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

"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."
"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."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"Quest QoreStor definitely saved us money."
"This is the best money I spend on my budget."
"The most useful feature is the one-click recovery, as it instantly boots up the protected VM and this product is easy to use."
"The most useful feature is the integration and ease of backup and testing."
"It is a stable solution."
"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."
"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."
"A very high level security environment for secondary data."
"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."
 

Cons

"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."
"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."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"The ransomware protection of QoreStor could use improvement."
"The air gap feature is something I'd really like to see in QoreStor."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"At times the email notifications don't go out, but a quick reset always fixes that problem."
"The more basic versions do not scale."
"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 price of Quorum OnQ could be improved."
"Better integration with cloud-based solutions like Azure and Office 365 is needed."
"Quorum OnQ's user interface is not very attractive and should be made more attractive."
"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."
"I don't love the scheduler, as I think that interface could use an overhaul."
 

Pricing and Cost Advice

"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"The upfront cost of purchasing a license for the hardware is quite steep."
"When we quote the price of Quorum to customers, they find it expensive."
"I am not sure how much it costs, but I know it's expensive."
"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."
"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 total for our current solution's licensing is about $14,000 for 12 servers for three years."
"The solution’s pricing is economical."
