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

"We do not face any glitches or downtime."
"Clustered ONTAP makes it very easy to manage large amounts of data, measured in petabytes. One person can manage all that."
"The initial setup was straightforward. It came in a box ready to go."
"Overall I think it is still a really good environment and using NetApp has been a really good solution for us."
"The most valuable feature is the very high IOPS rating which you can achieve with it and the customization capabilities of the storage are very feature rich."
"The product is good at deduplication. Also, the new automation feature is good, as it saves us a lot of time."
"The scalability is very good. It enables us to use different product lines within the same operating system."
"It's much easier and faster to deploy our storage with ONTAP than some of the other solutions that we have."
"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."
"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."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"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%."
"Quest QoreStor definitely saved us money."
 

Cons

"In terms of areas where NetApp ONTAP could be improved or enhanced, I believe they should improve the volume replication, specifically the synchronous replication in a block-based SAN environment."
"I would like to see more integration of the features with the CIFS and SMB Protocols. We also want integration with iSCSI."
"Sometimes, we have had some delays, on holidays and weekends, getting the right resource for a specific problem."
"I would like it to be more user-friendly. When you open the main dashboard, anyone should be able to know exactly what is going on, even without a tech background. Minimal training should be required."
"The config could be a little easier. It's not entirely difficult, but it could be a somewhat easier. I have seen other vendors make it easier."
"Technical support is hit or miss sometimes. Level 1 support is not very good."
"The back-up side of the solution could be improved, as could the archive."
"The toughest thing that we have right now is a cabling issue. There are so many that you need to connect."
"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 ransomware protection of QoreStor could use improvement."
"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. 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 air gap feature is something I'd really like to see in QoreStor."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
 

Pricing and Cost Advice

"There are specific workloads where some vendors provide better value, but in general, NetApp has done a far better on price than other vendors."
"It has been cost-efficient. Compared to our legacy Dell infrastructure, we have realized cost savings. It is good."
"We have seen ROI as we can fit a lot more storage in one rack."
"We have a wholesale contract with NetApp. We also have NetApp ONTAP On-Demand activation for certain things. We also have some preferential pricing for licenses. The licensing that I see here doesn't apply to other clients in the field. NetApp is expensive, but so are the competitors, making it hard to ascertain precise retail value. However, based on my perspective, NetApp pricing appears competitive."
"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."
"Our pricing with discounts is reasonable, but it may vary for others."
"It is cost-effective for the benefits you get."
"ONTAP has helped us reduce the cost of storage by a lot. We were using IBM XIVs and were paying high costs, except for the maintenance. Now, we are on all-flash and we pay less than what we used to pay."
"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."
