 顺便提一嘴： 
 
delete noprompt obsolete与delete obsolete区别
 
 
noprompt ：是不用提示，在shell脚本中不需要对发起的delete命令进行“yes or no”的确认。
 
 
 
 
 在crontab 中设置如下： 0 4 * * 5 sh /backup/scripts/oracle/oracle_rman_bak.sh 0 > /backup/archivelog/logs/rman.log 2>&1
 





 0 4 * * 2 sh /backup/scripts/oracle/oracle_rman_bak.sh 1 > /backup/archivelog/logs/rman.log 2>&1
 
 
 
 进行一周一次增量与0级备份。
