TencentDB for TDSQL supports full backups and incremental backups.
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 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.
