Featured Reviews

Jeff Manuszak - PeerSpot reviewer
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.
Todd Guthrie - PeerSpot reviewer
The solution can be used to back up servers and Hyper-V cluster nodes, but its support is super expensive
I wouldn't rate Unitrends a ten out of ten because we had some hard drive failures in the appliance. Typically, when you have OneDrive, you can get it replaced. For some particular reason, the situation caused the entire system to crash. We had to reinstall the CentOS operating system on it, and we lost all our backups. They said there was no way to retain it, and it was pretty devastating and concerning that a drive failure would cause the loss of all the data on the appliance. It was extremely disappointing, and we had to start from scratch after three years worth of backup data. I rate Unitrends a nine out of ten for stability.

Quotes from Members

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

Pros

"Quest QoreStor definitely saved us money."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
"Quest QoreStor is very stable compared to our previous solution."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
"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."
"When I have had to use tech support, they've been very good."
"I really like the reporting options you get for various email reports."
"Unitrends has helped us cut down the time that it takes to restore a server to its original configuration."
"It is very easy to set up and get started. Almost too easy. We racked this device and had it up and running in less than 15 minutes."
"Iinstant recovery (allows a spin-up of your image as a VM on the appliance)."
"What I found most valuable in Unitrends is its simple user interface. It also works reliably."
"The simple and fast restore routine."
"Backup/archive to multiple locations."
 

Cons

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"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. 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."
"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."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"It could be a little more customizable."
"Network-based storage stability could be improved."
"There's a lot that can be made better. For example, it could be more scalable."
"The solution’s support and onboarding process needs to be improved."
"The ability to run just differentials without pulling the full on your archive."
"Comparing the features and the working pattern, definitely they have to come down on pricing if they want to compete in the market."
"It seems like Unitrends moved away from enterprise customer engagement and moved more towards the managed service provider market."
"​​Follow up for the DRaaS service setup. I'm still waiting to schedule a DRaaS test after upgrading several months ago."
 

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."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"When you purchase initially, get into the program which gives replacement hardware for free when you renew your support agreement."
"Unitrends is an expensive solution."
"The cost of Unitrends definitely draws you in. The licensing is all included in the appliance, which is a great incentive."
"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."
"I would rate the solution's pricing a four out of ten. The licensing is yearly and it depends on the customers."
"Their licensing depended on the number of CPUs you had."
"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."
