windows 下RMAN備份腳本實例

環境：windows server 2008   +  oracle 10g R2 32bit

例一：

徹底備份：

一、建立文件 full_backup.sql ，內容以下

run{
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14 DAYS;
allocate channel d1 type disk;   //開啓多個通道
allocate channel d2 type disk;
allocate channel d3 type disk;
allocate channel d4 type disk;
backup current controlfile format 'h:\rman_backup\ctl_%d_%s_%p_%u.bak';   //備份當前控制文件，並指定備份文件路徑
backup as compressed backupset full database format 'h:\rman_backup\full_%d_%s_%p_%u.bak'; //全庫備份，並指定備份文件存放路徑
sql 'alter system archive log current';   //切換歸檔日誌
backup archivelog all format 'h:\rman_backup\log_%d_%s_%p_%u.bak' delete all input;  //備份全部歸檔日誌
release channel d1; //釋放通道
release channel d2;
release channel d3;
release channel d4;
report obsolete;   //報告過時或無效的備份
crosscheck backup;  //交叉檢查備份
delete noprompt expired backup;  //刪除過時的備份，不需交互確認
delete noprompt obsolete; //刪除無效的備份，不需交互確認
delete noprompt ARCHIVELOG until time 'SYSDATE-14';  //刪除14天前的備份歸檔日誌
}

二、新建bat文件full_backup.bat，內容以下：

rman target / cmdfile='h:\rman_backup\script\full_backup.sql' log='h:\rman_backup\script\log\full_backup.log' append

三、把上述建立的兩個文件存放在相對應的路徑，而後在系統新建計劃任務執行full_backup.bat文件便可。

例二：

增量備份，備份計劃以下圖所示：

一、建立增量0級備份文件level0_backup.sql，內容以下：

run{
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS;
allocate channel d1 type disk;
allocate channel d2 type disk;
backup incremental level=0 database include current controlfile format 'h:\rman_backup\level0_%d_%s_%p_%u.bak' plus archivelog format 'h:\rman_backup\log_%d_%s_%p_%u.bak';
release channel d2;
release channel d1;
report obsolete;
crosscheck backup;
delete noprompt expired backup;
delete noprompt obsolete;
delete noprompt ARCHIVELOG until time 'SYSDATE-30';  //刪除30天前的歸檔日誌
}

二、建立增量0級備份bat文件level0_backup.bat,內容以下：

rman target / cmdfile='h:\rman_backup\script\level0_backup.sql' log='h:\rman_backup\script\log\level0_backup.log' append

三、建立增量1級備份文件level1_backup.sql，內容以下：

run{
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS;
allocate channel d1 type disk;
allocate channel d2 type disk;
backup incremental level=1 database include current controlfile format 'h:\rman_backup\level1_%d_%s_%p_%u.bak' plus archivelog format 'h:\rman_backup\log_%d_%s_%p_%u.bak';
release channel d2;
release channel d1;
}

四、建立增量1級備份bat文件level1_backup.bat,內容以下：

rman target / cmdfile='h:\rman_backup\script\level1_backup.sql' log='h:\rman_backup\script\log\level1_backup.log' append

五、建立增量1c級備份文件level1c_backup.sql，內容以下：

run{
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS;
allocate channel d1 type disk;
allocate channel d2 type disk;
backup incremental level=1 cumulative database include current controlfile format 'h:\rman_backup\level1c_%d_%s_%p_%u.bak' plus archivelog format 'h:\rman_backup\log_%d_%s_%p_%u.bak';
release channel d1;
release channel d2;
report obsolete;
crosscheck backup;
delete noprompt expired backup;
delete noprompt obsolete;
delete noprompt ARCHIVELOG until time 'SYSDATE-30';
}

六、建立增量1級備份bat文件level1c_backup.bat,內容以下：

rman target / cmdfile='h:\rman_backup\script\level1c_backup.sql' log='h:\rman_backup\script\log\level1c_backup.log' append

按上圖計劃在系統中創建相對應的計劃任務執行上述bat文件便可。
