   Some corrections to my own musing that I've discovered thus far:
# dd bs=1024 if=/dev/hda1 | bzip2 --best | ssh -2 -l [user]
[ipaddress] "cat - > /var/server-backup.bz2"

   tar is unnecessary because there are no directories. It would be best
   to compress it before it goes over the network. cat is taking stdin to
   stdout and bash is dumping stdout to a file. Is this any closer?
