Description: A data auto backup system and method is proposed, applicable in a computer system connected with an external storage device for backing up data of the external storage device to the computer system during a power-off state of the computer system. The computer system includes a bus interface, a storage module, an input/output interface, and a power module. The data auto backup system includes: an input unit for inputting a predefined signal; a memory unit for storing a backup program; a detection unit for detecting whether the external storage device is connected with the bus interface and generating a corresponding signal; a processing unit for receiving and processing the corresponding signal so as to generate a first driving signal, and executing the backup program according to the predefined signal so as to generate a second driving signal; and a control unit for receiving the first and second driving signals.
Technology Used : Java , Swing ,FTP and TCP
