Oracle RMAN备份一例：

Solaris 10 + Oracle 11.2.0.3

Shell：csh

备份策略：周日0级备份,周一~周六1级备份,每6小时备份归档日志,每天清理历史文件夹.

--0级备份脚本：

#!/bin/csh
#db0 level backup
foldername=`date +%Y%m%d`
cd /oradata1/backup
if [ -d $foldername ]
then
        echo    ‘go on‘
else
        echo    ‘need mkdir‘
        mkdir $foldername
fi

set ORACLE_SID SHIRNOP
set ORACLE_BASE /opt/app/oracle/
set ORACLE_HOME /opt/app/oracle/product/11.2.0/dbhome_1/
set NLS_LANG "simplified chinese_china.ZHS16GBK"
set NLS_DATE_FORMAT "YYYY-MM-DD HH24:Mi:SS"
set PATH /bin:/usr/bin:/usr/local/bin:/usr/ucb:/usr/bin/csh:/etc:/opt/app/oracle/product/11.2.0/dbhome_1//bin:.

rman target /  log=/oradata1/backup/$foldername/full_LOG_%U.log << RMAN_BACKUP
run{
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 8 DAYS;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO ‘/oradata1/backup/$foldername/controlfile%F‘;
allocate channel c1 device type disk;
allocate channel c2 device type disk;
backup incremental level 0 tag ‘db0‘ database format ‘/oradata1/backup/$foldername/db0_%d_%T_%s‘ include current controlfile;
delete noprompt obsolete;
release channel c1;
release channel c2;
}
RMAN_BACKUP

--1级备份脚本：

#!/bin/csh
#db1 level backup
foldername=`date +%Y%m%d`
cd /oradata1/backup
if [ -d $foldername ]
then
        echo    ‘go on‘
else
        echo    ‘need mkdir‘
        mkdir $foldername
fi

set ORACLE_SID SHIRNOP
set ORACLE_BASE /opt/app/oracle/
set ORACLE_HOME /opt/app/oracle/product/11.2.0/dbhome_1/
set NLS_LANG "simplified chinese_china.ZHS16GBK"
set NLS_DATE_FORMAT "YYYY-MM-DD HH24:Mi:SS"
set PATH /bin:/usr/bin:/usr/local/bin:/usr/ucb:/usr/bin/csh:/etc:/opt/app/oracle/product/11.2.0/dbhome_1//bin:.

rman target /  log=/oradata1/backup/$foldername/incr_LOG_%U.log << RMAN_BACKUP
run{
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 8 DAYS;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO ‘/oradata1/backup/$foldername/controlfile%F‘;
allocate channel c1 device type disk;
allocate channel c2 device type disk;
backup incremental level 1 tag ‘db1‘ database format ‘/oradata1/backup/$foldername/db1_%d_%T_%s‘ include current controlfile;
delete noprompt obsolete;
release channel c1;
release channel c2;
}
RMAN_BACKUP

--归档备份

#!/bin/csh
#arch backup
foldername=`date +%Y%m%d`
cd /oradata1/backup
if [ -d $foldername ]
then
        echo    ‘go on‘
else
        echo    ‘need mkdir‘
        mkdir $foldername
fi

set ORACLE_BASE /opt/app/oracle/
set ORACLE_HOME /opt/app/oracle/product/11.2.0/dbhome_1/
set ORACLE_SID SHIRNOP
set NLS_LANG "simplified chinese_china.ZHS16GBK"

set PATH /bin:/usr/bin:/usr/local/bin:/usr/ucb:/usr/bin/csh:/etc:/opt/app/oracle/product/11.2.0/dbhome_1//bin:.

rman target /  log=/oradata1/backup/$foldername/arch_LOG_%U.log << RMAN_BACKUP
run{
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 8 DAYS;
allocate channel c1 device type disk;
allocate channel c2 device type disk;
sql ‘alter system archive log current‘;
backup archivelog all delete input format ‘/oradata1/backup/$foldername/arch_%d_%T_%s‘;
release channel c1;
release channel c2;
}
crosscheck archivelog all;
delete expired archivelog all;
RMAN_BACKUP

--系统级别删除过期备份的空文件夹

#!/bin/bash
#del old folders
cd /oradata1/backup
find . -mtime +10 | xargs rm -rf

--crontab调度
crontab -l
