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.

Enhanced filtering for advocate emails

Quorum provides an elevated ability to filter on everything from people's location to age to their voting history. This is an extreme feature that will help our advocacy department a lot. It encompasses the ability to formulate emails and calls to action across regions. Their platform is more advanced than our previous one. It provides a smooth training experience and easy terminology for those in the advocacy world.

Quotes from Members

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

Pros

"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."

"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."

"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."

"Quest QoreStor definitely saved us money."

"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."

"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."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"Quest QoreStor is very stable compared to our previous solution."

More QoreStor pros

"Quorum OnQ provides an elevated ability to filter on everything from people's location to age to their voting history."

"One of the most valuable features was the usability, since many of the features were very straightforward. The backup and restoration process was also very fast. Although we weren't able to fully test the scenarios, one of the features was that we could have it restored on a remote site. However, since we were on-prem, we weren't able to test the remote site restoration."

"The most valuable feature of Quorum OnQ is quick recovery."

"A very high level security environment for secondary data."

"The solution is very cost effective."

"It does automated tests to the systems to make sure that you could spin them up if you needed to. And if something doesn't come back up in those tests, we get a notification saying the system didn't come back up."

"The change in the way that Quorum processes data has made a tremendous improvement in backup and replication times. While the familiar interface remains, the underpinnings have been finely tuned and the speed is incredible. My large Exchange Server went from 5- to 6-hour backups down to 22 minutes."

"Quorum OnQ has taken the guesswork out of backup/recovery and disaster recovery."

Cons

"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."

"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 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."

"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 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."

More QoreStor cons

"They have radio buttons that allow multiselection, which is not intuitive. Also, the URL for our environments is the same, making it confusing for management when handling different departments with different needs."

"At times the email notifications don't go out, but a quick reset always fixes that problem."

"It would be beneficial if file culling could be more granular."

"Quorum OnQ can be improved by providing support for other operating systems like Ubuntu."

"Upgrading the software on the appliance feels to me like it's going to be a little bit more work than I originally anticipated."

"Lacks compatibility in terms of supporting other OS."

"There seems to be a lack of technicians. Sometimes they are very busy and I don't hear back for a day or two."

"The price of Quorum OnQ could be improved. We were exploring the product in terms of having a partnership with the distributor so that we could operate as a service, but for our own use, within the company, we couldn't justify the price unless the servers would become an option later on. The upfront cost of purchasing a license for the hardware is quite steep."

More Quorum OnQ cons

Pricing and Cost Advice

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

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

"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."

"The total for our current solution's licensing is about $14,000 for 12 servers for three years."

"The solution’s pricing is economical."

"When we first got the Quorum the licensing was different."

"I am not sure how much it costs, but I know it's expensive."

"When we quote the price of Quorum to customers, they find it expensive."

"We have never questioned whether it is worth it because it so obviously is a great value."

"Quorum OnQ can be described as a medium-priced product...There are no ingress and egress charges in the product."

"The upfront cost of purchasing a license for the hardware is quite steep."
