I'm in Taiwan right now so I don't have access to my home system.
In general my laptop does full dumps about 2-3 times faster with
rsyncd compared to smbclient.  The first dump isn't much faster
than smbclient.  Incrementals are about the same; maybe smbclient
is a bit faster for incrementals because rsyncd/cygwin is a but
slow building the directory tree.

The performance impact on the client during backups is still noticeable,
but the full dump duration is shorter.

I'd recommend trying it on a system for yourself.

Rsync 2.5.6 includes an optional patch from me that substantially
improves the performance with cygwin.  Sometime I've been meaning
to build a zip file that includes the minimal install of the patched
rsync and cygwin dlls plus a README.  If you want to create this that
would be great.  I'll release this on the perlrsync project.
