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
