linux自动运行rman增量备份脚本

这篇文章主要介绍了linux自动运行rman增量备份脚本，实现周日和周三凌晨1:00执行0级全库备份，周一、二、四、五、六凌晨1:30执行增量备份,需要的朋友可以参考下

一、增量备份脚本
0级备份脚本：红色部分为自定义的备份文件放置的目录

#script.:BackupFull.sh
#creater:xyh
#date:2014-03-08
#desc:backup full database datafile in archive with rman
#connect database
export ORACLE_BASE=/u01/app/oracle
export ORACLE_SID=orcl
export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
rman target/ << EOF_RMAN
run{
allocate channel c1 type disk;
backup incremental level 0 tag 'db0' format
'/home/oracle/RmanBackup/db0_%d_%T_%s' database include current controlfile;
sql 'alter system archive log current';
backup filesperset 5 format '/home/oracle/RmanBackup/cf0_%d_%T_%s' archivelog all delete input;
#filesperset 5表示备份集里面最多包含5个文件
delete noprompt obsolete;
release channel c1;
}
# end

1级备份脚本

复制代码代码如下:

	
	#script.:Incrl.sh

	#creater:xyh

	#date:2014-03-08

	#desc:backup full database datafile in archive with rman

	#connect database

	export ORACLE_BASE=/u01/app/oracle

	export ORACLE_SID=orcl

	export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1

	export PATH=$ORACLE_HOME/bin:$PATH

	rman target/ << EOF_RMAN

	run{

	allocate channel c1 type disk;

	backup incremental level 1 tag 'db1' format

	'/home/oracle/RmanBackup/db1_%d_%T_%s' database include current controlfile;

	sql 'alter system archive log current'; 

	backup filesperset 5 format '/home/oracle/RmanBackup/cf1_%d_%T_%s' archivelog all delete input; 

	#filesperset 5表示备份集里面最多包含5个文件  

	delete noprompt obsolete;

	release channel c1;

	}

	#end

二、使用linux的crontab设置自动执行备份

复制代码代码如下:

crontab -e

按Enter后，可以像vi编辑器一样输入下面内容

复制代码代码如下:

	
1 * * 0 /home/oracle/BackupFull.sh >>/home/oracle/BackupFull.log

1 * * 3 /home/oracle/BackupFull.sh >>/home/oracle/BackupFull.log

1 * * 1-2 /home/oracle/Incrl.sh >>/home/oracle/Incr.log

1 * * 4-6 /home/oracle/Incrl.sh >>/home/oracle/Incr.log

查看crontab内容：crontab -l
注：上面意思是把全库备份日志写到/home/oracle/BackupFull.log文件中，而增量备份日志写到/home/oracle/Incr.log中
