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.

Daily recovery tests have validated restore readiness and ensured consistent data protection
The best features of Unitrends include the daily reporting functionality. When backups fail, it is obvious in the logs what caused the issue. Most times it is a credential problem, which is relatively easy to resolve. Though I have experienced a few more challenging issues, nothing has affected critical backup restore functionality. Every time I have needed to restore something, it has worked successfully. The support team is readily available when I need assistance, and they help walk me through issues, solving them within a reasonable timeframe. The automated backup scheduling feature has helped our organization in managing backup timelines and consistency by handling all the work automatically. We set the schedule, breaking things into smaller chunks since our main common area for files is large. I have staggered the backups so some areas receive more attention than others, particularly for less active data. Adding, removing, excluding, and inputting elements is straightforward. The system makes it simple to schedule portions and generate reports on their functionality. The impact of Unitrends' instant recovery features on strengthening data security measures is significant. I generally use instant recovery when restoring specific files or instances where we need data that has changed. The process involves loading the backup, selecting the desired version, waiting for it to unpack, and retrieving the file. Every restore attempt has been successful. I run instant recovery daily in test mode on two virtual machines. I use it to test my domain controller and file server to ensure they communicate properly in the test environment. This ensures that in case of failure, I can activate the recovery and restore server functionality.

Quotes from Members

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

Pros

"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"Quest QoreStor definitely saved us money."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"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."
"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."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"Quest QoreStor is very stable compared to our previous solution."
"I am impressed with the tool's reporting and UniView features."
"The predictive analytics are great and the reporting is awesome."
"For what it's designed for, I will rate this product a nine and a half out of ten."
"Unitrends product paid for itself in one year."
"If you are a large organization, this is a product for you."
"It has reduced recovery time, from recovering VMs to just simple file-level recovery, and it's all fast and easy."
"With all these new features and (performance) improvements as well as the fusion between two great companies (Unitrends and PHD Virtual), and their products, UEB 7.5 is a feature rich product which I can easily promote to all my customers."
"Customer Service: Awesome support. Technical Support: Awesome support."
 

Cons

"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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 setup of the software is definitely not the easiest thing in the world."
"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."
"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."
"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 solution’s support and onboarding process needs to be improved."
"Making the seeding process more accessible and easier to understand. Also, make more of the undocumented best practices easier to find."
"We have a huge VMware infrastructure with multiple hosts that use local storage. Backup jobs of VMs seem to target one host at a time, so if there are 10 VMs on that host getting backed up, it hammers that ESXi host until sometimes the jobs hang and nothing more occurs."
"​​Follow up for the DRaaS service setup. I'm still waiting to schedule a DRaaS test after upgrading several months ago."
"I would like to see the improve High availability features like switchover and switchback process. also unitrends boomerang compatibilities."
"The ransomware detection from the appliance incorrectly identifies one of my machines as infected with ransomware."
"Stabilizing SQL database backups: They are way too sensitive and I am having to constantly fix SQL level backups."
"It could be a little more customizable."
 

Pricing and Cost Advice

"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
"I would rate the solution's pricing a four out of ten. The licensing is yearly and it depends on the customers."
"You should be aware how much the monthly costs are to use, what the initial costs for hardware are, and what the options to expand are, if needed."
"Pricing model constantly changes."
"Their licensing depended on the number of CPUs you had."
"No comment."
"We found that the cost of Unitrends was about the same as the Dell DR6300. We liked the fact that the Unitrends appliance was all-in-one."
"Talk with the sales guys. They can work with you on the best package."
"When we renew the Unitrends maintenance contract and update it to the latest version, the cost would be $5,000 per year. There are no hidden costs. They've been transparent with the costs."
