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

"Great backup features for all my Hyper V machines."
"I could create VM backups from live machines without any issues."
"Generally, the entire program is brilliant, and there isn't any one feature that I can pick out."
"Altaro Hyper-V backup is a product that, once installed, does not need much maintenance."
"Altaro VM Backup is affordably priced, is a best value for its price, and has almost every feature that an expensive, popular product offers."
"I find the solution to be user-friendly and easy to manage and deploy."
"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 CDP backup feature is very nice, as it allows you to take backups at high frequencies and with application consistency."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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 features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."
"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."
 

Cons

"The yearly maintenance fee can be improved. It is high."
"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."
"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."
"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."
"Stability."
"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."
"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."
"To improve Altaro, I would like to see the ability to choose more than one backup location at a time."
"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."
"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 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 management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"The ransomware protection of QoreStor could use improvement."
"The air gap feature is something I'd really like to see in QoreStor."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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."
 

Pricing and Cost Advice

"VMware is a little pricey, but it is a good solution and priced similar to other products."
"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."
"Altaro had the best prices and ROI in the whole bunch that we evaluated."
"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."
"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."
"No other product offers these features for this price. The ROI is great."
"There is a free version for Hosts with 2 VMs."
"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."
"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."
