Description |
NOTE:
Once a DB instance is created, a backup is restored to a new instance, or a minor version is upgraded, a full backup is automatically triggered by default and this function cannot be disabled. Backups that are being created can be stopped. If such a backup task is stopped and the first full backup of your instance is not complete, no backup is available for restoration. To stop a backup, submit a service ticket to apply for required permissions. |
