When the virtual tape device 10 of the virtual library system 100 receives a data write request as a backup process, the physical tape devices 10 in the library devices 30a and 30b belonging to their own devices store the data stored in the logical volume. The migration process to save in a volume is performed. Subsequently, when the host 20 notifies the virtual tape device 10 of the export instruction, the virtual tape device 10 sends the data stored in the logical volume on which the migration process is completed via the network to the subcenter side library device 30c.
