export BAKUPTIME=`date +%Y%m%d%H%M%S`

mkdir -p $DATA_DIR
mkdir -p $LOGS_DIR

echo "Starting bakup..."
echo "Bakup file path $DATA_DIR/$BAKUPTIME.dmp"
exp hxsource/admin@ORCL file=$DATA_DIR/$BAKUPTIME.dmp log=$LOGS_DIR/$BAKUPTIME.log

echo "Delete the file bakup before 7 days..."
rm -rf $DATA_DIR/$DELTIME*.dmp
rm -rf $LOGS_DIR/$DELTIME*.log
echo "Delete the file bakup successfully. "

echo "Bakup completed."
