We compared Nasuni and Zerto across several parameters based on our users' reviews. After reading the collected data, you can find our conclusion below:
Comparison Results: Nasuni is highly regarded for its storage capabilities, simplicity, scalability, and security features. However, it may require additional assistance during setup and could improve in terms of platform support and user-friendliness. Conversely, Zerto receives praise for its continuous data protection, quick recovery, ease of use, and integration with VMware. Its initial setup is straightforward, but some users express the need for enhancements in licensing structure and support. Nasuni prioritizes storage and IT operations, while Zerto specializes in data protection and disaster recovery.
"I particularly like the restore process. Our financial teams make changes to spreadsheets and other files, and we've got teams using Photoshop files. They make mistakes and need to recover files, and we can do that instantly. We also have users who manage to delete folders, and we can bring them back instantly within a few seconds."
"We use Nasuni's continuous file versioning feature and it fully protects us. With the ability to version files and have continuous recovery, it helps in terms of resiliency. If we have an incident then we would be able to easily recover from it by using the technology."
"The global file locking feature is valuable. The ability to quickly deploy new sites is also valuable."
"Nasuni is tremendously easy to manage. It eliminates many of the administrative challenges associated with physical hardware storage, and you don't need to worry about any hardware failure or products reaching the end of their lives."
"Another helpful feature, in addition to restoring a file that was deleted within 24 to 48 hours, is that we have the ability to restore a file or a folder that was deleted, going all the way back to the inception of that file or folder. That means we actually have unlimited backups to the inception point of data with Nasuni."
"The snapshot functionality and the unified file system are definitely the most valuable features for us. The UFS allows everybody across the organization to see the exact same data at the same time, instead of having different file servers with different structures on them, and that's mission-critical. We have different branches throughout our organization that have to act on that data."
"Nasuni has the capability of taking a snapshot every five minutes. If a user has accidentally deleted their data, we can recover it from the snapshot and provide the latest data to the user. It's a really great feature, one that is not provided by other vendors."
"We have less downtime and fewer trouble tickets from users who cannot access their shared files. Nasuni has reduced the friction and noise associated with file management because the devices are more reliable."
"Zerto is fast to restore our mission-critical servers when needed."
"We relocated all our virtual machines from Belgium to Budapest, Hungary. I am not sure how we would have done it without Zerto, because we were able to keep the data in sync. We would have needed to have a lot more expensive storage products online at the time that could have kept that replication. From what I have seen from other methods, that would have required a much higher amount of bandwidth as well, then the cost would have been extreme. The mechanisms available to us with a storage space replication would have been more labor-intensive and prone to error. It was much easier and more successful with Zerto than other ways at our disposal."
"Another big attraction is the near zero RPO. A lot of other products have minutes, half-hour, or an hour RPO. We have proof indicating that Zerto is near zero, or a matter of minutes, as far as the RTO is concerned. So again, that's another attractive offering where you can actually fail something over and bring that back up in a target location in a matter of minutes. Meaning very little data loss as far as recovery time. It's fantastic."
"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."
"The ability to fully test your entire environment without actually performing a failover is invaluable."
"When we use our VMware environment, sometimes the HP hardware is not compatible, and we start to lose data. I like that we can restore our whole application and public-facing system through Zerto."
"Its automation and the ability to replicate and keep an RTO of just seconds is valuable. It is all automatic. Everything is pretty transparent on the backend. It is just point-and-go."
"I've used backup solutions like Veeam in the past, but Zerto seemed like a better, faster solution. We adopted Zerto because of the speed, and because we wanted to do everything in-house."
"The speed at which new files are created is something that could be improved. For example, if you create a new file in another country, I won't see it for between 10 and 15 minutes."
"I would like to see improvement in the training Nasuni provides. Compared to some of the other vendors out there, like Microsoft, where you can find how-to videos, Nasuni only has a lot of PDF documents that you have to go hunting for. It's workable, it certainly isn't a problem, but video walkthroughs would always be helpful."
"Nasuni recently implemented a health system for filers. However, it needs better visibility because it lacks data and an explanation, or reasoning as to why a particular filer may be unhealthy."
"The customer portal could be improved, but it has been a while since I've used it. They might already have improved it."
"We would like to have a user desktop agent to help improve the end-user experience."
"When users from one office save their changes, their peers in another office can see the changes within minutes. Of course, this is an area for constant improvement and we hope that they can still reduce the amount of time it takes to replicate changes."
"There is some room for improvement when it comes to monitoring. We are not using Nasuni monitoring. We are using our own monitoring through Xenos. Nasuni can provide better monitoring capabilities for us to monitor all the filers and NMC so that we don't have to use a third-party tool."
"I would like to see Nasuni provide the ability to mirror a Nasuni appliance from one site to another. They could maybe have a standby appliance that is mirrored in a different location for disaster recovery purposes. We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover. If we had the ability to have a mirrored appliance, we could flip over to that mirrored device and resume instantly rather than repopulate the local appliance with data from the snapshot history in the cloud. This is another feature that we would really like to see, if possible."
"We encountered some issues during Active Directory recovery."
"I would like Zerto to add support for VMware's lifecycle manager."
"Some of the ability to automate selections and automate VPG creations could be better."
"Zerto's solution could benefit from additional security features, such as malware scanning tools at the recovery site."
"The technical support has room for improvement."
"I don't have any input for improvement or a critical feature request at this moment. If anything, a lower price is always better."
"From the relationship standpoint, we have never had a local rep in South Bend, Indiana. It has always been somebody in Boston, and there is not a lot of communication. That is one of the big things. We would like help driving the business and talking to our sales people as well as more involvement from them. We could really utilize it more, drawing more customers in, but we need help with that."
"With the VPG (virtual protected group) it would be nice if you could pick individuals in the grouping instead of having to failover the whole group."
