TDSQL for MySQL supports full backups and incremental backups.

Backup Type

Full backup

You can set the start time and retention period for full backups. By default, the backup starts at 00:00–05:00 AM, during which the performance is relatively low. The retention period is 7 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 the instance name or Manage in the "Operation" column to enter the instance management page.
2. Select Shard Management and click the shard ID to enter the shard management page.
3. Select Backup and Restore > Backup and Log Settings and click the icon as shown below to set the storage period.
   • Backup cycle: the backup task is performed every day by default.
   • Storage time: data and log backups can be retained for 1 to 7 days. Retention time is set to 7 days by default.
