注 level 0 全备份；level 2 增量备份； level 1  差量备份 参照http://www.itpub.net/658332.html

 

自动备份： 备份脚本+ linux下的crontab

在redhat linux 的 u01/rmanbak/script/目录下新建下面文件

bakl0 文件

run{

allocate channel c1 type disk;

backup incremental level 0 format "/u01/rmanbak/inc0_%u_%T" tag monday_inc0 database;

release channel c1;

}

bakl1 文件

run{

allocate channel c1 type disk;

backup incremental level 1 format "/u01/rmanbak/inc1_%u_%T" tag monday_inc0 database;

release channel c1;

}

bakl2 文件

run{

allocate channel c1 type disk;

backup incremental level 2 format "/u01/rmanbak/inc2_%u_%T" tag monday_inc0 database;

release channel c1;

}

执行脚本：

rman target / msglog=/u01/rmanbak/bakl0.log cmdfile=/u01/rmanbak/script/bakl0

rman target / msglog=/u01/rmanbak/bakl1.log cmdfile=/u01/rmanbak/script/bakl1

rman target / msglog=/u01/rmanbak/bakl2.log cmdfile=/u01/rmanbak/script/bakl2

 

编辑oracle用户自动执行计划

crontab 命令用法参照 ： http://blog.youkuaiyun.com/yuanfeiyan/archive/2007/10/15/1825288.aspx

crontab -e -u oracle

 

内容：

30 23 * * 0 rman target / msglog=/u01/rmanbak/bakl0.log cmdfile=/u01/rmanbak/script/bakl0

30 23 * * 1 rman target / msglog=/u01/rmanbak/bakl0.log cmdfile=/u01/rmanbak/script/bakl2

30 23 * * 2 rman target / msglog=/u01/rmanbak/bakl0.log cmdfile=/u01/rmanbak/script/bakl2

30 23 * * 3 rman target / msglog=/u01/rmanbak/bakl0.log cmdfile=/u01/rmanbak/script/bakl1

30 23 * * 4 rman target / msglog=/u01/rmanbak/bakl0.log cmdfile=/u01/rmanbak/script/bakl2

30 23 * * 5 rman target / msglog=/u01/rmanbak/bakl0.log cmdfile=/u01/rmanbak/script/bakl2

30 23 * * 6 rman target / msglog=/u01/rmanbak/bakl0.log cmdfile=/u01/rmanbak/script/bakl2

 

注释：30 23 * * 0 表示 30分 23点 *日期 *月 0星期天

-e 编辑用户的Crontab文件

 

 

重启crontab 命令 ： service cronb restart

 

如果不能执行。原因1、脚本是否是可执行脚本。2、oracle环境变量问题。 解决办法是在写个shall让crontab调用例如

a1、bakup1.sh  
rq=`date '+%y%m%d'`; 
export ORACLE_HOME=/opt/app/oracle/9.2.0;
export ORACLE_SID=zhang;
export ORACLE_BASE=/opt/app/oracle;
export PATH=$ORACLE_HOME/bin;$PATH;
/opt/app/oracle/9.2.0/bin/rman target / msglog=/home/oracle/oraBak/autoBak/bakup1_$rq.log cmdfile=/home/oracle/oraBak/script/bakup2
