The biggest difference is probably that backuppc creates a separate
file (actually 2 links) for every new file on the source. With many
small files the file creation overhead would be more than compression
and checksums - depending partly on CPU speed/disk speed. Incrementals
should run much faster and subsequent fulls at least slightly faster.
