Oracle RMAN 备份一例：

Solaris 10 + Oracle 11.2.0.3

Shell：csh, 安装有 bash, 脚本调用 bash

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/bash
#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
 
export ORACLE_BASE=/opt/app/oracle/
export ORACLE_HOME=/opt/app/oracle/product/11.2.0/dbhome_1/
export ORACLE_SID=SHIRNOP
export NLS_LANG="simplified chinese_china.ZHS16GBK"
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:Mi:SS"
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32
export PATH=/bin:/usr/bin:/usr/ucb:/etc:$ORACLE_HOME/bin:.
 
rman target /  log=/oradata1/backup/$foldername/full_LOG.log << RMAN_BACKUP
run{
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/oradata1/backup/$foldername/controlfile%F';
allocate channel c1 device type disk;

delete noprompt obsolete;
release channel c1;
release channel c2;
release channel c3;
release channel c4;
}

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