copying a self-boot dc backup

I am trying to make a back up of a self boot dc cdr. (note I am not trying to burn a d/l image, I have already done that. I want to make a copy of the disc I downloaded and burned.)

Do I have to use disc juggler or clonecd? Is there a program for linux which can do this?

HOW ABOUT THIS????
1.copy all the visible files on cd
2.mkisofs to make an iso image of the files.
3.add the self boot audio track with cdrecord
4.add the iso track using -xa1

Anyone know if this works???
Feel free to email me.
