That's a rather old message, last year in fact.  As of the 0.6.xx
series, duplicity can now resume a failed backup.

A full backup, by definition, backs up all the files, so yes, a full
backup copies all the files.  Best practices say that you should do a
full backup at least once a month and incrementals every working day
after that.  I prefer a full backup weekly, with weekday incrementals.

Let me explain myself, I have never backed up a full disk in my life,
and that's 40+ years in this field.  To me, a FULL backup is a complete
backup of the DATA on the disk, nothing more.  To backup something that
is on an install CD is a waste of time, especially in todays environment
of high bandwidth networks.  I've never lost data and quite often a
failed disk was a blessing because I could take the time to upgrade.
