samba rename bug - solution?

[Bryan O'Neal]

I used rsync from windows to my CentOS back up server and it copied the
permissions, including the advanced ACLs just fine.  I believe I used
something like  -arvtzAogpX for my attribute list.  Rsync is a very capable
program even on windows.

I'm not even sure that using rsync on cygwin respects NT permissions at all
and would probably suggest that he use robocopy.exe for copying files and
retaining permissions but I was concentrating on answering the questions he
was asking.
