Abstract
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.
