Hmm! It didn't seem that obvious to me.

I tested with "-rltgoDvzi" and it did NOT attempt to backup any files AND it DID fail to hard link files. Great insight. > A better solution would be to have the Windows machine push the files to > an rsync daemon running on the Linux server. Am I still using cygwin for this or how do I "push"? I should mention that I hope to backup several PC's to their users' area of the samba machine.

BTW1, I have to say that I've read a lot of "expert" replies on forums and I've never seen anyone who has carefully read the question and replied with so much detail and precision as you. Thank you! BTW2, I'm not sure that I've replied correctly to this list. Let me know if I should be using another method. Thanks again, Link McGinnis -- No virus found in this outgoing message.
