That's an important little detail there.  At one time we did have a
problem in Samba that manifested itself as rsync recopying data.  Had
something to do with the time stamps and has since (I believe) been
fixed.

Wrt, the suggestions to use -av...  This probably doesn't apply to a
cifs share, IAC, but...  For those of you using rsync on *NIX to *NIX,
be aware at -av might not do everything you would like.  For one thing,
it does NOT preserve hard links and will result in two (or more) files
on the target instead of one hard-linked file.  It also does not
preserve extended attributes (which DEFINITELY does NOT apply to a CIFS
share).  Depending on what you are doing, you may want to a -H to
preserve hard links, and -A (and maybe also -X) for extended attributes.
When I'm going ext3 to ext3, I'm always using -avAHX.
