AG
Technical Lead at a manufacturing company with 10,001+ employees
Provides a short-term backup, archive, and cataloging for 20,000 people in our organization
The backup for a large amount of data is slow. When there's a large amount of data, sometimes the backup isn't completed in time. I have a 24 hour cycle, so it doesn't get completed in 24 hours with the large amount of data. With Veritas NetBackup, I can take 20 terabytes of backup in a day.
MW
Works at a financial services firm with 11-50 employees
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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is the incremental backup."
"The command-line interface is good."
"I will highly recommend this product for excellent and quick backup solution in small and large IBM I Series environment."
"In terms of stability, I've found it to be very stable. I've walked into the server room when it was at 60 degrees Celcius, and it was still running fine."
"If you are looking for a reliable and scalable enterprise-class solution, you should consider this solution."
"In terms of stability, I've found it to be very stable."
"The cataloging is the best feature, as it takes millions of frames for the backup and, because it's incremental, it takes less time to complete."
"Overall IBM ProtectTIER is a great solution. It is easy to use."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"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."
"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."
"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."
"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."
 

Cons

"Setting up the system to work with legacy equipment is a bit complex at times."
"I would like the possibility to back up the infrastructure and then replicate it upon on restart, without having to orchestrate the starting of the VM."
"These days, we are thinking about pushing another solution because of the poor support from IBM."
"The backup for a large amount of data is slow. When there's a large amount of data, sometimes the backup isn't completed in time."
"It is unmanageable. Support would be good."
"My advice to anybody who is considering this solution is to conduct a proof of concept first because everybody's needs are different, and this product is not suitable for every kind of backup."
"IBM ProtectTIER could improve by being more user-friendly."
"The configuration wizards are still complex and hard to navigate. These should be easier to manage."
"The setup of the software is definitely not the easiest thing in the world."
"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."
"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."
"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."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
 

Pricing and Cost Advice

"We have a capacity-based license, which is managed centrally for all the sites of my company."
"The customer can decide how they want to purchase a license. However, the price of the solution is expensive."
"IBM ProtectTIER is an expensive solution."
"This solution is very expensive."
"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 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."
