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

"Today, because NetApp listened to their customers and improved their GUI, we can perform a firmware upgrade within minutes."
"The performance of the hardware is good."
"It has also helped us reduce our overall cost of storage. Through dedupe and compression, we save a lot of capacity. Without that, we'd obviously have to buy more capacity. The last time I checked we were saving about 40 percent over our previous storage."
"It has the ability to bring up disaster recovery quickly."
"Snapshot and SnapMirror technologies make it easier to replicate data to disaster recovery scenarios."
"Overall I think it is still a really good environment and using NetApp has been a really good solution for us."
"Technical support is good. NetApp's solution engineers are good at architecting designs which are standard, but also future thinking. I've only opened a few tickets, and they've answered my questions each time. NetApp takes less than four hours to respond."
"We are saving more disk space which saves us more money."
"Quest QoreStor definitely saved us money."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
 

Cons

"We're at 9.3 so when we go to 9.5 we would like the synchronous SnapMirror because our users would like that, especially the ones that do the conveyor belt of data. We'd like that."
"The product costs an arm and leg; it's expensive."
"It should be easier to put in tech support cases. They should streamline the online support and chat."
"The config could be a little easier."
"The licensing prices are really high."
"In the future, we are going to migrate to Windows-based platforms. I want to see if we can achieve similar control and implementation with Windows, basically installing NetApp ONTAP onto a Windows machine and not just onto the Linux machine."
"If the customer wants to integrate with another product they need deployment guides."
"We would like to have additional cloud integration and the ability to Snapshot directly to Amazon. This would help us reduce costs, provide us additional disaster recovery, and give us a site that's not owned by us."
"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. 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."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
 

Pricing and Cost Advice

"Additional costs exist if you want a license for a feature like SnapMirror."
"Depending on the licensing you choose the price varies. For our company and our needs, the cost is very fair."
"At first, it's expensive. Once you start using it, it's not that expensive. When you see all the benefits, it's acceptable. It could always be better, but you get what you pay for."
"If you start narrowing down NetApp versus price point, then comparing it to the feature set and take away all the bloat that other companies will try to add on, there is no other option. It comes down to just NetApp."
"There are two consumption methods: pay as you go and subscription. Pay as you go... is a little expensive but worth it."
"I rate NetApp ONTAP's pricing a seven out of ten."
"NetApp is streamlined, reducing costs."
"The data compression and deduplication have kept us from buying more disks these past three years."
"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."
"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."
