# 腳本功能:oracle備份腳本
# 執行方法:1、第一次執行需要root用戶執行，腳本會以詢問的方式創建備份目錄和相關參數
# 2、腳本會自動寫入crontab調度裡面定時執行，crontab設置是在第一次執行的時候自動添加的

接下來給大家介紹linux oracle自動備份腳本
1、備份腳本：
#!/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、添加到任務調度
crontab -u oracle -e
* 3 * * * /home/bakup/bakup.sh
即每天凌晨3點進行備份
如需每天備份多次，可設置不同時間段備份：
例如：* 3,13,18 * * * /home/bakup/bakup.sh，即每天3點、13點、18點進行備份。
說明：文件備份目錄，用戶oracle必須有更改權限，否則無法備份。
