Thanks Oli,

This is very helpful. I'll do it in the way you suggest. I'm going to do
some test runs with about 5Gb anyway on a late night schedule. I should
also be able to divide up the data into 4 chunks of 10Gb or so, running
as separate processes - if one fails, I'll have 3 that are OK.

The byte count in the log file will be very useful. I'll have to read up
on Robocopy as I haven't used it for a LONG time!
