Recently upgraded to vista and for the life of me couldnt get the vista to work with rsyncd running from cygwin. Would always stop with a code 12 error and not alot else. I just run rsyncd or rsync with the daemon option as I dont belive the cwrsync works as a service yet on vista.
Now in the backuppc config options for rsyncd and rsync there is a hard link option I just removed that and it seems to work not sure why vista cant deal with that option but if you remove it, everything works as it did before on windows 2000 / XP.
