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."

而後使用crontab命令添加定時任務便可。
