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

"If you have VMs to backup, Altaro is the BEST solution for us and many others alike."
"Altaro Hyper-V backup is a product that, once installed, does not need much maintenance."
"The intuitive interface allows you to set up and perform backups and restores easily."
"Give it a try as it's very easy to setup and works like charm."
"The initial setup was simple and easy. Anyone without prior experience can install, configure, and use it."
"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."
"The ability to test the backups without having to manually mount the VHDs after restore allows us to check the integrity of the backups."
"The initial setup was very straightforward, as the software installs easily, is very easy to configure and has a nice GUI."
"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."
"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."
"Quest QoreStor definitely saved us money."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"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."
 

Cons

"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."
"I did not manage to import my old configuration, in v4, into v5 just after it what was released, however, I believe this functionality has been improved."
"Basically, how it works is that you have a single local drive, and then you have a cloud backup. It'd be nice if you could rotate the single local backup drive. As of now, you can't."
"Stability."
"The yearly maintenance fee can be improved. It is high."
"Migrating the physical through a backup and restore to a virtual environment would be very helpful."
"Missing features at the moment are Linux file-level restore, backup from physical machines, German localized version, and probably full tape support (RDX is supported but there is no "real tape" support)."
"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."
"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."
"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."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The air gap feature is something I'd really like to see in QoreStor."
"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 ransomware protection of QoreStor could use improvement."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
 

Pricing and Cost Advice

"​By implementing the solution at multiple locations, significant cost savings were achieved."
"There is a free version for Hosts with 2 VMs."
"VMware is a little pricey, but it is a good solution and priced similar to other products."
"The pricing is okay,"
"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."
"Its yearly maintenance fee is fairly high for me to renew for upgrades and support."
"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."
"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."
"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."
