I like
	- kreatecd,
	- cdbakeoven,

both are available as .deb files from http://134.28.62.2/debian.

partimage can create a compressed HDD image (backs up only those sectors
that are actually used) which can be played back 1:1 to the disk.

If you only want a simple backup, "tar cvMzf /" is your friend. Or, if you
want to be a little more k3wl, use something like (NB: MUST be customized)

---------------------------------------------------------------------------
	#!/usr/bin/perl -w
	#
	# Backup files, sort by size, so that in average a _single_ file
	# restore will be fastest. (biggest files last)

	use strict;
	require 5;      # needs perl5
	use File::Find qw( &finddepth );

	my @backupz = qw( /foo /bar /bletch/blort );
	my @nobackz = qw( .netscape/cache tmp scratch );
	my $regex = '/(?:' . ( join '|', @nobackz ) . ')/';
	my @filz = ();
	my $listify = sub { push @filz, [ $File::Find::name -s ]
		unless $File::Find::prune = $File::Find::dir =~ m{$regex}o };

	finddepth $listify, @backupz;

	open CPIO, "| cpio -o -Hcrc | bzip2 -9 --verbose > $backupfile" 
		or die "oops: $!";

	$, = "\n";

	print CPIO map { $_->[0] }
		sort { $a->[1] <=> $b[1] or $a->[0] cmp $b->[0] } @filz;
	
	close CPIO;
---------------------------------------------------------------------------

(quick 'n' dirty, don't sue me for syntax errors, it wasn't my idea
anyway).

You can use my 'makecd' script. Simple bash solution, call it like

	makecd $cd-label $DIRECTORY

if you symlink it to "makeimg", it will create an iso-image first and must
be called like

	makeimg $cd-label $directory $iso-image-file

You can then

	makecd test /mount/point

to test your burned CD.

Yes. Read the CD-Burning-HOWTO. It's all explained there, in good detail.
