    Consider the following script. You may want to switch to using scp rather
    than rsync, and you may choose to hardcode the SSH key rather than passing it
    in as the first argument. You might also want to change how $DESTROOT is set
    to match the paths you want to use. Finally, you will want to add something like:

            cd ${DESTROOT}/..
            ARCHIVEFILE=/home/SOMEUSER/archive/backup`date "+%Y%m%d"`.tgz
            tar cf - ${CLIENT} | gzip --best > ${ARCHIVEFILE}

    ...just before the final done. Test things out by hand for a while (or on a
    machine-by-machine basis), and then set this up in cron.

# operate on that host.
#
# In other words, if you configure one host at a time to backup okay
# by adjusting SSH keys and such, running "./backup.sh _ident_ *.com"
# at a later date will backup all of the hosts manually configured
# automaticly.  If a host is down, it will be skipped without its
# files being deleted by the "rsync --delete" or "rm" commands
# (if enabled; see below).
