# 2、脚本会自动写入crontab调度里面定时执行，crontab设置是在第一次执行的时候自动添加的

接下来给大家介绍linux oracle自动备份脚本

1、备份脚本：

#!/bin/sh 
export ORACLE_BASE=/home/oracle 
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1 
export ORACLE_SID=orcl 
export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin 
export DATA_DIR=/home/bakup/data 
export LOGS_DIR=/home/bakup/logs 
export DELTIME=`date -d "7 days ago" +%Y%m%d` 
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 shop/lyisABC0987@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."

2、添加到任务调度

crontab -u oracle -e
* 3 * * * /home/bakup/bakup.sh
即每天凌晨3点进行备份
如需每天备份多次，可设置不同时间段备份：
例如：* 3,13,18 * * * /home/bakup/bakup.sh，即每天3点、13点、18点进行备份。
说明：文件备份目录，用户oracle必须有更改权限，否则无法备份。
