Unified cloud file storage has simplified global data management and reduced operational overhead

From an admin perspective, Nasuni has various valuable features. The GUI is very good, upgrading is very easy, and DFS is very easily manageable. Compared with other products, the snapshot feature is beneficial because it creates a snapshot every five minutes, allowing me to provide restores very easily to customers. Data protection is enhanced by the fact that Nasuni uses S3 technology to create snapshots every five minutes and enables versioning, so the snapshot is created and I can utilize that snapshot for disaster recovery or restore purposes. I assess the value of global file locking and caching for reducing latency as good, giving it a five out of five.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options

The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We have one platform to manage all of our data, to see it and to quickly access it, and that is huge."

"My clients are happy with Nasuni because the transmission is seamless, and it consolidates all the existing file servers into one location. Also, Nasuni has no boundaries. It's infinitely expandable. They don't have to rely on the service provider for backup and restoration. It's self-serve."

"Nasuni has replaced multiple data silos and toolsets with a single, global file system."

"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."

"Nasuni has helped decrease capital costs by 66% since we don’t need to buy as much excess capacity."

"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."

"Nasuni reduced our overall storage footprint at our sites by 70 to 80 percent."

"We like Nasuni's snapshot technology. The snapshot and recovery features are the things we use most frequently. Ideally, I would recommend NFS or CFS, which gives you more benefits for clients or anyone who wants to access FTP protocol, FTP utilities, SAN, and MSS."

More Nasuni pros

"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."

"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."

"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."

"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."

"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."

"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."

"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."

More QoreStor pros

Cons

"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."

"Customer support and response time on issues should be improved because their support can be hard to get in touch with and we have to wait for a long time to get a call back."

"The user-friendliness of its access needs improvement. When I log into the console, I see all the files that we handle globally. There are hundreds of Nasuni files that I can see on the console, but no way that I can filter them down. While this is a small thing, I need to scroll down and select the ones that I want. "Control F" doesn't work nor is there a dropdown menu that I can click on and select the ones that I want."

"Nasuni could improve cloud integration and documentation of various ways we can leverage the product. It integrates with Azure, but the native Azure File Sync solution lets you divide data into tiers like hot, cool, and archived. Nasuni doesn't allow you to break the data apart into those tiered categories."

"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."

"Its interface design or the graphic user interface design can be slightly tweaked in some areas. Some built-in setup wizards would be very beneficial. Rather than having to go in and configure it by hand, there should be more setup wizards for onboarding new data shares and getting it set up the way you want. I don't know if these are on their roadmap, but I sat down and talked to them about some of the work concerns, some of the things that we liked, and some of the things that we didn't like. They are probably working on that."

"Nasuni is not a stable solution."

"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."

More Nasuni cons

"The ransomware protection of QoreStor could use improvement."

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."

"The setup of the software is definitely not the easiest thing in the world."

"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."

"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."

More QoreStor cons

Pricing and Cost Advice

"Nasuni pricing is average; it's not too high or too low."

"It is around $850 per terabyte per year. Any additional costs that you would incur are for the local caching devices that you'll need to access Nasuni. You kind of provide your own virtual machines or compute to access the data. You also pay for the object storage. So, there are three parts to it. There is the Nasuni license per terabyte. You would also pay for the actual object storage in the cloud, and then you would pay for virtual machines to access the storage."

"Our agreement is set up such that we pay annually per terabyte, and we buy a chunk of it at a time. Then if we run out of space, we go back to them and buy another chunk."

"It has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."

"I would not say it is economically priced, but it is affordable. If you can afford to pay for it, it is worth the money, but it is definitely not overpriced. It is priced about where it needs to be in the market. We were satisfied with the way they did their licensing and how they handled it. I believe they actually license by data size. It is based on how much data is being held on the machine and replicated, and that's completely understandable. So, for us, their pricing was as expected and affordable."

"The pricing is on par with everybody else, and fair."

"Its price is fair and reasonable. I don't have anything negative about its pricing and licensing. For us, there is also the cost of monitoring. We are monitoring through Xenos and not through Nasuni. That is another cost for us from the monitoring perspective, but as far as Nasuni goes, we don't have any other cost apart from the licensing fee."

"The pricing is fair. It's an enterprise-level solution so it's not inexpensive... The cost is pretty stable year over year."

More Nasuni pricing and cost advice

"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."

"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."

"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
