LINUX上RMAN自动备份脚本

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
