<P>PROBLEM TO BE SOLVED: To prevent fail in backup resulting from running out the remaining capacity of a battery. <P>SOLUTION: It is determined whether the remaining capacity of a battery is sufficient for transmitting full backup data of data to the host by Bluetooth (R) communication or not (step S24). If it is determined that the remaining capacity of the battery is sufficient for transmitting the full backup data, the full backup data are transmitted to the host by second radio communication (step S25). If it is determined that the remaining capacity is not sufficient, it is determined whether the remaining capacity of the battery is sufficient for transmitting incremental backup data to the host by Bluetooth radio communication (step S28). If it is determined that the remaining capacity of the battery is sufficient for transmitting the incremental backup data, the incremental backup data are transmitted to the host by the Bluetooth communication (step S29). <P>COPYRIGHT: (C)2010,JPO&INPIT |
