I found a thread, https://cygwin.com/ml/cygwin/2015-04/msg00008.html,
from last year where Corinna suggests the following (which works for her; she notes YMMV)
        robocopy C:\cygwin64 F:\cygwin64 /e /purge /z /copyall /sl
On Win7, I'm on a old cygwin installation (thought I'd copy to more spacious disk before updating) I tried this command after ssh to an admin account, but the command terminates with

where
    $ ls -l ssh_host_dsa_key

I don't know much about windows. Any ideas on how to get this to work?

Run robocopy as admin from an elevated command shell (bash or cmd) with Administrator privileges.

Simply running as admin doesn't solve the problem.

    $ robocopy C:/cygwin64 F:/cygwin64 -e -purge -z -copyall -sl

    ....

    $ id
uid=1000(erra) gid=513(None) groups=513(None),544(Administrators),545(Users),1007(HomeOffice)

Try from elevated Command Prompt (Admin) with expected path delimiters and switch chars:
    > robocopy C:\cygwin64 F:\cygwin64 /e /purge /z /copyall /sl
I've had success with:
    ... /s /copyall /xj /sl /mt:8 /r:0 /w:0 /ndl /nfl /np
but YMMV

It is elevated, AFAICT. That's the "....,544(Administrators),..." in the id command output. BTW, Robocopy seems to accept shellish syntax (saw a note in some docs) and have tried both ways.
