======================================
2.01 retention policy (retention policy)
Configure retention policy to recovery window of 3 days;
Configure retention policy to redundancy 3;
Configure retention policy clear;

Backup policy persistence
There are two retention policies: one is the time policy, which determines that at least one backup can be restored to the specified date, and the other is the redundancy policy, which requires at least several redundant backups.
Configure retention policy to recovery window of 5 DAYS;
Configure retention policy to redundancy 5;
Configure retention policy to none;
In the first policy, at least one backup is guaranteed to be restored to the point in time of the Sysdate-5, and the previous backup is marked as Obsolete. The second policy indicates that at least three redundant backups must exist. If there are more than three redundant backups, the backups are marked as redundant. NONE can invalidate the backup retention policy. Clear will restore the default retention policy.
