NetWorker Module for Microsoft Hyper-V 独立虚拟机还原失败

 在独立 Hyper-V 设置中：

将虚拟机从一个 Hyper-V 服务器还原到另一个 hyper-V 服务器失败，并显示以下错误：

在 NetWorker Module for Microsoft 用户界面监视选项卡中，它显示从恢复中选择的设置;

为同一磁盘添加虚拟机磁盘两次。

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>

仅当从增量备份进行独立 Hyper-V 虚拟机还原时才会发生这种情况：

从完整备份还原独立 Hyper-V 虚拟机工作正常。

还原 Hyper-V 群集虚拟机工作正常。

 在独立 Hyper-V 设置中：

对于完整备份，它对每个磁盘仅显示一个 vhdx 条目，并且从一个 hyper-V 服务器还原到另一个 hyper-V 服务器可以正常工作。

对于增量备份，会看到每个磁盘的重复 vhdxs 条目，并且从一个 Hyper-V 服务器还原到另一个 Hyper-V 服务器将失败。 

使用以下命令检查客户端索引：

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

增量备份的输出显示重复条目：
