================== RMAN一周典型备份方案 ===============
1.星期天晚上 -level 0 backup (全备份)
2.星期一晚上 -level 2 backup
3.星期二晚上 -level 2 backup
4.星期三晚上 -level 1 backup
5.星期四晚上 -level 2 backup
6.星期五晚上 -level 2 backup
7.星期六晚上 -level 2 backup
如果星期二需要恢复的话，只需要1+2,
如果星期四需要恢复的话，只需要1+4,
如果星期五需要恢复的话，只需要1+4+5,
如果星期六需要恢复的话，只需要1+4+5+6.
自动备份:备份脚本+crontab
bakl0
bakl1
bakl2
配置：
1: mkdir -p /u01/app/oracle/rmanbak/scripts/ (放备份脚本目录)
2: mkdir -p /u01/app/oracle/rmanbak/logs/ (放日志目录)
3: mkdir -p /u01/app/oracle/rmanbak/bak/ (放备份文件的目录)
4: crontab -e -u root
