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

"Hornetsecurity Altaro VM Backup's most valuable features include its user-friendly interface and the ability to perform data compression updates, which enhance overall efficiency and effectiveness."
"Altaro Hyper-V backup is a product that, once installed, does not need much maintenance."
"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."
"It is an excellent product; it is easy to deploy, stable, and fast, and their support is excellent."
"Altaro reduced the time we needed for managing our backups, especially significant is the Cloud Management Console, which solved many issues we had with prior products."
"The intuitive interface allows you to set up and perform backups and restores easily."
"DR time has been massively reduced."
"Excellent compression and deduplication with off-site WAN backup included."
"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."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"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."
"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."
"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."
"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."
"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 only issue at the moment is a lack of throttling."
"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)."
"The software does have occasional problems with shadow copy but restarting the services rectifies this."
"Being able to backup the actual host machine would be an improvement for us."
"However it has No support for Tape Drive backup – So no Disk-to-tape backup is possible."
"The cloud backup and VMware support (now available in the latest releases), could do with some improvement."
"The initial set up was complex, and I was not able to do the set up myself."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The ransomware protection of QoreStor could use improvement."
"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."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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 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

"Its yearly maintenance fee is fairly high for me to renew for upgrades and support."
"No other product offers these features for this price. The ROI is great."
"The price is great for the utility you get and the licensing has never caused any issues with my company."
"VMware is a little pricey, but it is a good solution and priced similar to other products."
"The pricing is okay,"
"Altaro had the best prices and ROI in the whole bunch that we evaluated."
"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."
"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."
"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
