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%."
"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."
"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."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"Unitrends really has cross-compatibility and a broad area of support for various operating system backups."
"I like the fact that you can recover the VMs inside the appliance. For example, they're basically running this appliance on a Linux-based distribution, and they're spinning off KVM virtual machines inside."
"Iinstant recovery (allows a spin-up of your image as a VM on the appliance)."
"Being an appliance-based solution, we were able to migrate backup solutions without having to purchase a lot of hardware separately."
"Easily mastered interface and application for backup/recovery, versatile, works well in VM and physical environments, with nice VM or file-level recovery without spinning anything up to accommodate."
"The backup feature and recovery option are good because they allow the instant recovery of Hyper-V nodes and files."
"The nice thing with this appliance is you do not have to worry about server licencing, and it's separate from the SAN."
"It's not easy to scale it."
 

Cons

"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."
"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."
"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."
"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."
"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 setup of the software is definitely not the easiest thing in the world."
"For smaller K12 schools, I wish they offered a beefier free version with more storage and options."
"The solution's base operating system needs to be improved."
"I wouldn't recommend this product to potential customers because it's an appliance-based model, and you'll be locked in with that vendor."
"I would like to see more storage options for the free version."
"Stabilizing SQL database backups: They are way too sensitive and I am having to constantly fix SQL level backups."
"Technical support has not been very helpful when there are complex issues. It is sometimes difficult to find someone who can answer questions the right way."
"There are a few quirks where the GUI, agent, and back-end are not precisely meshed."
"The amount of updates which are being released. Updates should be limited to two or three a year, focusing more on quality instead of a rushed bug release."
 

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."
"No comment."
"Pricing model constantly changes."
"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."
"Talk with the sales guys. They can work with you on the best package."
"Their licensing depended on the number of CPUs you had."
"Unitrends is an expensive solution."
"When you purchase initially, get into the program which gives replacement hardware for free when you renew your support agreement."
"Make sure you do the homework to size the solution properly. Buy the Enterprise Plus licensing if you can afford it."
