Abstract: On the basis of deep research on characteristic of embedded system, multithreaded and dynamic link libraries technologies. According to the design concepts, system functions and characteristic of Backup/Restore are analyzed, and its holistic design is finished, every functional module is defined, the service logic is described and the procedure of backup/restore is analyzed. The solution is simple and practical, needing a little system resource, and it has good robustness, scalability and portability. And then realize this software system based on Windows CE.NET and PDA software and hardware platform.
