Sync Shared Folder Contents between DiskStations
Shared Folder Sync allows you to sync shared folder contents from a source DiskStation (or "client") to a
destination DiskStation (or "server") over the network.
Enable Shared Folder Sync Service
Before performing Shared Folder Sync, you will need to enable the Shared Folder Sync service on the server
(destination DiskStation).
To enable Shared Folder Sync service on the server:
1 On the server (destination DiskStation), log in to DSM with the credentials of admin or a user belonging to the
administrators group.
2 Go to Main Menu > Control Panel > Network Backup. Make sure Enable network backup service is ticked
and Use customized rsync configuration is deselected to make the target DiskStation available for syncing.
3 Under the Shared Folder Sync tab, tick Enable Shared Folder Sync service.
4 Click Apply.
Link or Unlink the Server and the Client
Follow the instructions below to pair or unpair the server and the client. Shared Folder Sync provides Multiple-
Source Shared Folder Sync feature, which allows multiple clients to sync their shared folders to one DiskStation.
To link the server with a client:
On a client (source DiskStation), perform Shared Folder Sync and choose the server as sync destination. After
the linking process is complete, you can see the linking status in the Info section.
Note: See "Manage Sync Tasks" for more information about how to perform Shared Folder Sync to a server.
To unlink a server from a client:
1 On the server (destination DiskStation), log in to DSM with the credentials of admin or a user belonging to the
administrators group.
2 Go to Main Menu > Control Panel > Network Backup > Shared Folder Sync.
3 Click Connection List, select a connection, and click Unlink.
Manage Sync Tasks
After Shared Folder Sync service is enabled on the server (destination DiskStation), you can log in to a client
(source DiskStation) to perform Shared Folder Sync with the server.
To create a sync task:
1 On the client (source DiskStation), log in to DSM with the credentials of admin or a user belonging to the
administrators group.
