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 backupfoldername=`date +%Y%m%d`cd /oradata1/backupif [ -d $foldername ]then        echo    ‘go on‘else        echo    ‘need mkdir‘        mkdir $foldernamefiset ORACLE_SID SHIRNOPset ORACLE_BASE /opt/app/oracle/set ORACLE_HOME /opt/app/oracle/product/11.2.0/dbhome_1/set NLS_LANG "simplified chinese_china.ZHS16GBK"set NLS_DATE_FORMAT "YYYY-MM-DD HH24:Mi:SS"set PATH /bin:/usr/bin:/usr/local/bin:/usr/ucb:/usr/bin/csh:/etc:/opt/app/oracle/product/11.2.0/dbhome_1//bin:.rman target /  log=/oradata1/backup/$foldername/full_LOG_%U.log << RMAN_BACKUPrun{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：

--系统级别删除过期备份的空文件夹
#!/bin/bash#del old folderscd /oradata1/backupfind . -mtime +10 | xargs rm -rf
--crontab调度
