Norton Ghost 2003 will back up a static Linux system.  You have to boot
the CD and ghost it that way.  We use this to clone systems all the
time.

Can you "snapshot" a system and burn it to CD?  Sorta.  You must keep in
mind that you'll only see the stuff that's currently committed to disk
at the time the file is read if you have files open for write (e.g.
/var/log/messages, etc.)--anything that's still cached in "dirty" disk
buffers will not be available.

You can create the CD in a number of ways.  The classic way is to create
a cpio archive using "find", then burning the archive to CD or DVD.  The
command would appear sorta like:

	find / -depth -path /proc -prune -o ! -type b ! -type c ! \
	    -type s -exec cpio -O < {} >>/path/to/cpio/archive

Conversely, you can use the output of find to create a list of files
to back up and feed mkisofs or growisofs with that list:

	# find / -depth -path /proc -prune -o \
	    -path /tmp/flist.lst -prune -o ! -type b ! -type c \
	    ! -type s -print >>flist.lst
	# mkisofs -path-list /tmp/flist.lst

Or use something like amanda to do backups to tape or another hard
drive.
