Expert Backup at a tech services company with 201-500 employees
A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments
Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

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

"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."
"I am impressed with the tool's technical alliance with Veeam and Veritas."
"The most valuable aspect is its ability to handle multiple disks."
"It offers a variety of software options through its package center, allowing users to customize their NAS device to serve multiple purposes."
"The most valuable features of Synology DSM are its security and connectivity."
"The most valuable feature of the solution is that it serves as a backup for our company's virtual machine."
"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."
"The most valuable features are the basic storage, file management, Btrfs file system, and built-in backups that come with the solution."
"The product performs well. It is easy to use and implement."
 

Cons

"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."
"The product needs to improve performance while scaling out. It also needs to improve stability."
"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."
"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."
"Users may lose their data if they don't configure the solution properly."
"One area where Synology DSM could improve is in enhancing its ability to detect and respond to security threats during backups and replication."
"The platform could be much more cost-effective and flexible for integrating third-party products."
"Synology DSM's user interface is not quite intuitive."
"The only bothersome aspect is that the device is aging."
"The product's only shortcoming is pricing, as it is an expensive solution."
 

Pricing and Cost Advice

"Synology DSM is a free tool."
"It is quite an affordable solution."
"The pricing varies widely, catering to a broad range of needs."
"The price of the solution is very good."
"Synology DSM is a cheap solution."
