適用於 Microsoft Hyper-V 獨立虛擬機器還原失敗的 NetWorker 模組

 在獨立 Hyper-V 設定中：

將虛擬機器從一台 hyper-V 伺服器還原至另一台伺服器失敗，並出現下列錯誤：

在使用者介面監控Microsoft NetWorker 模組標籤中，會顯示從還原中選取的設定;

相同磁碟的虛擬機磁碟會新增兩次。

Hyper-V virtual machine recovery options:
          Source Hyper-V Server:<Source Hyper-V Server name>
          Destination Hyper-V Server: <Destination Hyper-V Server name>
          Destination path for the Hyper-V virtual machine configuration files: <Recovery directory>
          Destination path for the virtual machine:
               VM_NAME, G:\VM_NAME\VM_NAME-VHHDX_ID-DISKNAME.vhdx = < Recovery Directory>
                VM_NAME, G:\VM_NAME\VM_NAME-VHHDX_ID-DISKNAME.vhdx = < Recovery Directory>
          Host, on which the recovery process is run: <Destination Hyper-V Server name>

只有從增量備份進行獨立 Hyper-V 虛擬機器還原時，才會發生這種情況：

從完整備份還原獨立 Hyper-V 虛擬機器運作正常。

還原 Hyper-V 叢集虛擬機器運作正常。

 在獨立 Hyper-V 設定中：

對於完整備份，它僅顯示每個磁碟的一個 vhdx 條目，並且從一個 Hyper-V 伺服器還原到另一個伺服器工作正常。

對於增量備份，會看到每個磁碟的重複 vhdx 條目，並且從一個 hyper-V 伺服器還原到另一個伺服器失敗。 

使用下列命令檢查用戶端索引：

nsrinfo -vvv -n all <Hyper-v Server Name> > c:\nsrinfo.txt

增量備份的輸出顯示重複項目：
