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
复制代码 代码如下:
#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:
0 1 * * 0 /home/oracle/BackupFull.sh /home/oracle/BackupFull.log
0 1 * * 3 /home/oracle/BackupFull.sh /home/oracle/BackupFull.log
30 1 * * 1-2 /home/oracle/Incrl.sh /home/oracle/Incr.log
30 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
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
