System and method for reconstructing data associated with protected storage volume stored in multiple modules of back-up mass data storage facility

摘要

A computer program product is used with a programmable device to provide a data item reconstruction element for reconstructing information stored on a back-up information storage subsystem associated with at least one protected volume. The back-up information storage subsystem includes a plurality of storage media, each associated with one of a plurality of sets, the information associated with the protected volume being stored on storage media associated with one of the sets. The data item reconstruction element during the reconstruction operation retrieves in parallel information from a plurality of the storage media associated with the one of the sets on which information associated with the at least one protected volume is stored, to obtain the information which is associated with the protected volume.
