Oracle自动备份脚本

废话不多说了，直接给大家贴代码了，具体代码如下所示：

#!/bin/sh
#******************************************************************
# File: oraclebak.sh
# Creation Date: 2014/1/22 17:57:32
# Last Modified: 2014/1/22 17:57:34
# 脚本功能:oracle备份脚本
# 执行方法:1、第一次执行需要root用户执行，脚本会以询问的方式创建备份目录和相关参数
# 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。
