Cloud data management that achieves cost efficiency with advanced data protection features
I am currently using Nasuni for seismic data. We have a huge data size, and we want to reduce costs. Nasuni acts as a caching solution, so we put some data into the cache, and the rest goes to the blob, which helps us save on costs. We use it for applications like Petrol and Tech Log, where 3D…

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

"I can see who is logging in on files from all over the globe. For example, if a file is locked, maybe a user in Shanghai has locked files or something, I can see that from the Management Console, then unlock the file."
"Nasuni is helping us replace multiple data silos and toolsets with a single global file system."
"Nasuni reduced our overall storage footprint at our sites by 70 to 80 percent."
"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 most valuable feature is that we have redundancy in our data. It's nice to know that it is cached both locally on the filters, as well as stored on that cloud."
"My advice for anybody who is considering this product is that it works great."
"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."
"The OR and DR capabilities have been a very big help for us, reducing what used to take weeks to fix and bring back up and running for people down to a matter of minutes while keeping their experience seamless, no matter how much trouble the hardware is in at the site."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"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."
"Quest QoreStor definitely saved us money."
 

Cons

"Room for improvement would be the speed of replication of new files. I would also like to see cloud mirroring."
"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."
"As administrators, we are used to having control equal to managing an on-prem device. In terms of log analysis and other things we want to do, Nasuni has some limitations limitation on what you do on the Nasuni. Nasuni could add some features to the GUI that make administration a little easier. It's tough when I have to move from one filter to another because there is no way to search it. We have to scroll up and down to find the name of it."
"We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover."
"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."
"We've had some organizational changes that Nasuni has not been able to keep up with, mainly from a data or file system perspective. Moving a filer from one management console has been a challenge. It lacks the flexibility to move files in and out of the management console. We have six management consoles now, and we're constantly telling Nasuni, "Hey, please allow us to move a filer from management console A to B." They can't do 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."
"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."
"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."
"The installation could use improvement. The initial installation was a little touchy and it's not really user-installable. You have to have a connection to support to install."
"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The ransomware protection of QoreStor could use improvement."
"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."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
"The setup of the software is definitely not the easiest thing in the world."
 

Pricing and Cost Advice

"The pricing is on par with everybody else, and fair."
"With this solution, the license renewal is pretty swift. With the virtual appliance, you just need to take care of the OS versions and patches. In a way, we don't have to struggle much with renewals because the only thing that we need to take care of are the licenses. We renew it every three years. This aspect goes with infrastructural costs because it doesn't cost us too much to maintain the solution."
"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."
"The cost of licensing is negotiated and billed annually per terabyte."
"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's cheaper than a lot of alternatives but it's not cheap."
"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."
"Its pricing can get a tad expensive. When we first took Nasuni out, we were just paying for the service. We got storage at a reduced rate. It has now changed, and they're now more of an all-in-one type of thing. It can be quite expensive, but it works out. Apart from that, licensing-wise, it's very simple."
"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 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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
