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

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"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 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."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"VM backup is much faster and more reliable, as I can test my backups with Data Copy Access jobs."
"It is an easy system to use, and the support, if needed, is always willing to help."
"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."
"Reliable DR Backup/archive to multiple locations Excellent support"
"What I found most valuable in Unitrends is its simple user interface. It also works reliably."
"The ability to backup both physical and virtual machines, along with having an appliance store the backups locally instead of on a file server, NAS, or SAN."
"It works as expected the vast majority of the time, which is an improvement over other products that seem to break with the slightest change in the environment."
"If you are a large organization or corporation, with multiple sites, you can replicate the data from one Unitrends device to another Unitrends appliance, then this is definitely a solution for you."
 

Cons

"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 air gap feature is something I'd really like to see in QoreStor."
"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."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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 setup of the software is definitely not the easiest thing in the world."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"The ransomware protection of QoreStor could use improvement."
"I would like to see more storage options for the free version."
"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."
"Unitrends can be challenging to scale."
"Network-based storage stability could be improved."
"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."
"Every few years, an update may not be applied right and we may have to manually reload the software."
"We had an issue about a year ago, but it actually ended up wiping our entire backup history, because one of the databases got corrupted, and we couldn't recover the backup data."
"The only area that I would say needs some improvements is the initial setup."
 

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."
"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."
"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."
"Unitrends is an expensive solution."
"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."
"No comment."
"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."
"Pricing model constantly changes."
"Initial pricing is competitive. Renewal pricing is steep, so make sure to project costs for the lifetime of the appliance(s)."
"The cost of Unitrends definitely draws you in. The licensing is all included in the appliance, which is a great incentive."
"Talk with the sales guys. They can work with you on the best package."
