Lacks multi-platform support and physical infrastructure but excels in storage optimization
We use it for VM backup and Office 365 backup I find the solution to be user-friendly and easy to manage and deploy. It provides storage for Office 365, which is beneficial, and the deduplication technology is excellent, especially in optimizing storage capacity compared to others. In terms of…

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

"I could create VM backups from live machines without any issues."
"It is a great lesson in keeping it simple."
"In Hyper-V, I think there are many valuable features, including replication between different hosts, high availability, live migration where I can migrate between one host to another, as well as incremental disaster recovery, which are very good."
"This solution is stable."
"I find the solution to be user-friendly and easy to manage and deploy."
"All of the features are fantastic and also the management from Microsoft dealing with multiple machines is great. The whole package is excellent for me."
"The ability to test the backups without having to manually mount the VHDs after restore allows us to check the integrity of the backups."
"Generally, the entire program is brilliant, and there isn't any one feature that I can pick out."
"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."
"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%."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"Quest QoreStor is very stable compared to our previous solution."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"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."
"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."
 

Cons

"The solution needs multi-platform support as it is currently only available for VMware and Hyper-V. It also lacks support for physical servers and workstations."
"The cloud backup and VMware support (now available in the latest releases), could do with some improvement."
"The only issue at the moment is a lack of throttling."
"Altaro also supports booting directly from a backup drive (image), but this feature is hamstrung by the fact that it requires the backup image to be neither compressed or encrypted."
"Availability of physical server backup would be an added advantage."
"Improvement areas for Altaro VM Backup include enhancing backup and deduplication solutions for continuous operation and offering an all-in-one solution for hardware backup."
"It would be nice to see a feature that backs up the host so that, in case of a server failure, an entire server could be restored all at once."
"The software does have occasional problems with shadow copy but restarting the services rectifies this."
"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."
"The setup of the software 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."
"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 management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
 

Pricing and Cost Advice

"Its yearly maintenance fee is fairly high for me to renew for upgrades and support."
"Altaro VM Backup is affordably priced. It is a best value for its price and has almost every feature that an expensive, popular product offers."
"VMware is a little pricey, but it is a good solution and priced similar to other products."
"There is a free version for two VMs. I would advise to study the deployment environment well, prior to committing to order a license per host."
"The pricing is okay,"
"​By implementing the solution at multiple locations, significant cost savings were achieved."
"The price is great for the utility you get and the licensing has never caused any issues with my company."
"Altaro had the best prices and ROI in the whole bunch that we evaluated."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"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."
