Linux 平台下 RMAN 全备和增量备份 shell 脚本

http://blog.csdn.net/tianlesoftware/archive/2010/07/16/5740630.aspx

在执行脚本之前，先修改几个参数值：

1. DB 参数：

修改控制文件的保存时间，从默认的7天改成14天

SQL> show parameter control

SQL> alter system set control_file_record_keep_time=14 scope=both;

2. RMAN 参数：

开启控制文件的自动备份，开启之后在数据库备份或者数据文件（比如添加数据文件）有修改的时候都会自动备份控制文件和spfile文件。

RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;

RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

3. 备份策略根据自己的系统决

我这里是周日做0级备份。周四1级备份，其他2级备份。

4. 备份脚本如下：
