Multi-thread backups and snapshotting have eliminated the scheduling issues we had to deal with around backups

What is our primary use case?

The solution is the means for taking our NetVault backups and handing them off to QoreStor for all the dedupe and compression. We keep them temporarily on disk for a short period of time, like a week or two, but then we start replicating up into the cloud, within six hours of backup. In summary, we use it primarily for backup and restore. We're currently on-premises. We're a pretty small organization, but we have a cabinet in a co-location facility and we have QoreStor there, in our infrastructure. It's a virtual infrastructure but we control it.

Pros and Cons

  • "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 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."

What other advice do I have?

If you're in a situation where you're still using tape, at a minimum, this is worth investigating. For me, the biggest lesson was the exposure it gave me to the cloud environment. Prior to using this, I had heard people talk about AWS, and I had heard semi horror stories about how you never know what it's going to cost you if you get involved in that environment. We worked with our local co-location company and they had built out their own cloud environment. So it was a really good opportunity for me to dip my toes in cloud. From what I can tell, Quest is clearer about what your costs are…

The deduplication saves us a lot of space and reduces network traffic

What is our primary use case?

We presented QoreStor to NetVault, the backup software. We have two QoreStors, one on the main site, and then another one on the remote site. They are a primary backup and a secondary backup target.

Pros and Cons

  • "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."
  • "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."

What other advice do I have?

It's a good product. QoreStor has a lot of features that I don't know about. It would be nice to take advantage of these features by getting updates from them that these features exist. I would rate it a nine out of ten.
