Download Synology DSM 6.0 build 7307 RC

Synology has now released the release candidate of version 6.0 of Disk Station Manager after two beta releases. Synology DSM is the management software that runs on several of the company’s NAS products. The Disk, Cube and Rack Stations offer more than just extra storage space. For example, backups of all clients on the network can be made and files can be downloaded via http, ftp, bittorrent, usenet and emule, so that, for example, energy-hungry PCs can switch off at night while the download just comes in. In addition, audio and video files can be streamed over the network via the built-in iTunes server, a dynamic website can be hosted using PHP and MySQL and the device can act as a print server.

To be able to install version 6.0, at least version 5.2 must be present. Furthermore, it is only suitable for the NAS models whose type number ends with 11 or higher. For the other conditions and the different downloads, look at this page. In version 6.0 we find improvements in Cloud, Note, Photo and Video Station, there is a collaboration drive for spreadsheets and the possibilities for backup and restore have been improved. Also, DSM is now fully 64-bit and therefore performance improvements can be observed. In addition, there are several new features for high-performance models, including support for the btrfsfile system, a comprehensive webmail client and email server, a Load Balancer, a Document Viewer, and Docker support has also been improved. The changelog for this release candidate further shows the following improvements:

Btrfs File System

• Set usage/user quota for shared folders.
• Enable file compression to increase the flexibility of volume usage.
• Perform defragmentation to increase system performance.
• Data checksum is enabled by default and data scrubbing can be run to verify data integrity.
• When file versioning is enabled in Cloud Station Server, it will not occupy additional storage on Btrfs file system. On other file systems, file versioning will occupy additional space equal to the size of each shared folder.
• Files will be backed up once the backup task is started, even if the files are changed or deleted afterwards.
• Converting existing ext4 file system to Btrfs is not supported. To store files under Btrfs file system you must create a new folder.
• Available on the following models:
  • 16 series: RS2416RP+, RS2416+, RS18016xs+, DS716+, DS216+
  • 15 Series: RC18015xs+, RS815RP+, RS815+, DS3615xs, DS2415+, DS1815+, DS1515+, DS415+
