Abstract:
A flashcopy of a source storage volume to a target storage volume is initiated. The content of the source storage volume is stored on the target storage volume in a space efficient manner. The space requirement of the stored content on the target storage volume is monitored. The flashcopy is terminated when the space requirement reaches a predetermined level. The stored content on the target storage volume is copied to a backup storage medium. A new flashcopy of the source storage volume is initiated.
