  I don't think you can reliably figure out where the script was loaded 
from, after all it didn't even had to be loaded from file system.

  guess you know it but just in case: general practice is to put script 
in some bin dir (~/bin or /usr/local/bin or 
/opt/myVeryOwnBackupSystem-version/bin or something along those lines) 
and use a command line argument to specify directory to process 
(script.sh --dir /media/sda1/backup).
