instead of snapshots. Its backup provides immediate recovery of data, folders, or virtual machines (VMs) that are only seconds behind the original, which is a simple approach to completely avoid ransomware or erase inadvertent deletions.
    • Strong long-term retention: Send data to the cloud or a purpose-built storage appliance of your choice for months or years of retention. These long-term copies can be made from local backups or DR replicas, and they can be kept wherever is most convenient for your company. Its powerful indexing and search makes discovering and restoring data simple. For data you want to maintain but only use infrequently, use cost-effective cloud tiering to shift LTR copies from hot to cold to deep-freeze storage.

    Reviews from Real Users

    Zerto stands out among its competitors for a number of reasons. Two major ones are its disaster recovery abilities and its ease of use. PeerSpot users take note of the advantages of these features in their reviews:

    Justin C., Director of IT at Arnott Inc. writes of the solution, “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… It's definitely going to be one of our prevalent DRBC layers of protection."

    Brad W., Vice President of Information Technology at a financial services firm, notes, “The file restoration is very helpful. They've improved it over the years to make it a lot more user-friendly and easy to do, which I appreciate. So, we use that quite a bit. The failover process is quite simple and intuitive. Even the configuration and setup are pretty easy to do.”
