 Oracle数据库RMAN的自动备份脚本 
 操作系统：Linux 
 数据库：oracle9.2.0.4 
 1、数据库设置为归档方式 
 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
