Dear @Wasan, I tried doing this method but the cable (CS1W-CN226) wasn't compatible with my laptop so I used a converter to convert from "serial" terminal to USB but unfortunately when I tried to make the "back up" it gave "communication fail" . I don't know how to solve this problem to be enabled to do this back up.
when I connected it to laptop, first I let it to download the driver of the piece then I start trying to do the back up.
