I've done something like this using a shell script.
Essentially the code goes like this:
if in_operating_window ; then
echo kill -HUP $$ | at $end_operating_window_time
exec rsync "$@"
else
echo $0 "$@" | at $start_operating_window_time
fi
as you can see, the script uses at(1) to resubmit itself if it's not
running during the operating window, otherwise it sets up an at job
that will send the script a SIGHUP (causing the running rsync to exit)
at the end of the operating window.
