Thanks, everyone, for the guidance on backing up. I've have a WD 
Passport 500GB (pocket size). I've partitioned it as I have the HD in 
my machine nad made copies to two separate halves of the two separate 
halves I have on the machine, using Carbon Copy Cloner.

It seemed to me that it had no incremental back up capability. Am I 
wrong? So I am trying out Deja Vu which definitely does do increments 
(to the CCC back up, actually) ... although I can't see how to turn 
that feature off, short of having it work to a blank disk.

I'll see how that process goes.

Many thanks again.

Best regards, Geoff
