A reliable backup product which needs little management

For most technical users the setup and initial deployment are fairly straightforward and once deployed it 99% of the time looks after itself. Installation of the agents is similar to most other products in that it has an install wizard to guide you, the accompanying documentation is also very useful to assist wherever you are in the agent install and policy setup process. Normally our customers' IT team does the deployment of agents, however, this isn't a daunting task unless you are dealing with multiple servers to protect the product. On a server-by-server basis, the deployment doesn't take long. From the MSP side of things, the infrastructure sitting behind the scenes doesn't take too much to install, configure and maintain.

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.

Quotes from Members

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

Pros

"The solution is very stable."

"The efficiency and convenience are excellent."

"The solution is a free engine to help work with the container."

"The Granular Restore of SQL feature has been a lifesaver more times than I can count. One of the main reasons for looking at Carbonite was their support for platforms like AIX and AS/400 Series."

"It does not slow down your computer or use a lot of resources as it works."

"Technical support handled all our issues quickly and effectively."

"Easy verification of things is the most valuable feature."

"I find the BMR/image and the recovery pieces are valuable."

More Carbonite Server pros

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

"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 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."

"I would rate QoreStor a ten out of ten for what it offers for the price."

"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."

"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."

More QoreStor pros

Cons

"In the next release I would like to see an improvement in the auto failover option."

"They do not yet have USB recovery but they are adding it in coming releases."

"The Hyper-V backup has room for improvement."

"The support for object storage isn't quite there yet. Its public cloud support can be improved. I would love to see the public cloud support for object storage, and it would be great, but what I always hear from the folks at Carbonite is that in a lot of cases, it directly competes with their cloud offering. So, I don't know when or where that will go or if that will go anywhere, but we are hopeful to see something. The dashboard is a little outdated. If they gave it a facelift and put some better design around their dashboard, that would be tremendous. I generally care less about the visual aesthetics of an application as long as it does what it needed to do, which is true in the case of this solution. We also have the Microsoft 365 platform. Because they're two separate platforms, I have to log in to my Microsoft platform to manage it, and I have to log into my Carbonite server backup platform to manage it. Having these two coexist together in one management console is really what we're looking for, but we went for it knowing this. We also knew that there would be some integration coming down the road. So, we're again hoping to see some of that coming in 2021."

"The stability has room for improvement."

"It could be a little bit easier or faster to be able to access data files without having to download anything."

"The only thing that I would like to see improved is related to marketing. Currently, it is very difficult to find the right paper and stuff for me. Their marketing department should provide better information because currently, it is very difficult to find information on the internet. It was bought over by OpenText, and you won't be able to find a lot of information about this solution on their site. They should also provide training facilities for commercial purposes. Some of my colleagues recently went for pilot training, and they were technical. If I want to get trained, the training has to be more commercial. Currently, there is no such training for users like me."

"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."

"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 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."

"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."

"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."

"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."

Pricing and Cost Advice

"The solution is open source."

"The pricing is between $120 and $150 per year."

"Its price is reasonable."

"We pay 9,000 dollars per year for our license."

"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."

"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."
