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.

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

"The deduplication engine. Right now, we're at about 10.5 to 11 times deduplication of our backup data."
"The solution can be used for all Office 365 applications."
"It's so easy to work with."
"Most importantly is having that island into that datacenter, and being able to address things in the same console. Thus, it is irrelevant where it's stored."
"Being able to move data seamlessly from one-premise to the cloud (Azure). It works great. The backup solution is perfect for us."
"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."
"Its initial setup is easy."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"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."
"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."
"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."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
 

Cons

"It would be nice if the solution was more complete. Many customers are looking for a single solution or silo that they can manage everything from. It would be nice, instead of having different products, if everything a client needed was in one solution."
"The product must provide multi-gate connectivity."
"The solution needs faster indexing."
"The initial setup phase of the tool was difficult."
"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."
"It's a good product, but it's becoming outdated and moving to their other primary architecture."
"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."
"The initial installation is difficult for my clients who have it on both on-premises and on cloud."
"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 ransomware protection of QoreStor could use improvement."
"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."
"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."
"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."
 

Pricing and Cost Advice

"It's quite cost-effective."
"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."
"The pricing is not too bad, but could be a little better."
"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."
"It is a rather expensive program."
"There is a need to make yearly payments towards the licensing costs attached to the solution, which comes to around 3,000 USD."
"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 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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
