Yes, I know, in the same sense I was saying "provide" as another tool in the Wine environment.
Any tool in the Wine environment will be using Wine to run, negating the ability to use it for the purpose you describe. You need a native program to do this when Wine isn't running.
I still don't see why you couldn't use rsync for this...
