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 most useful feature is the one-click recovery."

"The most valuable feature of this solution is its ease of use."

"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."

"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."

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

"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."

"It is a very scalable solution."

More Quorum OnQ pros

Cons

"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."

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

"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."

"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."

"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."

"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."

"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"

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

"I don't love the scheduler, as I think that interface could use an overhaul."

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 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."

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

"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."

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

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

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

"The solution’s pricing is economical."

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