各位同学知道Oracle数据库RMAN如何自动备份脚本嘛?下面我为大家整理了关于Oracle数据库RMAN的自动备份脚本文章，希望能为你提供帮助：

1、数据库设置为归档方式

2、数据库的备份脚本

db_full_backup.sh ：数据库全备脚本

db_l0_backup.sh ：数据库0级备份脚本

db_l1_backup.sh ：数据库1级备份脚本

：数据FTP上传脚本

ftp_del.sh ：数据FTP清理脚本

rman_bak.sh ：数据备份主程序

3、备份原理

每周1、3、6进行0级备份

每周日、2、4、5进行1级备份

备份文件上传到FTP服务器

FTP服务器每周清理一次，但是清理后将周六和周日的备份进行保留(6.bak和0.bak)

所有工作防暑crontab中自动执行备份

4、备份目录含义

arc ：数据库归档目录

rmanbak ：数据库备份文件的保存目录

rmanscripts ：数据库脚本存放路径

5、FTP目录

ftp上必须手动建立目录

L0：

---1

---3

---6

---6.bak

L1：

---2

---4

---5

---0

---0.bak

rman_bak.sh脚本主程序

oracle怎么用rman脚本进行备份

Oracle数据库中rman备份脚本非常实用

查询字符集

SQL select * from nls_database_parameters;

NLS_CHARACTERSET

AL32UTF8

备份时字符集很重要，不然会出乱码

一、0级备份（全备）红色是要修改的，根据个人的存放位置。

[oracle@oracle122 script]$ cat db_bak0.rman

run

{

configure retention policy to recovery window of 8 days;

configure controlfile autobackup on;

configure controlfile autobackup format for device type disk to '/home/oracle/rmanbak/%F';

allocate channel ch1 device type disk format '/home/oracle/rmanbak/inc0_%d_%s_%p_%u_%T';

backup incremental level 0 tag='level 0' database skip inaccessible filesperset 10 plus archivelog filesperset 20;

release channel ch1;

}

allocate channel for maintenance device type disk;

crosscheck backup;

delete noprompt expired backup;

delete noprompt obsolete;

delete noprompt archivelog until time 'sysdate-30';

0级运行脚本

[oracle@oracle122 script]$ cat exec_0_level.sh

ORACLE_HOSTNAME=oracle122; export ORACLE_HOSTNAME

ORACLE_BASE=/u01/app; export ORACLE_BASE

ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1; export ORACLE_HOME

ORACLE_SID=orcl; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

PATH=/usr/sbin:$PATH; export PATH

PATH=$ORACLE_HOME/bin:$PATH; export PATH

export DATE=$(date +%Y_%m_%d)

export NLS_LANG="Simplified Chinese_china".AL32UTF8

/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/sys_admin cmdfile /home/oracle/rmanbak/script/db_bak0.rman log /home/oracle/rmanbak/script/log/rman_$DATE.log append

二、1级备份（增量）

[oracle@oracle122 script]$ cat db_bak1.rman

run

{

configure retention policy to recovery window of 8 days;

configure controlfile autobackup on;

configure controlfile autobackup format for device type disk to '/home/oracle/rmanbak/%F';

allocate channel ch1 device type disk format '/home/oracle/rmanbak/inc1_%d_%s_%p_%u_%T';

backup incremental level 1 tag='level 1' database skip inaccessible filesperset 10 plus archivelog filesperset 20;

release channel ch1;

}

allocate channel for maintenance device type disk;

crosscheck backup;

delete noprompt expired backup;

delete noprompt obsolete;

delete noprompt archivelog until time 'sysdate-30';

1级运行脚本

[oracle@oracle122 script]$ cat exec_1_level.sh

ORACLE_HOSTNAME=oracle122; export ORACLE_HOSTNAME

ORACLE_BASE=/u01/app; export ORACLE_BASE

ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1; export ORACLE_HOME

ORACLE_SID=orcl; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

PATH=/usr/sbin:$PATH; export PATH

PATH=$ORACLE_HOME/bin:$PATH; export PATH

export DATE=$(date +%Y_%m_%d)

export NLS_LANG="Simplified Chinese_china".AL32UTF8

/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/sys_admin cmdfile /home/oracle/rmanbak/script/db_bak1.rman log /home/oracle/rmanbak/script/log/rman_$DATE.log append

三、2级备份（从0级追加到现在的备份）

[oracle@oracle122 script]$ cat db_bak2.rman

run

{

configure retention policy to recovery window of 8 days;

configure controlfile autobackup on;

configure controlfile autobackup format for device type disk to '/home/oracle/rmanbak/%F';

allocate channel ch1 device type disk format '/home/oracle/rmanbak/inc2_%d_%s_%p_%u_%T';

backup incremental level 2 tag='level 2' database skip inaccessible filesperset 10 plus archivelog filesperset 20 delete all input;

release channel ch1;

}

allocate channel for maintenance device type disk;

crosscheck backup;

delete noprompt expired backup;

delete noprompt obsolete;

2级运行脚本

[oracle@oracle122 script]$ cat exec_2_level.sh

ORACLE_HOSTNAME=oracle122; export ORACLE_HOSTNAME

ORACLE_BASE=/u01/app; export ORACLE_BASE

ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1; export ORACLE_HOME

ORACLE_SID=orcl; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

PATH=/usr/sbin:$PATH; export PATH

PATH=$ORACLE_HOME/bin:$PATH; export PATH

export DATE=$(date +%Y_%m_%d)

export NLS_LANG="Simplified Chinese_china".AL32UTF8

/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/sys_admin cmdfile /home/oracle/rmanbak/script/db_bak2.rman log /home/oracle/rmanbak/script/log/rman_$DATE.log append

定时备份星期天为0级全备，星期三为2级备份，星期一，星期二，星期四，星期五，星期六为1级增量备份晚上11点开始备份

[oracle@oracle122 script]$ crontab -l

* 23 * * 0 /home/oracle/rmanbak/script/exec_0_level.sh

* 23 * * 1 /home/oracle/rmanbak/script/exec_1_level.sh

* 23 * * 2 /home/oracle/rmanbak/script/exec_1_level.sh

* 23 * * 3 /home/oracle/rmanbak/script/exec_2_level.sh

* 23 * * 4 /home/oracle/rmanbak/script/exec_1_level.sh

* 23 * * 5 /home/oracle/rmanbak/script/exec_1_level.sh

* 23 * * 6 /home/oracle/rmanbak/script/exec_1_level.sh
