Prominent pros & cons

PROS

Quest QoreStor offers impressive deduplication and compression rates, achieving up to 76% deduplication and nearly 50% compression in the cloud.
Deduplication is highly valuable, significantly reducing storage space, with 100 terabytes of data only requiring 5 to 6 terabytes on disk after processing.
Integration with various backup software makes Quest QoreStor compatible with existing workflows and processes.
The flexibility to install Quest QoreStor on different hardware types, including virtual machines, makes it adaptable to solutions of varying sizes.
Extreme data compression minimizes required storage in cloud environments like Blob Storage.

CONS

Setup is not straightforward, requiring support from Quest engineers and developers, especially during initial testing and configuration in an S3-compatible situation.
Air Gap feature is needed to prevent viruses from attaching when not backing up, keeping QoreStor offline.
Maximum capacity needs to be increased.
Installation is touchy, requiring support connectivity, as it is not user-installable.
Exporting configuration settings would be beneficial to aid in reinstallation and configuration after setup.

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.

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.

It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes.

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.

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.
