Expert Backup at a tech services company with 201-500 employees

A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments

Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

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

"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."

"I am impressed with the tool's technical alliance with Veeam and Veritas."

"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 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."

"It's easy to implement, easy to spin up, easily configurable, to drop-in appliances and network. There wasn't a lot of time needed to spin it up."

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

"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."

"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."

"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."

"When it comes to recovering what you need from a backup, it's really easy. You just drill through the directory, find the file and the date that you want, and click to recover. You then pick the directory you want to save it in. Usually, it takes a minute or two and it's done. It's quick and easy."

Cons

"The product needs to improve performance while scaling out. It also needs to improve stability."

"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."

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

"One thing that could be done to improve it would be a single pane of glass for doing disaster recovery testing, where I could have remote consoles in one place... I still have to go to each location in a browser and then bring up the console. I'd like to see them integrate that into a single pane of glass so I don't have to go to each server."

"The user interface needs to be improved."

"I would like to see iSCSI support added so that NAS storage servers could be protected. We heavily utilize NAS storage and the risk there is minimal backup options. Currently, we are backing up NAS to NAS which is costly and slow. Being able to integrate NAS server backup would be the last item on my Quorum bucket list."

"They have radio buttons that allow multiselection, which is not intuitive."

"They need integration with other platforms."

"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."

Pricing and Cost Advice

"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."

"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."

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

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

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

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

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

"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."
