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.

Reliable and cost-effective

One area where Synology DSM could improve is in enhancing its ability to detect and respond to security threats during backups and replication. Currently, it lacks the capability to automatically stop backups if it detects a virus or suspicious network activity, as some third-party solutions can. Having AI-driven analytics to identify anomalies and halt backups during potential attacks, along with notifications to administrators, would be valuable. Additionally, providing a dashboard for monitoring the backup environment's security would be a beneficial feature. These improvements would help address security concerns and make Synology more competitive in this aspect.

Quotes from Members

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

Pros

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

"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."

"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."

"Quest QoreStor is very stable compared to our previous solution."

"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 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

"It offers a variety of software options through its package center, allowing users to customize their NAS device to serve multiple purposes."

"Synology DSM is very easy to work and operate."

"The most valuable aspect is its ability to handle multiple disks."

"The solution's most valuable feature stems from its ease of use, making it the tool's most interesting part."

"Because of its simplicity and the wide array of features it offers, I would recommend DSM for both tech-savvy individuals and those who prefer a straightforward file-serving solution."

"The most valuable features are the basic storage, file management, Btrfs file system, and built-in backups that come with the solution."

"The most valuable feature of the solution is that it serves as a backup for our company's virtual machine."

"The most valuable features of Synology DSM are its security and connectivity."

More Synology DSM pros

Cons

"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."

"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."

"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 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 need to increase their maximum capacity. Other than that, they're doing a pretty good job."

"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."

"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."

More QoreStor cons

"Even though Synology provides a backup solution, it does not recognize the VM movement across cluster hosts."

"One area where Synology DSM could improve is in enhancing its ability to detect and respond to security threats during backups and replication."

"Users may lose their data if they don't configure the solution properly."

"The product's only shortcoming is pricing, as it is an expensive solution."

"Synology DSM is a good enough solution for small and medium companies, but I have not seen a big configuration of the solution for a big organization."

"Synology DSM's user interface is not quite intuitive."

"There's a surveillance application that allows you to connect IP cameras and stream footage to Synology and it is a great feature, but it's not always clear that adding more cameras may require purchasing additional licenses."

"The only bothersome aspect is that the device is aging."

More Synology DSM cons

Pricing and Cost Advice

"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."

"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 price of the solution is very good."

"Synology DSM is a free tool."

"Synology DSM is a cheap solution."

"The licensing part of the solution is free. The hardware is more expensive than the other solutions in the market, but it's okay in the long run."

"It is quite an affordable solution."

"The pricing varies widely, catering to a broad range of needs."

"The solution’s pricing is neither cheap nor expensive."
