PURPOSE: A data backup method, device, and system based on a risk detection, and a recording medium for the same are provided to improve data stability by judging a risk based on the amount and direction of the detected acceleration, and instantly backing up the running data. CONSTITUTION: A risk detection part(110) is equipped with a sensor and generates a sensing value. A risk judging part(120) judges a risk by comparing the sensing value with a reference value, and outputs a judgment value according to a judgment result. A data storage part(140) stores data. A control part(130) selects backup data to be backed up in response to the judgment value, and stores the selected data in the data storage part. The risk detection part detects acceleration through an acceleration sensor, and generates the sensing value. [Reference numerals] (110) Risk detection part; (120) Risk judging part; (130) Control part; (140) Data storage part
