Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

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

"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."
"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."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"Having Quorum gives us 100 percent uptime."
"A very high level security environment for secondary data."
"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."
"It is a very scalable solution."
"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."
"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 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."
"Quorum OnQ has a good ransomware protection feature, and customer service and support were very good."
 

Cons

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The air gap feature is something I'd really like to see in QoreStor."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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 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 setup of the software is definitely not the easiest thing in the world."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."
"At times the email notifications don't go out, but a quick reset always fixes that problem."
"The solution could do more by improving compatibility in terms of supporting other OS."
"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."
"It would be beneficial if file culling could be more granular."
"Upgrading the software on the appliance feels to me like it's going to be a little bit more work than I originally anticipated."
"The user interface needs to be improved."
"Quorum OnQ is limited and does not support all the Linux flavours, and it currently only supports Red Hat-based systems, for example, Ubuntu is not supported."
 

Pricing and Cost Advice

"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 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 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."
"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."
"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 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."
"The solution’s pricing is economical."
