--- Comment #5 from Wayne Davison <wayned at samba.org> 2013-07-12 17:54:43 UTC ---
Lookup the --checksum option and the section in the manpage on rsync's "quick
check" algorithm for checking if a file needs to be transferred (e.g. if
name+size+mtime match).  If the mtime has changed, rsync has no way of knowing
that file's data is unchanged without a pre-transfer checksum comparison (-c),
or by doing the transfer and finding that all the checksum blocks actually
matched (so obviously the latter is still a file transfer).  It does not treat
a 0-length file specially in this regard.
