When a power supply (2) is lost, a server (10) copies the status of the server (10) to a storage device (40). In a specified time interval, the server (10) copies a difference in the status of the server (10). The server (10) predicts the time needed to copy the difference. Subsequently, the server (10) determines whether the predicted time is longer than the time it takes a battery module (50) to operate the server (10) when the power supply (2) is lost. If the server (10) determines that the predicted time is longer than the time it takes the battery module (50) to operate the server (10), said server (10) shortens the time interval in which copying is executed. |
