Abstract:
Database performance may be improved by creating additional backups from an existing backup, rather than the original database or audit log source. A second backup may be created from a first backup by copying the files from the first backup to the second backup. The replication from a first backup to a second backup with modification of the file history information allows identical backups to exist on different types of storage devices, including virtual storage devices. Continue functionality may be implemented during a move function to restart replication at a new starting point while retaining the existing move set. Tape-type-override functionality may be implemented during the replication to replace the tape type for the backups with another compatible type while retaining the original type for history file entries, tape trailers, and messages.
