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

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

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

"Quest QoreStor definitely saved us money."

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

"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 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."

"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."

"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."

More QoreStor pros

"The most useful feature is the one-click recovery."

"The most valuable feature is spinning up a ready-to-go VM in a test or production environment that is based on a backup stored on the Quorum device."

"Quorum OnQ has a good ransomware protection feature, and customer service and support were very good."

"It is a very scalable solution."

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

"I like this product because it is easy to use."

"One of the biggest features is that, even on the absolutely run-of-the-mill box, if I lose any one of my servers I can automatically bring it up virtually on the physical onQ Quorum device."

"The solution is very cost effective."

More Quorum OnQ pros

Cons

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

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"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."

"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."

"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 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 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."

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

More QoreStor cons

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

"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 technicians they have are great. They are fantastic, but it seems difficult, at times, to get in contact with anyone."

"There was a situation I faced in the past when I contacted the tool's support team, and it took them a while to respond."

"I would really like it if they followed comparable products from other vendors and had an option where you could offload to tape. I know it sounds incredibly antiquated, but the benefit I see is that there would be a better air gap than you have with backing up to an online source."

"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."

"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."

"The user interface needs to be improved."

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

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."

"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."

"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."

"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 solution’s pricing is economical."

"The initial expenditure for us was a little under $40,000 for the recent renewal. For the first three years after that, other than electricity, there's no cost. After that, their support contract has to be renewed annually. We spent close to $6,000, between the two offices, for support."

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

"The cost is higher than other software and services, but it is an absolute must-have."

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

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