YDNRC.  Half Duplex 100M is a bit more common for sevaral reasons.  There were 
a lot of incompatibilities between Cisco routers and 3Com 100M NICs which 
cause anything from incorrect autonegotiation to complete connection 
failures.  Some of that's been ironed out with newer hardware, but a lot of 
sites still set everything to Half Duplex.

Still, I have noticed other conditions in which Linux boxen don't seem to make 
effective use of the bandwidth when running a single file transfer.  It's too 
infrequent a problem for me to persue, but would be of interest to anyone 
doing a backup like yours regularly.
