Positive impacts seen with improved data security and reliable support
I have six months of experience with the product, and as a consultant, the use cases for NetApp AltaVault mainly stand out for me. Regarding the deduplication feature in the product, I am interested in whether clients are using it. There are different integrations available with NetApp AltaVault, such as AWS, Microsoft Azure, Google Cloud, and I want to understand how they impact data security policies in my case.

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

"You can store backups for a while."
"The deduplication engine. Right now, we're at about 10.5 to 11 times deduplication of our backup data."
"We're doing AWS S3 with Glacier with cloud-based backup and the integration is good, as it works with Veeam and Commvault."
"Our restore window has been cut by 10 times, from having to pull back from tape - I'd definitely recommend it."
"The solution is very easy to use and it offers great support."
"The most valuable features of the solution stem from the fact that it is easy to use and integrate with whichever operating systems you use, providing you with a complete view, especially when you plan to migrate to some other operating system."
"It's pretty simple. Once you set it, it goes; and then the idea of being able to get it to the cloud very quickly. It's kind of a set-it-forget-it."
"Able to reduce administrative burden on tape management."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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."
"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."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"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 to reduce our backup storage requirements on-premise by at least 90%."
 

Cons

"What could be helpful is different user base authentication so then maybe we could allow different customers to point to a single appliance and they only see the backups and things that they have."
"More than a 500 volume limit. At the moment, it only supports up to 500 volumes for SnapMirror and that's a problem. We've got 750, so a larger limit for volume replicas for SnapMirror."
"We have had issues getting to the right person, but once you get to the right person, they are knowledgeable."
"NetApp's own competing products complicate things."
"The initial installation is difficult for my clients who have it on both on-premises and on cloud."
"I don't actually use the solution."
"We've had a lot of issues, crashed the service console a lot, service crashes."
"It's a good product, but it's becoming outdated and moving to their other primary architecture."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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 air gap feature is something I'd really like to see in QoreStor."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The setup of the software 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."
"The ransomware protection of QoreStor could use improvement."
 

Pricing and Cost Advice

"It is a rather expensive program."
"The pricing is not too bad, but could be a little better."
"There is a need to make yearly payments towards the licensing costs attached to the solution, which comes to around 3,000 USD."
"It's quite cost-effective."
"The price is a bit high."
"In one use case, and we have several, to run for a particular customer, the price is about $375,000 a year."
"You could compare it to a Dell EMC or ECS, and I think it's probably a little less costly than that. Within the marketplace, it's a medium cost."
"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."
"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."
