probably not the "canonical" way, but still works:
I have a script in /etc/init.d/mystuff for a similar task, that looks
basically like

case "$1" in
    start)
        printf "/usr/sbin/ntpdate-debian -s -b -p 8 -u de.pool.ntp.org" | at now + 2 minutes
        ;;
    stop)
        RUNL=`/sbin/runlevel`
        case ${RUNL:2:3} in 0)
            /usr/local/sbin/sys-backup;;
        esac
        ;;
esac

Regards

Michael
