In the end I pretty much gritted my teeth and let it get on with it.
It took about 2-3 days (albeit with some big gaps as I did the copy in
chunks).

Good point about sticking the USB disk directly into the pc. I very
nearly did this as a test but was part way through a copy when it
occurred to me!

This is clearly a weak point for all these home systems heavy storage
requirements.  Really need a direct copy system that's easy to use
and doesn't rely on pumping everything around the LAN.  The UMAX NAS
boxes don't provide such a facility and I don't know if others do but
it might be worth adding the existence of such 'backup from NAS /
replicate' to your evaluation criteria if you are looking for one.

Hope it gets cracked before I need to copy off the 1Tb drive in the
future!
