         5 . The automatic backup method of  claim 1 , wherein the data-sync program further comprises at least a function option, and the function option defines a first data folder of the first storage unit as a sync data folder. 
     
     
         6 . The automatic backup method of  claim 5 , wherein the data-sync program is performed to copy the first data folder of the first storage unit to the second storage unit and overwrite the original data therein during a predetermined period of time. 
     
     
         7 . The automatic backup method of  claim 1 , wherein the first storage unit is an internal hard drive and the second storage unit is a portable external hard drive supporting the wireless data transmission. 
     
     
         8 . The automatic backup method of  claim 1 , wherein the data-sync program further performs a third step for copying a fifth file to the first storage unit and overwrites the third file therein when the second file is modified to the fifth file and the third file is not modified yet. 
     
     
         9 . The automatic backup method of  claim 1 , wherein the data-sync program instructs a first transmission rate of the first storage unit to be equal to a second transmission rate of the second storage unit. 
     
     
         10 . The automatic backup method of  claim 1 , wherein the wireless transmission module comprises an IEEE 802.11b or an IEEE 802.11g WLAN transmission module. 
     
     
         11 . The automatic backup method of  claim 1 , wherein the first data stream is provided by a CPU. 
     
     
         12 . A computer system with automatic backup function to deal with at least a backup data, comprising:
 a first data stream is transmitted to a first storage unit and a second storage unit, the first data stream is stored as a first file in the first storage unit, and the first data stream is transmitted by means of wireless transmission and stored as a second file in the second storage unit, the first file being substantially equal to the second file; and   a third data stream is transmitted to the second storage unit and overwrites the second file as a third file therein when the first file is modified to the third file but the second file is not modified yet.   
     
     
         13 . A wireless automatic backup system, comprising:
 a remote computing system having a first storage unit and a wireless module; and   a wireless storage unit connected to the wireless module of the remote computing system; wherein the wireless automatic backup system performs a backup step to overwrite a first file in the first storage unit by copying a second file in the wireless storage unit to the first storage unit.   
     
     
         14 . The wireless automatic backup system of  claim 13 , wherein the wireless automatic backup system further comprising:
 a second remote computing system, said second remote computing system having a second storage unit and a second wireless module;   wherein the wireless automatic backup system overwrites the second file in the wireless storage unit by receiving a first data stream, said first data stream is transmitted to the wireless storage unit when a second data stream is transmitted to the second storage unit in the second remote computing system.   
     
     
         15 . An automatic backup system, comprising:
 a first sync data disk drive in a first storage unit;   a second sync data disk drive in a wireless storage unit; and   a program determining whether a file in the first sync data disk drive is modified, and the program copies the file in the first sync data disk drive to the second sync data disk drive in the wireless storage unit during a predetermined period of time.   
     
     
         16 . The automatic backup system of  claim 15 , wherein said program further having a function option for the purpose of selecting a sync cycle used to configure said predetermined period of time. 
     
     
         17 . An automatic backup method, comprising:
 a sync data folder mode and a folder is selected by a user;   browsing the folder and configuring the folder as a first sync data folder;   configuring a second sync data folder in a second storage unit; and   copying all data in the first sync data folder to overwrite the second sync data folder in the second storage unit when data in the first sync data folder is modified.   
     
     
         18 . The automatic backup method of  claim 17 , wherein said automatic backup method further comprising:
 selecting a sync cycle used to configure a period of time for automatic backup.   
     
     
         19 . A computer-readable recoding medium for storing an automatic backup program, said automatic backup program comprising the steps of:
 providing a sync type for setting a automatic backup mode;   selecting a first disk drive to be mirrored if the selected sync type is a disk mirroring mode;   selecting a first folder to be a sync data folder if the selected sync type is a sync data folder mode;   browsing said first disk drive or said first folder;   configuring a second disk drive or a second folder in a second storage unit; and   copying data in the first disk drive or the first folder to overwrite the second disk drive or the second folder in the second storage unit when data stored in the first disk drive or the first folder is modified.
