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.
"Nasuni has helped to eliminate on-premises infrastructure. We were using about eight to 10 different types of vendors or small storage boxes for provisioning and shared access for users. We got rid of all those. That has eliminated operational overhead and footprint at our data center. We don't have to worry about any hardware or monitoring particular devices, and hundreds of devices have been decommissioned. Now, for provisioning, everything is on Nasuni. I assume this has made a big difference in costs."
"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."
"With Nasuni Management Console (NMC), we get a single, centralized view of our entire internal structure and data center structure. This is very important because this caters to remote locations. One of the main care center teams is dependent on this solution. As it is directly connected to customers for the calls that they receive and troubleshoot, they can then help customers out in case they are not able to place an order."
"The disaster recovery capabilities are very easy because their virtual appliances are just like OVFs or images. You put in a code and it collects all the configuration from the cloud and then builds up the cache. But that doesn't preclude the device from easily being restored or recovered at short notice."
"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."
"Nasuni offers us a single platform with a 360-degree view of our file data, which is definitely important to us. It simplifies IT operations tremendously. Because it is taking continuous snapshots, it eliminates a lot of work that was done previously when trying to manage backing up and restoring data files."
"The nice thing about Nasuni storage is that it is immutable. This means the data is only written once. So, you never modify the files. When you write a file out to the storage, it doesn't modify it when you change it. The technology knows how to figure out what the difference is between the original file write and what the changes are. Therefore, it only saves the changes."
"Managing the system is easy and reliable, you can choose any VM you want to replicate to your DR Site in Combination with other VM's."
"It reduced the time for DR tests from the infrastructure side. Being able to get our work done in a matter of a couple of minutes so the app teams can get to work and can do their testing has been significant."
"Zerto offered us massive time saving and consistency. We have a consistent outcome every time we complete conversions."
"The most valuable features are the continuous streaming, that it takes very little CPU usage — it doesn't affect production — and the recovery time is very short."
"Zerto offered a very good front-end GUI for orchestration. The graphic interface was very good."
"We are in the process of switching over our production data center and Zerto has been a true time-saver that has cost us zero downtime."
"You can set the number of days a VM can be rolled back in case of corruption or virus infection."
"The most valuable tool is the dashboard, which allows us to immediately check the DLP status, replication data, and all other data needed to have cleaner and immediate control of the situation."
"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."
"Some applications may not be suited for the Nasuni environment. You may need something with better performance. Otherwise, if you want to run daily operations or some file system, it's a good bet."
"The only issue we face with Nasuni is from the performance perspective. Sometimes, when we deploy a Nasuni device, it doesn't meet our requirements. It's a capacity-planning issue."
"It would be helpful to have more built-in analytics tools to compare the storage costs between the various cloud providers. I would also like some graphing capabilities. We had a tool called Grafana that we used for graphing. I think some more visual analytics like that would be nice."
"One thing to consider is that Nasuni will have the same limitations that a traditional file storage solution will have, although that is because they are taking the place of a traditional architectural model. For example, Office 365 supports collaboration on documents such as Excel files and Word documents, but because Nasuni is a traditional file server, in that sense, it can't make use of that functionality."
"The Nasuni file storage platform doesn't work well when there are a high number of small files. This is the case when a directory structure contains more than 10,000 or 20,000 small files, e.g., 5 KB, 10 KB, or 15 KB. When the user is accessing these files from another geographical location, they might face a slow response or timeouts when connecting to the shares, and then to the files. This is because the file size is small. There is a scope of improvement with this solution when it comes to accessing a large number of small files."
"It is difficult to configure Nasuni. Adding a filer is an easy task, but deciding where to add them, how many to add, and what size to add takes a lot of time. I have to analyze my existing storage to understand how many users are going to access which folders. I have to design the Nasuni architecture accordingly."
"We forecasted that the data at my client's organization would grow by about ten percent annually, but we are migrating more data because we are bringing in some servers that had not previously been within the scope of our license. We expected it would take us two years to reach a specific amount of data, but we hit that mark in one year. The licensing cost skyrocketed, so we need to renegotiate. It puts us in a bind because we are reliant on Nasuni for our service strategy. We can't deny our customers, but we also struggle to pay for that."
"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 am a little bit worried about how Zerto will work with large volumes of data, such as replication for big data and very large files."
"If they already do not have it, they can have some APIs for the Horizon environment. Instead of having to use some scripts to get around, they can make it a lot more user-friendly for integration."
"Compared to other products, I would praise the intuitiveness of the product. But I think that can always be improved. The intuitiveness of the graphical user interface, while it is very solid and I don't have issues navigating it. I would say that it can always be improved."
"The onset of configuring an environment in the cloud is difficult and could be easier to do."
"We do have some sites that are very low-bandwidth sites. Zerto is able to set throttling in the solution, but the throttling is set at a site-wide level. In those instances that have very low bandwidth, I can't reduce the throttling on that site. It would be nice if there were a way to control the throttling by the protection group for a specific workload."
"They could improve their online documentation."
"We encountered some issues during Active Directory recovery."
