ABSTRACT:
Disclosed is a system, method, and program for data backup. A backup copy of source data is created. A backup dataset inventory is created when the backup copy is created. The backup dataset inventory includes a backup dataset identifier and an originating source volume identifier for cach dataset of the source data. The backup copy is copied to a storage medium. A storage media inventory is created when copying the backup copy to the storage medium. The storage media inventory includes the originating source volume identifier and a storage media identifier for each dataset of the source data. This single backup scheme eliminates having to issue both image copies for individual dataset recovery, as well as, separate full volume dumps for recover of failed physical volumes or to recover an entire application.
