If your CD or DVD is loaded (not mounted) at /dev/cd0, the following command
will create an iso image in the current directory:
dd if=/dev/cd0 of=filename.iso bs=2048
If you want an easy process, you can put this in a script, followed by a
growisofs command to burn the file to another DVD device, allowing the
script to overwrite the previous DVD iso file. Or you could write a script
where you supply a name for the iso image file to maintain backup images.
I hope this helps.
