centos6.5下oracle自动备份删除指定天数的文件

第一步先做一个备份

#!/bin/sh

export ORACLE_BASE=/home/oracle/app

export ORACLE_HOME=$ORACLE_BASE/oracle/product/11.2.0/dbhome_1

export ORACLE_SID=orcl

export LD_LIBRARY_PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin

//注意是冒号

rq=`date '+%Y%M%D%H%M'`

/home/oracle/app/oracle/product/11.2.0/dbhome_1/bin/exp oracle/oracle@orcl12 owner=oracle file=/home/oracle/backup/oracleBack_$rq.dmp log=/home/oracle/backup/oracleBack_$rq.log

//压缩文件名

ordatabak=oracleBack_$rq.tar.gz

dmpbak=oracleBack_$rq.dmp

logbak=oracleBack_$rq.log

days=7

cd /home/oracle/backup

tar -zcvf  $ordatabak  $dmpbak $logbak

find "/home/oracle/backup" -type f -name "*.dmp" -exec rm {} \;

find "/home/oracle/backup" -type f -name "*.log" -exec rm {} \;

find "/home/oracle/backup" -type f -name "*.tar.gz" -mtime +$days  -exec  rm -rf {} \;



//这里需要注意 {} \;之间有空格   -mtime +$days之间有空格
