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

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

"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."

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

"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."

"Quest QoreStor definitely saved us money."

"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."

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

"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

"It is a stable solution."

"From a disaster-recovery point of view, one of the things I really like is that I can test the virtual copy of the physical server on a test network and compare the servers side-by-side, without interfering with the production network. So I can see and make sure that the latest copy of the server is the physical copy of the server, without interfering with production."

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

"The biggest feature is being able to do a file recovery to the original server. That is extremely useful and has saved us a few times when we've had ransomware. In some of those cases, people's computers were locked down by viruses which spread to things they had access to, including server shares. But we were easily able to just restore to four hours prior, instead of a day or two or more ago."

"The solution is very cost effective."

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

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

"It is a very scalable solution."

More Quorum OnQ pros

Cons

"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."

"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."

"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."

"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."

"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."

"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."

More QoreStor cons

"It feels to me like it's going to be a little bit more work than I originally anticipated when upgrading the appliance. I haven't done that yet so I can't speak from true experience, but I went through the project plan and it feels to me like there's quite a number of pieces and components and things that have to be done. Quorum is going to manage the rollout, but in starting the initial conversation there were a lot of unanswered questions"

"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."

"The one thing they could do is some tweaking on the web solution that's supposed to monitor everything from one page, rather than having to bring each server up on its own webpage. It doesn't always accurately show what the system's state is at the time, and we have to restart that process now and then."

"The cost could be reduced."

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

"Quorum OnQ's user interface is not very attractive and should be made more attractive."

"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."

"Better integration with cloud-based solutions like Azure and Office 365 is needed."

More Quorum OnQ cons

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."

"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."

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

"The pricing is about $1,400 a month. It's a little bit on the higher side. But it's one of those situations where time is valuable for me. So if it costs a little bit more money for me to have a solution that just works and requires less of my day-to-day management, I'm willing to pay a little bit more."

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

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

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

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

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

"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."

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