  That's a recipe for disaster.

Mmmm - fair point. My problem at the moment is we back up far too much data to keep a weekly (or even bi-weekly) full. Maybe I should revisit our backup list :)

I've been wondering about how safe data is in a duplicity archive - what happens if one of the volumes is corrupted? Do you lose all data from that volume onwards? Do all increments from that increment onwards become invalid?
