RMAN 备份与恢复深入解析（二）

發(fā)布時(shí)間：2025/5/22 编程问答 18 豆豆

生活随笔收集整理的這篇文章主要介紹了 RMAN 备份与恢复深入解析（二）小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

2.用示例說(shuō)明兩種增量備份的差別

大家早上好，早上的陽(yáng)光真是明媚，新的一天即將開始，下面我們來(lái)研究研究增量備份的奧妙：）

Incremental增量備份：中心思想就是減少備份的數(shù)據(jù)量，我們不需要在從頭開始備份了，只需要備份自上次已備份之后的數(shù)據(jù)塊即可。

關(guān)于Incremental增量備份級(jí)別：

Oracle?9i??共有五種級(jí)別?0?1?2?3?4，0級(jí)最高-4級(jí)最低，0級(jí)是1級(jí)的基礎(chǔ)以此類推。

Oracle?10g官方文檔明確指出增量備份只有0和1兩種級(jí)別（太多增量級(jí)別其實(shí)沒有太大的意義），不過(guò)實(shí)際執(zhí)行增量操作時(shí)，仍然能夠指定多個(gè)級(jí)別，最大能夠支持4級(jí)增量備份。

Oracle?11g?增量備份只有0和1兩種級(jí)別。

Level?0級(jí)就是對(duì)數(shù)據(jù)庫(kù)一個(gè)全庫(kù)備份，增量備份必須從0級(jí)開始，也就是說(shuō)必須要有一個(gè)全庫(kù)備份當(dāng)基礎(chǔ)。

如果你是用“backup?full?database”命令做全庫(kù)備份oracle也不認(rèn)為這是level?0的全庫(kù)備份，盡管是一樣的也要單獨(dú)做一次level?0。有了level?0當(dāng)基礎(chǔ)才能有后面的level?1?level?2?level?3?level?4。如果你一上來(lái)比較沖動(dòng)直接發(fā)出level?1備份，oracle會(huì)自動(dòng)在level1前面加一個(gè)level?0，順序是先進(jìn)行l(wèi)evel?0備份再做level?1備份，一共做兩次備份。

關(guān)于Incremental增量備份類型：

（1）差異增量備份：備份上級(jí)及同級(jí)備份以來(lái)所有變化的數(shù)據(jù)塊，差異增量是默認(rèn)增量備份方式

特點(diǎn)：觸發(fā)條件小于等于當(dāng)前級(jí)別<=N?????備份時(shí)間快，恢復(fù)時(shí)間慢

（2）累積增量備份：備份上級(jí)備份以來(lái)所有變化的塊。

特點(diǎn)：小于當(dāng)前級(jí)別<N???????備份時(shí)間慢，恢復(fù)時(shí)間快????C：代表累積

我們系統(tǒng)的備份策略（周策略），僅供參考，如有雷同心心相印，歐巴~阿加西
日期???????????????差異增量??????????累積增量
星期天?????????????????0??????????????????????0
星期一?????????????????2??????????????????????2
星期二?????????????????2??????????????????????2
星期三?????????????????1??????????????????????1
星期四?????????????????2??????????????????????2
星期五?????????????????2??????????????????????2
星期六?????????????????2??????????????????????2
星期日?????????????????0??????????????????????0

下面我們實(shí)驗(yàn)差異增量備份與累積增量備份~備份時(shí)間與恢復(fù)窗口優(yōu)略性

差異增量備份

記住當(dāng)前的scn號(hào)（10000），我們刪除表test1和表test2，然后恢復(fù)到scn=10000那一刻，檢查表test1和表test2是否完整恢復(fù)回來(lái)，恢復(fù)窗口：恢復(fù)三個(gè)備份集?0+1+1+redo

記住當(dāng)前的sequence號(hào)，我們刪除表test3和表test4，然后恢復(fù)到sequence那一刻，檢查表test3和表test4是否完整恢復(fù)回來(lái)，恢復(fù)窗口：恢復(fù)兩個(gè)備份集?0+1(最后一次備份)+redo

下面我們就做的快一點(diǎn)啦

大家肯定會(huì)發(fā)現(xiàn)一個(gè)有趣的現(xiàn)象，我們備份集順序DB_0to99v4v_1_1->DB_0vo99vgi_1_1->DB_11o99vpa_1_1

-rw-r-----?1?oracle?asmadmin?1023426560?May?10?16:27?DB_0to99v4v_1_1

-rw-r-----?1?oracle?asmadmin??10493952?May?10?16:34?DB_0vo99vgi_1_1

-rw-r-----?1?oracle?asmadmin??20193280?May?10?16:38?DB_11o99vpa_1_1

而我們恢復(fù)順序DB_0to99v4v_1_1->DB_11o99vpa_1_1，沒有中間的DB_0vo99vgi_1_1，這就是累積增量備份的特色，當(dāng)進(jìn)行備份時(shí)它要去找比它自己級(jí)別小的基準(zhǔn)點(diǎn)進(jìn)行增量備份，因此DB_11o99vpa_1_1是從0級(jí)一直備到最新狀態(tài)（包括DB_0vo99vgi_1_1）又根據(jù)Oracle優(yōu)先使用備份集恢復(fù)，用完所有備份集后，在應(yīng)用歸檔日志恢復(fù)，因?yàn)閭浞菁时葰w檔快很多，這一原則，我們可以直接使用DB_11o99vpa_1_1備份集進(jìn)行恢復(fù)了。

小結(jié)：情深深雨蒙蒙~風(fēng)吹草低見牛羊，示例說(shuō)明兩種增量備份的差別實(shí)驗(yàn)已經(jīng)完成，大家從這些實(shí)驗(yàn)中學(xué)習(xí)到東西了嘛！應(yīng)該說(shuō)這兩種增量各有千秋，適合不同的應(yīng)用場(chǎng)景，如何更好的使用它們，要根據(jù)你項(xiàng)目能夠接受的備份及恢復(fù)程度而定，好了我們明天見goodbye?親。

3.演示用catalog數(shù)據(jù)庫(kù)作為RMAN的資料庫(kù)對(duì)數(shù)據(jù)庫(kù)進(jìn)行一次全備份

上面我們說(shuō)過(guò)RMAN元數(shù)據(jù)可以放在控制文件中，其實(shí)還可以放在catalog數(shù)據(jù)庫(kù)中，catalog庫(kù)是個(gè)什么東東呢？我們簡(jiǎn)單的闡述一下它個(gè)功能。

1.??catalog庫(kù)統(tǒng)一管理RMAN備份信息即元數(shù)據(jù)信息，如果沒有catalog庫(kù)，就把RMAN備份信息寫入控制文件

2.??目標(biāo)數(shù)據(jù)庫(kù)必須注冊(cè)到catalog庫(kù)中才能使用

3.??控制文件恢復(fù)成本越來(lái)越低，降低了catalog庫(kù)使用。

4.??控制文件不能保留超過(guò)一年以上的備份信息，catalog可卻可以。

5.??catalog庫(kù)可以同時(shí)保存n臺(tái)數(shù)據(jù)庫(kù)的備份信息，降低管理成本，提升管理效率
