[Feature] Optimize the backup deletion policy - Retain Latest Backup

[wallyxjh]

Can the deletion strategy of database backup be optimized? The current backup deletion policy is to set an expiration time, after which all backups are automatically deleted. If you want to delete a backup after expiration, keep the last successful backup

Hi @wallyxjh ,

Your intention is to : Keep the latest backup file, even if it exceeds the retention period.
And user may specify the behavior through KB's backup policy, right ?
