Abstract
A method and system for integrating migration level two (ML2) and backup tape processing provide for the backup, archival, and/or restoration of ML2 tape files without the use of tape mounts. In this manner, the amount of data movement required to recover from data loss is significantly reduced. Tape files may be recovered to their original status, even if the file has migrated to ML2. The status of the data is preserved after such a recovery operation. In this manner, data movement is reduced because no remigration of data is required after a recovery.
