How to backup grand theft auto san andreas?

I want to add a mod to grand theft auto san andreas, how do i back up the save file?How to backup grand theft auto san andreas?
Simple just copy the file thats already in the directory I dunno say for example its a DAT file just right click and copy and place it in a folder.



If it is like a car mod get a programme called SAMi and tell it to make a backup.



Also SAMi is crap at everything else



Also put that DAT file into the directory (Whichever) or the game will not respond.
