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

"The ease of use of the solution is its most valuable feature. The interface is also excellent."
"The initial setup was very straightforward, as the software installs easily, is very easy to configure and has a nice GUI."
"We use the latest feature in Altaro called CDP (Continuous Data Protection) to back up our VMs as often as every five minutes. It allows us to make sure no data is accidentally deleted or overwritten."
"Great backup features for all my Hyper V machines."
"If you have VMs to backup, Altaro is the BEST solution for us and many others alike."
"Altaro Hyper-v backup is not pricey and provides great features to secure your production data on Microsoft Hyper-V clusters."
"There is a free version for Hosts with 2 VMs."
"Reverse Delta is Altaro proprietary backup deduplication technology. With Reverse Delta, the latest version of a file is always made available in its entirety, not as a delta file."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"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."
"Quest QoreStor definitely saved us money."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"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."
"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."
"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."
 

Cons

"The initial set up was complex, and I was not able to do the set up myself."
"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."
"Replication is not fast, the GUI could be more user-friendly, and technical support is lacking in Iran."
"Hornetsecurity Altaro VM Backup could be improved in several areas, such as enhancing scalability features and possibly reducing the price."
"The software does have occasional problems with shadow copy but restarting the services rectifies this."
"The yearly maintenance fee can be improved. It is high."
"The recovery speed could be quicker, especially when you only need a file or two."
"I need to be able to restore emails to Exchange Live not just to a PST. This is a major drawback as I want to be able to restore individual items or mailboxes directly into my live Exchange databases so the user can see the email right away."
"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."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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 air gap feature is something I'd really like to see in QoreStor."
"The ransomware protection of QoreStor could use improvement."
"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 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."
 

Pricing and Cost Advice

"No other product offers these features for this price. The ROI is great."
"Its yearly maintenance fee is fairly high for me to renew for upgrades and support."
"The price is great for the utility you get and the licensing has never caused any issues with my company."
"The pricing is okay,"
"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."
"​By implementing the solution at multiple locations, significant cost savings were achieved."
"There is a free version for Hosts with 2 VMs."
"Altaro had the best prices and ROI in the whole bunch that we evaluated."
"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."
"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."
