Try using the command:
/usr/bin/growisofs -use-the-force-luke=tty -quiet -R -J -Z
/directory/to/backup/filename

The -use-the-force-luke=tty is an undocumented option to the growisofs
command, that you can only find by reading the source code. This is the
only way to overwrite a dvd that already has a file system on it from a
script that I'm aware of.
