NetWorker：被动节点中的群集灾难恢复备份失败

灾难恢复存储集的文件系统备份失败，但适用于双节点群集中的本地驱动器。

环境：
安装了 NetWorker 19.x 客户端软件包的 Windows Server 2019 客户端

群集Cluster_Name存储集详细信息>共享驱动器 Q： 和 CSV （C：\ClusterStorage\Volume1）。
>

ClusterNode-1
存储集详细信息 > C：\ 和 DR

群集节点-2
存储集详细信息 > 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.

这意味着某些应用程序安装在 CSV 上，因此它将 CSV 视为关键驱动器。

save -o VSS：LCV=yes 不应将 CSV 列为物理节点上的关键卷。如果 CSV 列为严重，则 DR 备份将失败。在下面的输出（检查“注释”部分）中，可以看到 CSV 在一个节点上列为关键，而在另一个节点上则不是。

从 CSV 中删除已安装的应用程序。

输出来自群集中的一个节点。这会将 CSV 显示为关键卷，因此备份适用于 C：\，而对于来自此节点的灾难恢复存储集则失败。

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.
