linux 下crontab管理RMAN一周自动增量备份

编写各自对应的级别备份脚本 rmanbklevel_0.sh rmanbklevel_1.sh rmanbklevel_2.sh

在root身份下添加crontab任务计划
[root@oracle11gR2 ~]# crontab -e
59 19 * * 0 su - oracle -c /u01/scripts/rmanbklevel_0.sh 每周日19点59分0级备份
59 19 * * 1 su - oracle -c /u01/scripts/rmanbklevel_2.sh 每周一19点59分2级备份
59 19 * * 2 su - oracle -c /u01/scripts/rmanbklevel_2.sh 每周二19点59分2级备份
59 19 * * 3 su - oracle -c /u01/scripts/rmanbklevel_1.sh 每周三19点59分1级备份
59 19 * * 4 su - oracle -c /u01/scripts/rmanbklevel_2.sh 每周四19点59分2级备份
59 19 * * 5 su - oracle -c /u01/scripts/rmanbklevel_2.sh 每周五19点59分2级备份
59 19 * * 6 su - oracle -c /u01/scripts/rmanbklevel_2.sh 每周六19点59分2级备份
保存退出

[root@oracle11gR2 ~]# service crond restart //重启任务计划
