tencent cloud

TencentDB for MariaDB supports full backup and incremental backup, and backups are compressed with LZ4. For more information on how to use LZ4, please see Decompressing Backup and Log Files.

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 (30 days for finance cloud).

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.
