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.

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."

"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."

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

"It is a stable solution."

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

"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."

"The solution offers good documentation."

"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."

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

More Quorum OnQ pros

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."

"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 cost could be reduced."

"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"

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

"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 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."

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

"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."

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."

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

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

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

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

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

"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."
