PROBLEM TO BE SOLVED: To restore the state of a system when a fault occurs and to output the state to secondary storage as fault information. SOLUTION: When the fault occurs, a fault information collection device 15 collects the state of the system at that time to a fault information collection device 14 and stores it in a memory device 16. A recovery execution means 12 executes rolling back. When the fault occurs again after a processing is resumed, the state of the system is restored based on information stored in the memory device 16 and outputs the stored state of the system to secondary storage. |
