Quest QoreStor's flexibility allows it to run on various hardware, including virtual machines, making it adaptable for different backup workflows and processes.
The integration with numerous backup software solutions enhances compatibility and supports the continued use of existing backup infrastructures.
Quest QoreStor is praised for its stability and cost-effectiveness, with deduplication and compression as key features providing substantial storage savings in the cloud 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.

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.

Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future.

This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large.

QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing.

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.

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.

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.

Quest QoreStor Cons review quotes

Apr 14, 2021
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 management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive.

They need to increase their maximum capacity. Other than that, they're doing a pretty good job.

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.

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.

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 ransomware protection of QoreStor could use improvement.
