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.
