What is it you hope this backup disk to do? Why can't you use the debian-install CD in rescue mode to boot up the system in the event of a boot failure? Why do backups need to be bootable? Personally, I put my backups in a tarball (spit to fit on each piece of media) and pipe it through openssl to encrypt it. To restore from bare-metal, I do a basic reintall then retreive the tarball pieces, cat them together in /var/local/bacup, unencrypt it, then untarball it to its directory, then move things around with mc or rsync. My size needs are modest: it all fits on one 4 GB USB stick (set up to boot per the hd-media installer manual instructions) or on a small set of CDs or one DVD.
