以前在博客裡面介紹了RMAN備份腳本一列分享，通過RMAN備份到本地路徑，然後通過FTP將備份文件上傳到FTP服務器。 下面簡單介紹另外一例RMAN備份解決方案，下面是我簡單畫的一個圖（很少畫圖，感覺有點粗制濫造）。
首先將數據庫備份到本地服務器的一個目錄下（目錄是按日期格式生成,本地備份保留周期視存儲情況而定.一般一天即可）。
然後將備份文件通過Symantec Backup Exec 2012 Agent 將本地備份上傳到磁帶設備（容災備份,磁帶備份保留90天）。
最後清理本地備份路徑下的備份。
如上所示，只有三個步驟，整體思路非常簡單，下面介紹一下實施的具體腳本
首先介紹一下備份腳本backup_db_xxxx.sh （注意xxx為數據庫實例名稱，腳本裡面很多xxx需要根據具體場景進行替換，例如實例名稱、郵件地址等）

33: rman target / $CATALOG cmdfile=/u04/backup/scripts/delete_ob_xxx.rcv log=$BACKUP_FULL_LOG
/u04/backup/scripts/delete_ob_xxx.rcv文件為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

16: delete obsolete;
17: }
然後再crontab作業裡面配置作業
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
也許會有人問，不是還有Symantec Backup Exec Agent 將備份文件上帶嗎，其實關於這個，首先需要在Linux服務器安裝Symantec Backup Exec 2012 Agent，這個可以參考我博客Symantec Backup Exec 2012 Agent For Linux安裝。在配置文件指定Symantec Backup Exec Server，然後只需要在服務器設定一個作業定時備份文件即可。感覺沒有啥可以說的。
