Dynamic data backing-up system and method

The system comprises the module for monitoring files, the data analysis module and the data processing module. The method provided by the invention for backing up the data dynamically includes the following steps. In the step for monitoring the data, the file-monitoring module monitors the change of the data. When the user changes the data, the data information updated is transferred to the data analysis module. In the data analysis step, once the data information updated being received, the data ananlysis module picks up the thread ID of updating the data, the program name and the file name.In the thread step, once the user issues the backing up request, the thread is arranged to enter the data quene. In the step for backing up the data, based on the threads entered into the data queue,the data management module backs up the data.
