NetWorker：被動節點中的叢集災難回復備份失敗

災難回復儲存集的檔案系統備份失敗，但適用於雙節點叢集中的本機磁碟機。

環境：
已安裝 NetWorker 19.x 用戶端套件的 Windows Server 2019

叢集 > Cluster_Name
儲存集詳細資訊 > 共用磁碟機 Q： 和 CSV （C：\ClusterStorage\Volume1）。

叢集節點-1
儲存集詳細資料 > C：\ 和 DR

叢集節點-2
儲存集詳細資料 > C：\ 和 DR

Error:

99128:save:Disaster Recovery: critical volume C:\ClusterStorage\Volume1\ identified for disaster recovery backup has been created on a CSV volume. Backup of critical volume on CSV volume is not supported.

這表示某些應用程式安裝在 CSV 上，因此會將 CSV 視為關鍵磁碟機。

save -o VSS：LCV=yes 不應將 CSV 列為實體節點上的關鍵磁碟區。如果 CSV 列為嚴重，則 DR 備份會失敗。在以下輸出結果 （檢查備註區段） 中，可以看到 CSV 在一個節點上列為嚴重，而在另一個節點上則不是。

從 CSV 中移除已安裝的應用程式。

輸出來自叢集中的其中一個節點。這會顯示 CSV 為嚴重磁碟區，因此備份可針對 C：\ 運作，而從此節點備份 DR 儲存集則會失敗。

The following volumes are determined as critical by the system state writers:
C:\ (disk num 0)
The following volumes are critical because they are parents for one or more mounted critical volumes:
The following volumes are critical because they are in the same dynamic disk pack with one or more critical volumes:
The output is from another node from Cluster which doesn't show CSV as critical volume and hence backup works for both C:\ and DR saveset.
