Document Type and Number:
Japanese Patent JP2019046283
Kind Code:
A
Abstract:
To control an increase in power supply of a backup power source part.SOLUTION: A controller 1 includes: a control unit 1a; a storage unit 1a-1 provided as a pair with the control unit 1a; a control unit 1b; and a storage unit 1b-1 provided as a pair with the control unit 1b. The control unit 1a transmits, to the control unit 1b, backup target data d1 stored in the storage unit 1a-1. The control unit 1b performs copy processing of copying the backup target data d1 into a non-backup target region r0 of the storage unit 1b-1. Moreover, the control unit 1a blocks at least one of backup power supply to the storage unit 1a-1 and backup power supply to itself after completion of the copy processing. Then the control unit 1b transfers backup target data d2 stored in the storage unit 1b-1 and the backup target data d1 to a backup storage unit 1c to perform data saving processing.SELECTED DRAWING: Figure 1
