        exit

        echo "not found pid file: ${pidfile}"
        exit

if [ $res == 1 ]; then
        if [ ! -e /tmp/$today ]; then
                echo "failed make directory: /tmp/${today}"
  exit
        fi

kill -HUP `cat ${pidfile}`

cd /tmp

if [ $res == 0 ]; then
        echo "backup successfully"
else
        echo "backup failed"

rm -Rf $today
exit
