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…

Cost savings and efficient data management improve operations but support quality varies
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. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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 intuitive interface allows you to set up and perform backups and restores easily."
"Ability to restore to any host."
"The initial setup was simple and easy. Anyone without prior experience can install, configure, and use it."
"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."
"The CDP backup feature is very nice, as it allows you to take backups at high frequencies and with application consistency."
"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."
"It is an excellent product. It is easy to deploy, stable, and fast. Their support is excellent."
"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 definitely saved us money."
"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."
"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."
"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."
"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."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
 

Cons

"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."
"Backup speed and comparisons between versions used to be slow on big VMs but that was improved greatly later on."
"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."
"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."
"Migrating the physical through a backup and restore to a virtual environment would be very helpful."
"It would be nice to be able to recover the items to their original location."
"The cloud backup and VMware support (now available in the latest releases), could do with some improvement."
"The scalability of the solution is limited."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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."
"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 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."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
 

Pricing and Cost Advice

"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 pricing is okay,"
"The price is great for the utility you get and the licensing has never caused any issues with my company."
"No other product offers these features for this price. The ROI is great."
"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."
"​By implementing the solution at multiple locations, significant cost savings were achieved."
"VMware is a little pricey, but it is a good solution and priced similar to other products."
"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 cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
