1、数据库设置为归档方式
shutdown immediate；
startup mount；
alter database archivelog；
alter database open；
archive log list；
2、数据库的备份脚本
db_full_backup.sh ：数据库全备脚本
db_l0_backup.sh ：数据库0级备份脚本
db_l1_backup.sh ：数据库1级备份脚本
ftp.sh ：数据FTP上传脚本
ftp_del.sh ：数据FTP清理脚本
rman_bak.sh ：数据备份主程序
3、备份原理
每周1、3、6进行0级备份
每周日、2、4、5进行1级备份
备份文件上传到FTP服务器
FTP服务器每周清理一次，但是清理后将周六和周日的备份进行保留(6.bak和0.bak)
所有工作防暑crontab中自动执行备份
4、备份目录含义
arc ：数据库归档目录
rmanbak ：数据库备份文件的保存目录
rmanscripts ：数据库脚本存放路径
5、FTP目录
ftp上必须手动建立目录
L0：
---1
---3
---6
---6.bak
L1：
---2
---4
---5
---0
---0.bak
