Jeff Manuszak

CTO at EDSI

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.

Director Of Information Technology at Creation Technologies

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

"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 integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."

"Quest QoreStor definitely saved us money."

"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."

"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 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."

"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."

More QoreStor pros

"It is fairly stable."

"VM backup is much faster and more reliable, as I can test my backups with Data Copy Access jobs."

"The most valuable feature of Unitrends for me is the automated feedback"

"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."

"The ability to diversify jobs within the same server helps break down a large chunk of data into more manageable and concentrated chunks."

"It is an easy system to use. The support, if needed, is always willing to help."

"It is a quick and easy way to organize my backups and to keep track of them."

"Iinstant recovery (allows a spin-up of your image as a VM on the appliance)."

More Unitrends pros

Cons

"The ransomware protection of QoreStor could use improvement."

"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 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."

"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."

"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 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. 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."

"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."

More QoreStor cons

"Probably the biggest issue I've had is actually paying for the unit, and part of that problem is that they use a third party for the billing."

"The solution’s UI can be improved. I am saying this because I have seen solutions with better UIs."

"Network-based storage stability could be improved."

"I would like to see more storage options for the free version."

"Making the seeding process more accessible and easier to understand. Also, make more of the undocumented best practices easier to find."

"It would be great to have the job throttle/limit the max number of backups on a single ESXi host."

"Follow up for the DRaaS service setup. I'm still waiting to schedule a DRaaS test after upgrading several months ago."

"The solution's base operating system needs to be improved."

More Unitrends cons

Pricing and Cost Advice

"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 cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."

"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."

"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."

"Pricing model constantly changes."

"No comment."

"Their licensing depended on the number of CPUs you had."

"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."

"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."

"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."
