I've not read the whole thread, but I see no reason you cannot use rsync.
If you need copies of things like the boot sector then just dd it to a file
and rsync it with everything else.
My backup server has the keys from each computer so it will allow scp to pipe
rsync to it without a login. Then just set cron to run dd and then rsync.
I had all but forgotten about rsync. Then one day I stumbled on it when
reviewing my backup policy. It totally rocks with secure shell. But then I
think you have already discovered that.
