Actually, yes it does ... at least the way I suggested. The whole point of an in-place rsync is it does a comparison, and only writes the data IF IT CHANGES. So a "change it to itself" change will be detected and ignored by rsync (okay, it may well update the inode, but then that HAS changed :-) Cheers, Wol
