   • Delete data backup files.

     On the Data Backup tab, click Delete for the target backup.

     Note

     If the Delete button is unavailable, it means the backup does not meet one of the following conditions:

     • If log backup is disabled, you can only delete data backups that are older than 7 days.

     • If log backup is enabled, you can only delete data backups that are older than the specified log backup retention period. For example, if the log backup retention period is 7 days, you can delete data backups that have been retained for more than 7 days.

   • Shorten the data backup retention period.

     On the Backup Strategy tab, click Edit next to Basic Backup, and then shorten the Data Backup Retention Period.

     Note

     The system automatically deletes backups that exceed the specified retention period. For example, if a backup has been retained for 31 days and you change the retention period to 30 days, the 31-day-old backup is immediately deleted.

   • Reduce the data backup frequency.

     On the Backup Strategy tab, click Edit next to Basic Backup, and then select a less frequent backup cycle.

Reduce log backup size

     Note

     You can set the log backup retention period only when log backup is enabled.

   • Disable log backup.

     On the Backup Strategy tab, click Edit next to Basic Backup, and then disable Log Backup.

     Note

     After you disable log backup, the system immediately deletes all existing log backups, and point-in-time recovery becomes unavailable.

   • Reduce unnecessary INSERT, UPDATE, and DELETE operations, and minimize updates to large fields.

     All INSERT, UPDATE, and DELETE operations on the database increase the log backup size.
