Drive and Photo Service:Sync backup (public preview)

Bidirectional synchronization and one-way upload

You can perform bidirectional synchronization or one-way upload for folders in Team space, personal space, and received shares.

Advanced settings

Bidirectional synchronization

• In bidirectional synchronization mode, the local and cloud directories remain identical. File operations in one location are mirrored in the other. However, the deletion behavior differs:

  • If you delete a file locally, the corresponding file in the cloud is moved to the recycle bin.

  • If you delete a file in the cloud, the local file is moved to the recycle bin on Windows. On macOS, the file is deleted permanently, as moving it to the trash is not currently supported.

One-way upload

• In one-way upload mode, the client backs up the local directory to the cloud. File operations in the cloud do not affect local files. This mode is primarily used for backup.

  • The following table describes the cloud behavior when you perform file operations locally.

    Local file operation	Cloud behavior
    Create file	Creates a file
    Delete a file or move it to the recycle bin	No action by default. (If you enable the deletion setting, the cloud file is moved to the recycle bin.)
    Move file	Moves a file. (Due to operating system limitations, moving a file may sometimes result in a copy operation where the original file is not deleted. A similar issue can occur when renaming a file.)
    Rename file	Renames a file
    Modify file content	Creates a new version
    Copy file	Creates a new file

  • The following table describes the local behavior when you perform file operations in the cloud.

    Cloud file operation	Local behavior
    Create file	No action
    Delete a file or move it to the recycle bin	If the file was originally uploaded from the local device: The local device re-uploads the original file to the cloud. (To delete a locally backed-up file from the cloud, you must first enable the deletion setting and then delete the corresponding local file. The cloud file will then be moved to the recycle bin automatically.) If the file was not uploaded from the local device: No action.
    Move file
    Rename file
    Modify file content	No action. (If a locally backed-up file is modified in the cloud, the previously backed-up version is stored as a history version. However, due to version limits and automatic merge policies, this history version may be purged. You should configure appropriate version policies or avoid editing backed-up files directly in the cloud.)
    Copy file	No action

Synchronizer permission

• Users with the Synchronizer permission can perform bidirectional synchronization or one-way upload for folders in team space and received shares.

Backer permission

• Users with the Backer permission can perform one-way upload for folders in team space and received shares.

Users without synchronizer or backer permissions

• Users without Backer or Synchronizer permissions can synchronize or upload folders only in their personal space and received transfers.

Sync backup

• On the sync backup page, click Create sync backup to start the configuration.

Create sync backup

• In the Create sync backup dialog box, fill in the required fields: Select local disk/folder and Select cloud folder. Select a Sync Type (the default is "bidirectional synchronization").

• In the advanced settings dialog box, you can configure sync filtering, sync rate limits, the handling of local file deletion in one-way upload mode, and whether to enable automatic synchronization.

Sync details

• Sync details show statuses such as "sync completed", "syncing", and "sync error".

• You can sort sync tasks by "Cloud Name" or "Creation Time".

• You can filter sync tasks by "Sync Status", "Sync Type", or "Sync Space".

• Task management options include pausing or canceling a sync task, changing its settings, viewing its details, and locating the synchronized files locally or in the cloud.
