An LU management table 61 that associates and stores the LU# of the P-Vol 10p and the LU# of the S-Vol 10s is provided. The CPU 53 specifies the LU# of the S-Vol 10s constituting the save source of the data with respect to the magnetic tape cartridge 74, acquires the LU# of the P-Vol 10p associated with the specified LU# from the LU management table 61, reads the saved data from the magnetic tape cartridge 74 storing the data by means of the magnetic tape drive 71, and stores the data read from the magnetic tape cartridge 74 to the P-Vol 10p with the acquired LU#. As a result, the data can be restored easily and properly to the P-Vol 10p. |
