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.

Cost savings and efficient data management improve operations but support quality varies

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. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

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

Pros

"It's easy to failover and failback"

"The stability of our ONTAP system has been awesome over the last four to five years, particularly with the software. The controls have been excellent as well. We recently went through a view of all of our systems and found a number of them had been up, over three years without any sort of reboots or downtime. We have been very happy with the stability of the systems."

"With the NetApp Data ONTAP Cluster, we get some features that are particularly helpful. For example, we can always add to and remove nodes from the cluster. The ability to move volumes online from the storage side, from one aggregate to another aggregate, or from one node to another node, keeps up the performance which helps us a lot."

"The performance of the hardware is good."

"One of the things I find most valuable is the way they do the Snapshots, taking incrementals at points in time... Often someone will say, "Hey, I deleted this thing yesterday, can you get this back for me?" It's good that we have all those incremental Snapshots at different points in time that we can refer back to, to get them whatever they need."

"The scalability is very good. It enables us to use different product lines within the same operating system."

"In terms of stability, I would rate NetApp ONTAP a ten out of ten because I have experienced nearly zero downtime over the complete year."

"It is very easy to manage in terms of system management and GUI management."

More NetApp ONTAP pros

"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."

"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."

"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."

"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."

"I would rate QoreStor a ten out of ten for what it offers for the price."

"Quest QoreStor definitely saved us money."

"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."

More QoreStor pros

Cons

"The toughest thing that we have right now is a cabling issue. There are so many that you need to connect."

"The vendor diagnostics, which allows for movement from one vendor to another vendor using the application technology that is available. It should be able to talk to any vendor, not just NetApp to NetApp. We should be able to replicate the data, so the next feature should not be vendor specific."

"I would like to see more in the public cloud space around things like object storage. A bit more granularity around how that gets deployed would be nice, but other than that I think they've got it nailed."

"There's a feature called multi-tenant approval. Currently, it's one size fits all. I cannot specify that one person is allowed to work on certain volumes, a second person on different volumes, and a third one on everything. It's all or nothing, so I would prefer it to be more precise regarding who could do what on which volume."

"The initial installation could've been quite easy, but there was a lot of miscommunications with professional services and there are a lot of details that they didn't quite provide which caused a very complicated installation."

"It takes them a few seconds to do a failover. I hope they can reduce this to milliseconds or at least drive it down to less than two seconds. Some of their competitors are already doing this."

"It's very expensive."

"There is a lot a lot of functional integration that we look forward to for improvements. I'm learning where they're going and I'm very interested to see those improvements and how they can help us."

More NetApp ONTAP cons

"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."

"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."

"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 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. 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 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."

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

More QoreStor cons

Pricing and Cost Advice

"We save a lot because of the deduplication and compression."

"Because of its manageability, we have fewer people managing it."

"It's not an all inclusive model. You have the option to purchase modules to make the entire ecosystem coherent. I would like the option to pay one price and get everything all inclusive, like OnCommand."

"ONTAP has helped our organization reduce its overall cost of storage (somewhere in the high millions)."

"They could reduce the price."

"NetApp is streamlined, reducing costs."

"With other vendors, we need to buy a separate license for a third-party storage, but with NetApp, you don't need to buy a license, as it will come up with the storage."

"In the past, you didn't have to buy separate products. They were mostly included with the purchase. In the end, it's more expensive to buy it separate than together. If you are going to need it, one package at the beginning is cheaper."

More NetApp ONTAP pricing and cost advice

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

"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."

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

"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."
