BACKUP METHOD OF DATA, RESTORATION METHOD OF BACKUP DATA, NETWORK STORAGE DEVICE, AND NETWORK STORAGE PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a network storage device capable of shortening the time up to the restoration of backup data, when performing multiplexing of data in a plurality of storage devices, and minimizing the deviation of data between the storage devices at the restoration of data. PSOLUTION: This network storage device 1A comprises a storage device 2A and a controller 3A. A plurality of logic storage sections 2aSB1/SBand 2aSB2/SBconsisting of a primary area P for storing original data and a backup area B for storing backup data are set in the storage device 2A, and the individual logic storage sections 2aSB1/SBand 2aSB2/SBare associated with a plurality of other network storage devices to mutually retain the backup data with the network storage device 1A.
