A method and system in a data processing system for administering multiple backup copy session, where activity tables are associated with a plurality of storage subsystems and devices. A status indication is entered into said tables upon initiation of a backup copy session as well as upon successful completion of such a session. Said indications are reviewed from time to time such as at the restarting of a resource manager, abnormal termination of a backup program or an operating system program load. If a backup session has been initiated but not completed, it is terminated. Said status indications are also reviewed if a reset notification is raised by a storage subsystem. If a match exists between the tracks extents which are active and the volume and extentt associated with a physical session identification, the backup copy session resumes, otherwise it is terminated. |
