First, remove these...

These options have been deprecated - and can CAUSE problems - for many, 
MANY years.

Next, since you had those still lingering around (I'm assuming from an 
ancient initial install, or from following some stupid long irrelevant 
$random_howto on the internet), go ask for help on the Samba support 
list evaluating your smb.conf settings and see if you have any other 
miscreants in there...

Then, if you are still having trouble, maybe its an rsync issue and come 
back here for more help...


Best regards,
