一个典型的增量备份案例如下：
- 星期天晚上 -levle 0 backup performed
- 星期一晚上 -levle 2 backup performed
- 星期二晚上 -levle 2 backup performed
- 星期三晚上 -levle 1 backup performed
- 星期四晚上 -levle 2 backup performed
- 星期五晚上 -levle 2 backup performed
- 星期六晚上 -levle 2 backup performed
- 自动备份：备份脚本 +crontab

- 执行脚本：
rman target / msglog=/home/oracle/RmanBackup/bak_lv_0.log cmdfile=/home/oracle/BackupScripts/bak_lv_0
rman target / msglog=/home/oracle/RmanBackup/bak_lv_1.log cmdfile=/home/oracle/BackupScripts/bak_lv_1
rman target / msglog=/home/oracle/RmanBackup/bak_lv_2.log cmdfile=/home/oracle/BackupScripts/bak_lv_2
- crontab -e oracle
00 03 * * 0 /home/oracle/BackupScripts/bak_lv_0 >> /home/oracle/RmanBackup/bak_lv_0.log 00 03 * * 1,2,4,5,6 /home/oracle/BackupScripts/bak_lv_2 >> /home/oracle/RmanBackup/bak_lv_2.log 00 03 * * 3 /home/oracle/BackupScripts/bak_lv_1 >> /home/oracle/RmanBackup/bak_lv_1.log
注意:
1、上述自动执行脚本需要在root用户下执行，执行命令:crontab -e -u oracle，编辑完成，保存退出；
2、重新启动一下crontab命令即可：service crond restart
