1. 建备份目录 oradataback，2级目录archback（放归档日志）、rmanscripts（备份脚本），
在rmanscripts下面建 rmanlevel0.sh rmanlevel1.sh rmanlevel2.sh 文件：
mkdir oradataback
--home/oracle/app/oradataback
chmod 775 oradataback
chown -R oracle:oinstall /home/oracle/app/oradataback
touch rmanlevel0.sh rmanlevel1.sh rmanlevel2.sh
赋权同上
2. vi 编辑3个文件：
0级备份文件：
--rmanlevel0.sh--
#!/bin/sh
source ~/.bash_profile
# set porfile_env
export ORACLE_SID=eytdbs # rman level0 backup
rman log='/home/oracle/app/oradataback/db_rman0.log' append <<EOF
connect target /;
run
{
allocate channel c1 type disk;
#allocate channel c2 type disk;
backup as compressed backupset incremental level=0 database format '/home/oracle/app/oradataback/db_level0_%T_%U' tag='level0';
sql 'alter system archive log current';
backup archivelog all format '/home/oracle/app/oradataback/archback/db_arch_%T_%U' delete input;
release channel c1;
#release channel c2;
}
EOF
1级备份文件：
--rmanlevel1.sh--
#!/bin/sh
source ~/.bash_profile
# set porfile_env
export ORACLE_SID=eytdbs # rman level1 backup
rman log='/home/oracle/app/oradataback/db_rman1.log' append <<EOF
connect target /;
run
{
allocate channel c1 type disk;
#allocate channel c2 type disk;
backup incremental level= 1 database format '/home/oracle/app/oradataback/db_level1_%T_%U' tag='level1';
sql 'alter system archive log current';
backup archivelog all format '/home/oracle/app/oradataback/archback/db_arch_%T_%U' delete input;
release channel c1;
#release channel c2;
delete noprompt obsolete; # 删除过期的备份
}
EOF
2级备份文件：
--rmanlevel2.sh--
#!/bin/sh
source ~/.bash_profile
# set porfile_env
export ORACLE_SID=eytdbs # rman level0 backup
rman log='/home/oracle/app/oradataback/db_rman2.log' append <<EOF
connect target /;
run
{
allocate channel c1 type disk;
#allocate channel c2 type disk;
backup incremental level=2 database format '/home/oracle/app/oradataback/db_level2_%T_%U' tag='level2';
sql 'alter system archive log current';
backup archivelog all format '/home/oracle/app/oradataback/archback/db_arch_%T_%U' delete input;
release channel c1;
#release channel c2;
}
EOF
#说明：在oracle用户下手动运行脚本的命令：sh rmanlevel2.sh
3. 加自动运行任务：
在root下设置，用vi编辑： #crontab -e
0 2 1 * * su – oracle -c /home/oracle/app/oradataback/rmanscripts/rmanlevel0.sh //每月1日2：00运行 0级备份
0 2 * * 0 su – oracle -c /home/oracle/app/oradataback/rmanscripts/rmanlevel1.sh //每周日2：00运行 1级备份
0 2 * * 1-6 su – oracle -c /home/oracle/app/oradataback/rmanscripts/rmanlevel2.sh //每周一周六2:00运行 2级增量备份
--查看添加的任务： crontab -l
--crontab的格式：
minutes|hours|day of month|month|day of week|
--启动crond：
/sbin/service crond start //启动服务
/sbin/service crond stop //关闭服务
/sbin/service crond restart //重启服务
/sbin/service crond reload //重新载入配置
4. 测试结果：
可以自动运行，能成功的备份数据。
--附加一个ftp.sh文件：
#!/bin/sh
cd /home/oracle/app/oradata #本地目录
tar -czf oradata`date +%Y%m%d`_217.tar.gz /home/oracle/app/oradata/
cd /home/oracle/app/fast_recovery_area/eytdbs #本地目录
tar -czf oralog`date +%Y%m%d`_217.tar.gz /home/oracle/app/fast_recovery_area/eytdbs/
#登陆远端机器
sftp oracle/@10.1.4.200 << EOF
cd /home/oracle #远端目录
put /home/oracle/app/oradata/oradata`date +%Y%m%d`_217.tar.gz
put /home/oracle/app/fast_recovery_area/eytdbs/oralog`date +%Y%m%d`_217.tar.gz
quit
EOF
