Windows has some strange authentication concepts and logging in with a
key is not exactly the same as using a password, but I don't know
enough about it to help.   In any case if you get read access to the
path you are backing up you shouldn't have a complete failure.   I
normally run the cygwin ssh-host-config and ssh-user-config scripts
after installing cygwin ssh  but I've forgotten what they do.

You have some typos there - various spellings of backuppc and
/sygdrive should be /cygdrive.   Check those first, and that if you
log in over ssh you actually see  /usr/bin/rsync.exe installed as part
of cygwin.    It is also important that no messages are output when
ssh connects before rsync starts.
