A while ago I wanted to do the same thing and to make it possible with mkisofs I added the --root/--old-root command line options. The only difference compared to your method is that each day ends up being a separate directory, so by mounting the last session you have access to each snapshot of the week at once. Unchanged files are still only stored on the disc once. These options are now included in the standard mkisofs. For a usage example see the attached script. It uses growisofs to burn writable DVD, but the same method also works with cdrecord + writable CD. -- Bye, Patrick Ohly -- Patrick.Ohly@gmx.de http://www.estamos.de/
