V$BACKUP_SET_DETAILS provides detailed information about the backup set. This view will contain an extra row for each backup session that invokes BACKUP BACKUPSET (that is, creates new copies for the same backup set or copies backup set information from disk to tape). However, the remaining values of other columns belong to the complete backup set.
