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.

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

"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."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"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."
"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."
"It is an all-inclusive backup appliance that is separate from other storage needed to backup and has the ability to backup both virtual and physical nodes."
"The ability to diversify jobs within the same server helps break down a large chunk of data into more manageable and concentrated chunks."
"VM backup is much faster and more reliable, as I can test my backups with Data Copy Access jobs."
"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."
"Unitrends product paid for itself in one year."
"Being an appliance-based solution, we were able to migrate backup solutions without having to purchase a lot of hardware separately."
"It's not easy to scale it."
"For what it's designed for, I will rate this product a nine and a half out of ten."
 

Cons

"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."
"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."
"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."
"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."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something."
"The ransomware protection of QoreStor could use improvement."
"Scalability is where I'm running into more of an issue right now. To upgrade is pretty expensive; it's not like you can just buy a smaller appliance and put it with the one you already have, you need to buy a larger appliance and that can get fairly pricey."
"The ability to run just differentials without pulling the full on your archive."
"Though this is kinda hard to come up with at this point, but I think instead of deploying the VBAs from vCenter, it would be really nice if only the first deployment is needed from vCenter and the rest could be handled from within the solutions portal."
"The ransomware detection from the appliance incorrectly identifies one of my machines as infected with ransomware."
"I would like to see more storage options for the free version."
"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."
"For smaller K12 schools, I wish they offered a beefier free version with more storage and options."
"It seems like Unitrends moved away from enterprise customer engagement and moved more towards the managed service provider market."
 

Pricing and Cost Advice

"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."
"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 of Unitrends definitely draws you in. The licensing is all included in the appliance, which is a great incentive."
"I would rate the solution's pricing a four out of ten. The licensing is yearly and it depends on the customers."
"Pricing model constantly changes."
"Talk with the sales guys. They can work with you on the best package."
"Initial pricing is competitive. Renewal pricing is steep, so make sure to project costs for the lifetime of the appliance(s)."
"With respect to cost, my advice is to get what you need."
"When you purchase initially, get into the program which gives replacement hardware for free when you renew your support agreement."
"Based on a scale of one to ten, with one being low and ten being high, I would rate the pricing of this solution as a three. Also, there are no additional costs involved in the standard licensing of the solution."
