TDSQL for MySQL supports full backup and incremental backup.

Backup Type

Full backup

You can set the backup retention period for full backups, which is seven days by default.

Incremental backup

Incremental backup is implemented based on binlogs, which are generated in real time. The binlogs use a certain amount of disk capacity, and are periodically uploaded to the TencentDB backup system.

Custom Backup Time

1. Log in to the TDSQL for MySQL console and click an instance ID or Manage in the Operation column to enter the instance management page.
2. On the instance management page, select the Shard Management tab and click a shard ID to enter the shard management page.
3. Select Backup and Restoration > Backup and Log Settings set the storage time.
   Storage Time: Data and log backups can be retained for one to seven (default) days.

   Note：

   TDSQL for MySQL's backup feature will be commercialized in June 2022. You will be able to set more backup and log storage days then.
