摘要： A power reducer for data backup stops a power supply one after another for each memory whose backup has been completed, thereby reducing power consumption for battery during the backup lengthening a data backup time. The power reducer for data backup in a device includes an external power supply unit supplying power to the device, auxiliary power supply unit charging based upon the power supply from the external power supply unit and supplying auxiliary power to the device when the power from the external power supply unit is stopped, a cache memory having first and second memory units and recording a part of data stored in a storage medium, and a controller controlling power from the auxiliary power supply unit to the device and stopping power to the first or second memory unit one after another.
