以前在博客里面介绍了RMAN备份脚本一列分享，通过RMAN备份到本地路径，然后通过FTP将备份文件上传到FTP服务器。 下面简单介绍另外一例RMAN备份解决方案，下面是我简单画的一个图（很少画图，感觉有点粗制滥造）。
首先将数据库备份到本地服务器的一个目录下（目录是按日期格式生成,本地备份保留周期视存储情况而定.一般一天即可）。
然后将备份文件通过Symantec Backup Exec 2012 Agent 将本地备份上传到磁带设备（容灾备份,磁带备份保留90天）。
最后清理本地备份路径下的备份。
如上所示，只有三个步骤，整体思路非常简单，下面介绍一下实施的具体脚本
首先介绍一下备份脚本backup_db_xxxx.sh （注意xxx为数据库实例名称，脚本里面很多xxx需要根据具体场景进行替换，例如实例名称、邮件地址等）

backup_db_xxx.rcv 文件其实RMAN的命令文件(backup_db_xxxx.sh 里面调用)。如下所示
1: run {
2: CONFIGURE RETENTION POLICY TO REDUNDANCY 2; # default
3: CONFIGURE BACKUP OPTIMIZATION ON;
4: CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
5: CONFIGURE CONTROLFILE AUTOBACKUP ON;

9: CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
10: CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/u04/backup/backupsets/ora_df%t_s%s_s%p';
11: CONFIGURE MAXSETSIZE TO UNLIMITED; # default
12: CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
13: CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
14: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
15: sql 'alter system archive log current';
16: backup as compressed backupset database plus archivelog delete input;
17: copy current controlfile to '/u04/backup/backupsets/controlfile.copy';
18: }
19: exit
delete_obj_xxxx.sh 文件如下所示：

31: #REM - BACKUP SECTION -
32: echo $BACKUP_FULL_LOG
33: rman target / $CATALOG cmdfile=/u04/backup/scripts/delete_ob_xxx.rcv log=$BACKUP_FULL_LOG
/u04/backup/scripts/delete_ob_xxx.rcv文件为RMAN的cmdfile，如下所示
1: run {
2: CONFIGURE RETENTION POLICY TO REDUNDANCY 2; # default
3: CONFIGURE BACKUP OPTIMIZATION ON;
4: CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
5: CONFIGURE CONTROLFILE AUTOBACKUP ON;

14: CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
15: sql 'alter system archive log current';
16: delete obsolete;
17: }
然后再crontab作业里面配置作业
15 00 * * * /u04/backup/scripts/backup_db_xxx.sh >/dev/null 2>&1
00 08 * * * /u04/backup/scripts/delete_ob_xxx.sh >/dev/null 2>&1
也许会有人问，不是还有Symantec Backup Exec Agent 将备份文件上带吗，其实关于这个，首先需要在Linux服务器安装Symantec Backup Exec 2012 Agent，这个可以参考我博客Symantec Backup Exec 2012 Agent For Linux安装。在配置文件指定Symantec Backup Exec Server，然后只需要在服务器设定一个作业定时备份文件即可。感觉没有啥可以说的。
