PROBLEM TO BE SOLVED: To provide a technique for partially updating software while securing redundancy.SOLUTION: While a first system program is in an active state and a second system program is in an inactive state, when a communication unit receives an update instruction file, an information processing device changes a start-up system program indicated by start-up management information from the first system program to the second system program, restarts the information processing device by using the second system program as the start-up system program, synchronizes files of the second system program which are not in synchronous states with files of the first system program, and when the file synchronization is completed, changes the start-up system program indicated by the start-up management information from the second system program to the first system program. |
