Information processor, computer readable recording medium which records data evacuation program, and data evacuation method

A computer readable recording medium which records a data evacuation program for controlling a computer to execute a data evacuation process for evacuating data stored in a memory of an information processor that is driven by a battery, the recording medium controlling the computer to function as:

• a load information collecting unit acquiring load information representing an electric load of the information processor;
• a battery residual quantity detecting unit detecting the battery residual quantity of the battery;
• an evacuation residual quantity setting unit setting an evacuation residual quantity as a residual quantity of the battery that corresponds to electric power necessary for executing a data evacuation process for storing the data, on a nonvolatile recording medium, which is stored in the memory of the information processor, based on the load information collected by the load information collecting unit, and based on a difference between a battery residual power that was detected by the battery residual quantity detecting unit at a beginning of a prior data evacuation process and a battery residual power that was detected by the battery residual quantity detecting unit at a completion of the prior data evacuation process, and storing evacuation residual quantity information representing the set evacuation residual quantity in a set information storage unit;
• and
• an evacuation control unit controlling execution of the data evacuation process based on the battery residual quantity detected by the battery residual quantity detecting unit and the evacuation residual quantity information stored in the set information storage unit, wherein
• the evacuation control unit executes the data evacuation process when the battery residual quantity detected by the battery residual quantity detecting unit is less than or equal to the evacuation residual quantity set by the evacuation residual quantity setting unit.

A data evacuation method for a computer to evacuate data stored in a memory of an information processor that is driven by a battery, the method comprising:

• detecting a battery residual quantity of the battery, by a battery residual quantity detecting unit;
• acquiring load information representing an electric load of the information processor, by a load information collecting unit;
• setting an evacuation residual quantity as a residual quantity of the battery that corresponds to electric power necessary for executing a data evacuation process for storing the data stored in the memory of the information processor on a nonvolatile recording medium, based on the load information collected by the load information collecting unit and based on a difference between a battery residual power that was detected at a beginning of a prior data evacuation process and a battery residual power that was detected at a completion of the prior data evacuation process, and storing evacuation residual quantity information representing the set evacuation residual quantity in a set information storage unit, by an evacuation residual quantity setting unit;
• and
• controlling execution of the data evacuation process based on the battery residual quantity detected by the battery residual quantity detecting unit and the evacuation residual quantity information stored in the set information storage unit, by an evacuation control unit, wherein
• the data evacuation process is executed when the detected battery residual quantity is less than or equal to the set evacuation residual quantity.
