摘要： A method in a data processing system for automatically terminating or resuming backup copy sessions after an abnormal interrupt or reset notification occurrence during a backup copy process. A status indication is entered into activity tables associated with a plurality of storage subsystems and devices within a data processing system in response to initiation of a backup copy session. Status indications are then entered upon successful completion of a backup copy session within the data processing system. The indications within the activity tables are reviewed to determine the status of a backup copy session upon restarting a resource manager, abnormal termination of a backup copy program, or an operating system initial program load. If a backup copy session has been initiated but not completed, the backup copy session is then terminated. The indications within the activity tables are also reviewed to determine the status of a backup copy session if a reset notification is raised by a storage subsystem. The tracks extents which are active for a volume associated with a particular session identification are determined. A comparison is then made between the tracks extents which are active and the volume and extent information associated with a physical session identification. If a match exists between the tracks extents which are active and the volume and extent information associated with a physical session identification, the backup copy session resumes. If a match does not exist, the backup copy session is terminated.

摘要： A method and system for the dynamic allocation of a buffer storage space during backup copying. Backup copying of designated datasets representing point in time consistency may be performed in a data processing system on one or more storage subsystems concurrent with data processing system application execution by suspending execution only long enough to form a logical to physical address concordance and thereafter physically backing up the datasets on the storage subsystems on a scheduled or opportunistic basis. A particular area of an established buffer storage space is dynamically allocated for each designated dataset to be backed up. The designated datasets are then stored in the particular areas and indexed. After all designated datasets to be backed up are copied to an alternate storage subsystem location, the buffer storage space is released.

摘要： Backup copying of designated datasets representing a first selected point in time consistency may be performed in a data processing system on an attached storage subsystem concurrent with data processing system application execution by first suspending application execution only long enough to form a logical-to-physical address concordance, and thereafter physically backing up the datasets on the storage subsystem on a scheduled or opportunistic basis. An indication of each update to a selected portion of the designated datasets which occurs after the first selected point in time is stored and application initiated updates to uncopied designated datasets are first buffered. Thereafter, sidefiles are made of the affected datasets, or portions thereof, the updates are then written through to the storage subsystem, and the sidefiles written to an alternate storage location in backup copy order, as controlled by the address concordance. At a subsequent point in time only those portions of the designated datasets which have been updated after the first selected period and time are copied, utilizing an identical technique.

摘要： A method in a data processing system for generating a backup copy of designated datasets during concurrent execution of an application. Upon receiving a request for a backup copy, execution of an application is suspended. A dataset logical-to-physical storage system address concordance for the designated datasets is formed, and execution of the application is resumed thereafter. A resource manager is established to manage all input and output functions between storage subsystems, storage subsystem memory associated with each of the storage subsystems, and a temporary host memory during formation of the backup copy. Formation of the backup copy is accomplished on a scheduled or opportunistic basis by copying the designated datasets from the storage subsystems and then updating the address concordance in response to the copying. Application updates are processed during formation of the backup copy by buffering the updates, copying the affected uncopied designated datasets to a storage subsystem memory, updating the address concordance in response to the copying, and processing the updates. Designated datasets can also be copied to the temporary host memory in the event the number of designated datasets in the storage subsystem memory exceeds a threshold number. Finally, the designated datasets are copied to an alternate storage memory from the storage subsystem, storage subsystem memory and temporary host memory utilizing the resource manager and the altered address concordance to create a specified order backup copy of the designated datasets from said copied portions of the designated datasets without user intervention.
