This topic describes the sync backup feature. Sync backup is a convenient and efficient cloud storage feature that supports bidirectional real-time synchronization between cloud and local data, achieving eventual consistency of data across multiple terminal devices.
If you need to use the sync backup feature, be sure to follow these steps:
Confirm that you are using the PC client to log on to the Cloud Drive for Enterprises (CDE) client (version 1.4.0 or above). For the latest version, see Client download.
Confirm that the history version feature is enabled.
Contact us to enable the sync backup feature, with the enterprise code provided.
After the sync backup feature is enabled, if you do not see the sync backup feature entry in the user interface, log on again to check.
This feature is a value-added service. During the public preview period, it is free to use. If charges are introduced later, we will notify you in time.
Feature description
Cloud-end bidirectional synchronization feature: Supports real-time bidirectional synchronization or one-way upload of folders in the team space, personal space, and received shares on the cloud disk with on-premises folders.
Multi-terminal synchronization: Supports automatic synchronization between multiple device terminals and the cloud. Files are updated in real-time, breaking down barriers between devices, allowing access to required files on any device.
Efficient automatic sync backup: The sync disk will automatically back up specified files according to your settings, protecting your data security.
Enabling method
For the first-time use of the sync disk feature, follow the step prompts for installation and other operations. After successful installation, create a sync backup.
Create sync backup
Bidirectional synchronization/one-way upload
Support two-way synchronization or one-way upload for the team space, personal space, and folders within the received shares in the cloud.
Supports bidirectional synchronization or one-way upload of folders in the team space, personal space, and shared space on the cloud.
Advanced settings
Bidirectional synchronization
The file data on both local and cloud are completely consistent. Changes on one end will be synchronized to the other end.
One-way upload
Changes in the on-premises folder will be synchronized to the cloud (except for delete operations), but changes in the cloud files will not affect the local.
The delete rule can be set in Advanced > Other Settings > Delete local files in one-way upload mode.
Sync backup rule description
Bidirectional synchronization
In bidirectional synchronization mode, the local directory will be completely consistent with the cloud. File operations on one end will be reflected on the other end. There are differences when performing delete operations:
When a file is deleted locally, the corresponding file in the cloud will be moved to the recycle bin.
When a file is deleted in the cloud, the Windows system will move the local file to the recycle bin, while the Mac system will directly delete the file (currently does not support moving to the trash).
One-way upload
In one-way upload mode, the local directory will be backed up to the cloud. File operations in the cloud directory will not affect local files. This mode is mainly suitable for backup scenarios.
When different file operations are performed locally, the corresponding behavior in the cloud is as follows:
File operation performed locally
Cloud behavior
Create a file
Create a file
Delete a file/move to recycle bin
No operation by default
(If the deletion configuration is enabled, the cloud file will be moved to the recycle bin)
Move a file
Move a file
(Due to operating system limitations, moving A-->B/A may eventually result in creating A under B in the cloud, with the original A file remaining; the same applies to renaming files)
Rename a file
Rename a file
Modify file content
Create a new version
Copy a file
Create a new file
When different file operations are performed in the cloud, the corresponding behavior locally is as follows:
File operation performed in the cloud
Local behavior
Create a file
No operation
Delete a file/move to recycle bin
If the file is uploaded locally: re-upload the original file to the cloud
(To delete a file backed up locally in the cloud, you need to enable the delete switch first, delete the corresponding local file, and the cloud will automatically move the file to the recycle bin.)
If the file is not uploaded locally: no operation
Move a file
Rename a file
Modify file content
No operation
(If the cloud modifies a file backed up locally, the file version successfully backed up locally will exist in the cloud file history version. However, due to the limitation of the number of history versions and the impact of automatic merge policies, the file version successfully backed up may be cleared. You need to set an appropriate version merge/cleanup policy based on specific usage scenarios or try not to edit files uploaded from local backups in the cloud.)
Copy a file
No operation
Permission description
If you encounter issues during Authorization Management, refer to Permission Description.
Syncer permission description
When a user is granted Synchronizer permission, they can perform bidirectional synchronization or one-way upload operations on folders within team space and received shares.
Backuper permission description
When a user is granted Backer permission, they can perform one-way upload operations on folders within team space and received shares.
Non-Synchronizer or Backer
When a user is not granted Backer or Synchronizer permission, they can only perform bidirectional synchronization or one-way upload operations on folders within personal space and received transfers.
User interface
Sync backup
In the Synchronized Backup page, click Creating Synchronized Backups.
Create sync backup
In the Creating Synchronized Backups page, fill in the required fields Select local folder, Select cloud folder, and choose Synchronization type (default is bi-directional synchronization).
In the Advanced page, set sync filtering, sync throttling, and other parameters.
Sync details
Sync details include Synchronized completion, Synchronizing, and Synchronization failed.
Support sorting sync tasks by Cloud Name and Creation Time.
Support filtering sync tasks by synchronization status, type, and space.
Sync task management: support pause, cancel, set, and view synchronization, and view local/cloud sync files.
Precautions
The sync backup feature will occupy storage space on both local devices and the cloud. Ensure that there is sufficient storage space on local devices and the cloud for file synchronization and storage.
To ensure that local files can be synchronized to the cloud in a timely manner, keep the client running in the background and maintain a smooth network connection.
During the creation of sync backup, if there are files or folders with the same name in the same path locally and in the cloud, the following automatic processing will occur:
If files exist on both ends, the local file will be uploaded to the cloud as a new version, and the original cloud file will be saved in the history version.
If one end is a file and the other end is a folder, one of them will be automatically renamed.
