Head IT at TO THE NEW Digital

Provides good performance, stability, and complete data security

Our upcoming investments would be prioritized around a hybrid cloud solution because we ourselves promote the cloud in the market. We are the premium service provider for AWS, so we have that inclination toward cloud computing. From the experience that we had during the pandemic, we are looking for some kind of hybrid solution for our environment. NetApp should focus on a hybrid cloud solution because none of the media houses are opting for cloud storage. The files are quite heavy, and it becomes quite difficult to maintain them on the cloud. If NetApp can provide such technology and fill the gap of storing media files in the cloud, it would give them an advantage.

Cost-efficient, highly scalable, and installable on different types of hardware

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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"Snapshot and SnapMirror technologies make it easier to replicate data to disaster recovery scenarios."

"Overall, for us, it's the stability, it has a solid infrastructure. It's easy to use, easy to rack and configure and start utilizing really quickly. It's been very stable, it works great, and it does everything we would want it to do."

"It is able to store a lot of data, and we can manage it with fewer people."

"The most valuable features are the data deduplication, the inline compression/compaction, and the encryption as well, the security aspect of it."

"You can scale it however you want, depending on your data center footprint."

"The solution is very easy to configure."

"My experience with NetApp is its very easy to learn and intuitive. I can figure out just about everything."

"It gives us a location to store data across multiple mount points."

More NetApp ONTAP pros

"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."

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

"Quest QoreStor definitely saved us money."

"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."

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

"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."

"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."

More QoreStor pros

Cons

"The only thing that they have to improve in NetApp is that they're still relying on padding each node in active/active in CDOT. That has to go away. They should look at the scalability on a platform level. The computer will have that one file system with multiple nodes on it. If even one node fails, any node in that cluster could take over the functionalities. But today, it absolutely relies on that active-active uncoupling it. That needs to be improved in such a way that it would be one namespace. If this node goes down, any node in the cluster should take over and run that environment."

"The back-up side of the solution could be improved, as could the archive. We still have to rely on third-party backup programs and other archiving solutions. If it was offered by NetApp itself, it would be much better."

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

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

"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."

"With our current use case, we will need something faster. E.g., if you have a huge scale, having SSD-based backup is better."

"Technical support has gone down in my perspective. When getting to the root cause of issues, they need to respond faster."

"There is room for improvement in areas related to hardware constraints—for example, more storage efficiency, especially in terms of deduplication."

More NetApp ONTAP cons

"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."

"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."

"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."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"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 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."

More QoreStor cons

Pricing and Cost Advice

"With the duplication and compression, we have been about a one and half to two times savings since we are not running all-flash."

"NetApp ONTAP is moderately priced."

"We received a super deal for our new machine, so we were happy with the price."

"The licensing prices are really high."

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

"I rate NetApp ONTAP's pricing a seven out of ten."

"It helps us save money using compression and deduplication."

"Our pricing with discounts is reasonable, but it may vary for others."

More NetApp ONTAP pricing and cost advice

"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."

"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."
