Cloud Sync

With Cloud Sync, you can seamlessly sync and share files among your DiskStation and multiple public cloud services, such as Dropbox, Baidu Cloud and Google Drive.

Create New Connections

To sync files among your DiskStation and public cloud services, you need to create connections on Cloud Sync to link to the service provider by using your user credentials.

To create a new connection:

  1. On the Cloud Sync user interface, click on the Create icon at the bottom-left corner to start the wizard.
  2. Follow the instructions to choose the public cloud service you want to sync files with, and log in with your user credentials.
  3. Select a local folder as your sync destination to store the files.

Note:

  1. Current supported public clouds include Dropbox, Baidu Cloud and Google Drive.
  2. When creating connections, you can only select empty folders as your sync folders.
  3. Each user credential can only be used for creating one connection. You can create multiple connections all with different user credentials, but not duplicate connections with the same user credential.
  4. Due to Baidu's limitations, you are only allowed to sync files to the "My Application's Data > Cloud Sync" folder in your Baidu Cloud storage.
  5. For files on Google Drive, only those that were uploaded from your local PC to your Google Drive will be synced.
  6. File or folder names that end with a period (.) or a space will be renamed as "file name._DiskStation_modified date_TailCharacterConflict".
