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

"In terms of stability, I've found it to be very stable."
"The most valuable features are the self-service features and the ability to search the data."
"If you are looking for a reliable and scalable enterprise-class solution, you should consider this solution."
"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."
"The command-line interface is good."
"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."
"Overall IBM ProtectTIER is a great solution. It is easy to use."
"I will highly recommend this product for excellent and quick backup solution in small and large IBM I Series environment."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"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."
"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 to reduce our backup storage requirements on-premise by at least 90%."
 

Cons

"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."
"The configuration wizards are still complex and hard to navigate. These should be easier to manage."
"These days, we are thinking about pushing another solution because of the poor support from IBM."
"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."
"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."
"Setting up the system to work with legacy equipment is a bit complex at times."
"IBM ProtectTIER could improve by being more user-friendly."
"The air gap feature is something I'd really like to see in QoreStor."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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."
"The setup of the software is definitely not the easiest thing in the world."
 

Pricing and Cost Advice

"IBM ProtectTIER is an expensive solution."
"We have a capacity-based license, which is managed centrally for all the sites of my company."
"This solution is very expensive."
"The customer can decide how they want to purchase a license. However, the price of the solution is 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 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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
