ABSTRACT:
A data processing system providing disaster recovery and using a client-server configuration provides a method and apparatus for reclaiming off-site storage volumes without requiring the volumes to be mounted or transported to the primary site. The system includes primary volumes and resident copy volumes at the primary site and off-site storage volumes for disaster recovery at the remote site. The system first determines which off-site storage volumes are eligible for reclamation. For each eligible off-site volume, the system locates, within the primary site, a primary copy of every file remaining on the off-site volume that is still required for disaster recovery. These primary copies are then copied to a resident recovery volume at the primary storage site. The eligible off-site volume is then marked empty, and the resident recovery volume is classified as an off-site volume. The resident recovery volume is then transported to the remote storage site and the empty off-site volume is returned to the primary storage site to be reused as a resident copy volume.
