Transferring Backups to a Specified OBS Bucket

You can transfer the generated automated or manual backups to a specified OBS bucket, or configure automatic backup transfer to an OBS bucket.

To manually transfer backups, submit a service ticket to request required permissions.
To enable automatic backup transfer or automatic binlog backup transfer, submit a service ticket to request required permissions.

Only physical backup files can be transferred to a specified OBS bucket.
When being transferred to an OBS bucket, encrypted backups will be decrypted first.
The maximum size of a single backup that can be transferred each time is 10 TB. If this limit is exceeded, the transfer task will fail.
Ensure that the target OBS bucket is available and has enough space. Otherwise, the transfer task will fail.
Expired or deleted backups will not be transferred.
Deleting the instance during a transfer will cause the transfer task to fail.
You need to configure permissions and add system roles for both manual and automatic OBS transfer. For details, see Permissions.
The transfer speed depends on the OBS upload rate, and the estimated time required may fluctuate.
Automatic transfer takes effect only for backups generated on and after the day when you enable the function. It does not apply to existing backups.

Backup	Parameter	Description
Automated backup, manual backup, and binlog backup	Destination OBS Bucket	Select an OBS bucket.
	Destination Bucket Prefix	A destination bucket prefix indicates where you want to store your backup data in an OBS bucket. It is in a folder structure and ends with a slash (/).
	Transfer Period	Backups are transferred by day. Select at least one day in a week. The transfer period uses the standard UTC time zone. Backups generated on the current day will be automatically transferred to the destination OBS bucket the next day. For example, if you select Monday, the backups generated on Monday will be automatically transferred to the destination OBS bucket on Tuesday. Automatic transfer takes effect only for backups generated on the day when the function is enabled and later. Existing backups will not be automatically transferred.

After the task is submitted, return to the Instances page, choose Backups > Download and Transfer, and check the execution result of the automatic transfer task on the next day.
