The web interface should show a 'partial' until the backup completes. I
don't have one in that state so I'm not sure how much other info you
get. A brute force way to check is to go to the backuppc pc/hostname
directory and do a 'du' to see how much is there after each run - or
something like a 'find -ctime -1 .'

The main difference is that fulls do the equivalent of --ignore-times to
the rsync run and rebuild the archive tree. The checksum comparison
takes some extra time but not much bandwidth.
