You can configure the lifecycle of a backup schedule based on your business requirements. The lifecycle of a backup schedule indicates the retention period of backup sets that are generated based on the backup schedule. This topic describes how to modify the lifecycle of a backup schedule.
Prerequisites
A backup schedule is created in the Database Backup (DBS) console, or a default physical backup schedule is generated for an ApsaraDB RDS instance that is automatically connected to DBS. You cannot modify the lifecycles of backup schedules that are generated for cross-region ApsaraDB RDS backups in the DBS console. For more information, see FAQ about backup schedules for cross-region ApsaraDB RDS backups.
