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.

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

"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."

"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."

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

"Quest QoreStor definitely saved us money."

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

"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."

"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."

"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."

More Quest QoreStor pros

"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."

"The product performs well. It is easy to use and implement."

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

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

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

"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."

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

Cons

"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 ransomware protection of QoreStor could use improvement."

"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."

"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."

"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."

"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."

More Quest QoreStor cons

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

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

"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."

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

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

"The platform could be much more cost-effective and flexible for integrating third-party products."

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

More Synology DSM cons

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."

"It is quite an affordable solution."

"Synology DSM is a cheap solution."

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

"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."

"Synology DSM is a free tool."

"The price of the solution is very good."

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