Okay, in that case I think I've completely and utterly misunderstood
what a full backup is in backuppc terminology (and the difference to
an "incremental" backup).
I may have to resort to reading the documentation and/or the source
code a little more carefully. Or conduct tests to see what *actually*
happens on backup runs.
Thanks for your conscientious efforts in trying to explain. :)
Pete.
