I think rsync notes the deleted files even in an incremental but
it bases the incremental on the last previous full, so subsequent
incrementals transfer the same new files each time until you do
another full. Rsync 'fulls' don't actually transfer the existing
files again but the options passed in the command specify that the
full runs ignore the timestamps and do checksum comparisons
over all the files. If you trust the timestamp/size comparison
on existing files you could probably speed the system up
considerably by changing the options in the rsync full
command and running fulls every time.
