I thought rsync was more difficult to use than it is. In the 
section on "how it works"

http://everythinglinux.org/rsync/

you need an rsyncd running at the other end

As it turns out it takes about 75 secs for rsync to sync up 
the two ends before it starts copying. cp -auv --parents or 
Jeff's cpio are faster. rsync is simpler to use, you don't 
have to find the files to copy first.

Using the cp --parents or cpio method, if something goes 
wrong (eg I change the script and it doesn't work), I then 
run rsync to recover.

Sean Korb's idea of doing both, ie selecting the new files 
then rsyncing them seems best. I know the directories that 
have just been copied, so I can run rsync on just them.

I haven't tried parallel yet. It only seems to work on 
commands rather than bash subroutines.

Thanks everyone

Joe
