A first backup policy specifies triggering backups at a first frequency and retaining the backups for a first duration. A second backup policy specifies triggering backups at a second frequency, less than the first frequency, and retaining the backups for a second duration, greater than the first duration. When two or more backups are to be triggered on a same day, a backup is allowed to proceed according to the first backup policy. A search is conducted for the allowed backup. If the backup is found, the backup is promoted as a backup conducted according to the second backup policy specifying a retention time of the second duration.
