Abstract:
1. An electronic device with an automatic backup function to deal with at least a first data stream, comprising: a main board; a data-sync chipset disposed on the main board for receiving the first data stream, wherein the data-sync chipset outputs at least a second data stream; a first storage unit electrically coupled to a first terminal of the data-sync chipset, wherein the second data stream is stored as a first file in the first storage unit; a wireless transmission module disposed on the main board and electrically coupled to a second terminal of the data-sync chipset, wherein both of the data-sync chip and the wireless transmission module are controlled and driven by a driver program; and a second storage unit electrically coupled to the wireless transmission module by means of wireless transmission, the second data stream being stored in the second storage unit as a second file, and the first file being substantially equal to the second file, wherein the data-sync chipset copies a third file to the second storage unit and overwrites the second file therein when the first file is modified to the third file but the second file is not modified yet.
