Alireza,
Believe it or not, your best bet at this time is still good old Robocopy. We've had some issues with Robocopy not copying permissions correctly on the newer versions of the tool, but this is about your best bet. There are many tools available, both free and purchased. One of the better purchased tools we've found is called Beyond Compare, but it does not copy permissions. There is a free (i.e. unsupported) tool from Microsoft called RichCopy, but it sometimes has issues with permissions as well.
Long story short, there is no silver bullet. You just have to find what works for you.
