PROBLEM TO BE SOLVED: To smoothly perform reactivation by suppressing the mismatching of file versions between subordinate devices.SOLUTION: A storage device 110 includes an operation system 111; and a standby system 112. The operation system 111 and the standby system 112 are configured to store mutually independent versions of files. The plurality of subordinate devices 120 are configured to acquire the versions of files stored in the operation system 111 when an own system 100 is activated, and to perform processing on the basis of the acquired files. When partial subordinate devices 120a among the plurality of subordinate devices 120 are activated at a timing different from the activation time of the own system 100 during the operation of the own system 100, the partial subordinate devices 120a acquire the files being used for processing by the other subordinate devices 120b during operation among the plurality of subordinate devices 120, and perform processing on the basis of the acquired files. |
