Cloud Station Server

Cloud Station is a file sharing service that allows you to synchronize files between a centralized Synology Router and multiple client computers and mobile devices. To seamlessly sync your data among these devices, a Synology Router has to be chosen as the host server, and the rest of the paired computers and mobile devices will act as the client devices. Before syncing files with client devices, the Cloud Station Server package needs to be installed on the host server, while a client utility needs to be installed on each of the client device you want to sync with.

Note:

Enable Cloud Station Server

Once Cloud Station Server is enabled, (and if you have enabled the QuickConnect service), you can see your QuickConnect ID on the overview page. Client computers, Synology NAS devices and mobile devices can use this information for creating connections.

To enable shared folder syncing feature:

  1. Use the search field at the top-right corner of Cloud Station Server to find shared folders.
  2. Select the folder you want to enable, and then click Enable.

Note:

Manage Historical Versions of Shared Folders

Cloud Station Server saves historical versions of each modified file. Every time you modify a file, a backup version is created, just in case you make mistakes or wish to revert to an older version.

  1. Go to Settings > Sync Settings.
  2. Select the shared folder for which you want to edit historical versions and click Versioning.
  3. Enter a value between 0 and 32 in the Maximum Versions field.
  4. Select a Rotation Policy.

Cloud Station Server allows admin users to configure different Sync profiles for each user, and use this function to further refine user privileges.

To manage detailed sync behaviors and privileges:

  1. Go to the User Sync Profiles tab and click Create.
  2. In the File Filter tab, give your sync profile a name and specify the file sizes and types you don't want to sync.
  3. Go to the Applied User tab and tick the box next to the users you want to add to your sync profile.

  3. Click Apply to save your settings.

For Advanced Users

If you would like to know more about the way Cloud Station Server works to keep your data safe and synced, please see Synology Cloud Station White Paper.

Storage space utilization:

Cloud Station Server keeps historical versions of every change in your Cloud Station folder. If you conduct a bad modification, or if the file has been damaged or deleted by accident, you can easily restore the file to an older version. However, it requires at least one full copy of any given file as the base version for file history, so the selected shared folders will need doubled disk space. Only the differential data will be kept among different historical file versions.

Note:

What properties are actually synchronized?

Platform File data Mac extended attributes Execution bit Last modified time
Windows - -
Mac OSX
Linux -
iOS (DS cloud) - -
Android (DS cloud) - - -

Default action for file conflicts:

If two users change the same file at the same time, Cloud Station Server will compare last modified time of the two clients and retain the newest version.
