In a system for taking over data of the present invention, a first data processing unit processes a processing data following an execution of a program. A second data processing unit transfers a takeover data necessary for resuming a process from the first data processing unit, when there is some trouble with the first data processing unit. A volatile storage unit stores the takeover data and the processing data to be processed by the first data processing unit. A change unit changes the takeover data stored in the volatile storage unit into a new takeover data following the execution of the program by the first data processing unit. A nonvolatile storage unit is connected to the first data processing unit and the second data processing unit, and stores the takeover data. A demanding unit issues a transmission demand for transmitting the processing data stored in the volatile storage unit to one of the nonvolatile storage unit and a network. A rewriting unit rewrites the takeover data stored in the nonvolatile storage unit into the new takeover data changed by the change unit when the demanding unit issued the transmission demand.
