I often do this with netcat.

On the server
nc -l -p 5050 | pipebench > backup.dat

On the client
dd if=/dev/hda bs=1M | gzip -9 | nc server 5050

Pipebench is a great little util for watching speed/total transferred bytes.. always keep a copy around.

Every time anyone asks me to do any major work on their machine, this is always the 1st step, so I 
can undo anything I might do wrong (especially when dealing with windows). I just boot knoppix on 
the box and 'ave at it.
