Data management and availability improve operations, but cost and support need attention

For snapshots, there should be something similar to a recycle bin. When someone mistakenly deletes a snapshot, it should be stored for about two days before disappearing from the system. Regarding storage optimization, when purchasing a 10 terabyte disk, after formatting, you can only use approximately 8 terabytes. They should improve this so users can utilize 90% instead of 80% of the disk space. The support response needs improvement, especially for P1 cases. When critical cases are raised, they should ensure they call the customer and follow up properly. Comparing NetApp ONTAP to other solutions such as EMC, the cost of contract renewals and warranties is relatively expensive. They should extend their renewal window beyond the current six months to one year options. A longer warranty period of two years for new systems, controllers, or filers would be beneficial. Overall, they should reduce subscription costs for businesses.

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

"The initial setup is pretty straightforward."

"It's extremely reliable, very easy to manage. I've been able to reduce the number of people I have managing the storage systems because of the software."

"Queries are being completed in less time. For example, we have seen a three times improvement when it comes to running a query. If query used to take an hour, now it takes 10 to 20 minutes."

"ONTAP's technical support is awesome and always ready to help."

"The solution is very easy to configure."

"Its usability, scalability, and dependability are very good."

"NetApp has come up with performance management devices to improve the performance, and it has all-flash and hybrid aggregates to improve performance in caching."

"Deduplication, data protection, and NetApp block are some of the valuable features of the product."

More NetApp ONTAP pros

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

"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."

"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."

"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."

"Quest QoreStor is very stable compared to our previous solution."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"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."

"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."

More QoreStor pros

Cons

"They could also improve on their ability to back up storage."

"The product costs an arm and leg; it's expensive."

"For administration, there is no user interface present for NetApp ONTAP, so I have to rely on the ONTAP CLI."

"You really need OnCommand to do a lot of cool stuff with NetApp, and they make it hard to get."

"It's very expensive."

"It is not as good as we need from a performance perspective. At the moment, we are always running out of CPU on the controllers, even the high-end solutions."

"It would be nice if they make it so that one can operate the console without the need for interface-related comments."

"The pricing is high."

More NetApp ONTAP cons

"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. 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."

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

"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."

"The air gap feature is something I'd really like to see in QoreStor."

"The ransomware protection of QoreStor could use improvement."

"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."

"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."

More QoreStor cons

Pricing and Cost Advice

"The price could be a little bit cheaper, but you get what you pay for."

"This solution has helped our organization reduce our overall cost of storage. We're part of the NetApp OnDemand, where we lease it. Also, it doesn't take as many people to administer the solution as some other products."

"NetApp is streamlined, reducing costs."

"This solution helped our organization reduce our overall cost of storage. Because idle data which was residing on high cost tiers, once we sifted the ONTAP, we were able to scale and place it where it should be, then offload the data which was unnecessary to different locations."

"The product costs an arm and leg; it's expensive."

"We have seen ROI as we can fit a lot more storage in one rack."

"NetApp provided the features required within our cost limit."

"The licensing prices are really high."

More NetApp ONTAP pricing and cost advice

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

"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."

"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."
