Asif Usmani - PeerSpot reviewer
Regional Sales Manager at S2
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-efficient, highly scalable, and installable on different types of hardware
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. We are pretty lenient as we do a lot of IT support ourselves. We are not very hard on support organizations, but when a customer has a support issue, it would be easier if the support processes were a little bit more automated. It would be beneficial to have an easier way to upload diagnostic dump files. They can make it easy for the customer to collect the diagnostic data. 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. This is especially critical because it stores customers' backups, and a failure can have significant business impacts. If a customer does not have the backups and has a disaster, they can be out of business, so monitoring is key.

Quotes from Members

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

Pros

"It is an excellent product; it is easy to deploy, stable, and fast, and their support is excellent."
"The product has many valuable features for handling backup needs, including replication, live migration, and incremental disaster recovery."
"This product is not expensive, does the job what I bought it for, and is not time consuming."
"All of the features are fantastic and also the management from Microsoft dealing with multiple machines is great. The whole package is excellent for me."
"I could create VM backups from live machines without any issues."
"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."
"Great backup features for all my Hyper V machines."
"All of the features are fantastic and also the management from Microsoft dealing with multiple machines is great."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"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."
"I would rate QoreStor a ten out of ten for what it offers for the price."
 

Cons

"We use Linux guests on Hyper-V clusters and we really need the file level restore on these VMs (ext3 and 4 file systems) functionality."
"The solution needs multi-platform support as it is currently only available for VMware and Hyper-V."
"Sometimes, due to disk space and VSS, we have experienced stability issues."
"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."
"Storage usage: you have often to manually free disk spaces."
"The replication time between virtual machines is slow."
"It would be good to if they would expand the functionality to be able to backup normal servers without Hyper-V."
"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."
"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."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something."
"They need to increase their maximum capacity."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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."
 

Pricing and Cost Advice

"Its yearly maintenance fee is fairly high for me to renew for upgrades and support."
"Altaro had the best prices and ROI in the whole bunch that we evaluated."
"​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."
"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."
"No other product offers these features for this price. The ROI is great."
"The pricing is okay,"
"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."
