Symptoms

Avamar Hyper-V 备份失败或完成，但有例外情况。特定 Hyper-V 节点中的所有虚拟机都从备份中排除，并显示错误：“Error ：虚拟机“”的检查点创建失败，将从备份中跳过。

备份日志中的相关部分： 
avhypervvss Error : Checkpoint creation for Virtual machine '' has failed and will be skipped from backup. For details, please check 'winclustersvc.log'.
avhypervvss Error : Checkpoint creation for Virtual machine '' has failed and will be skipped from backup. For details, please check 'winclustersvc.log'.

avhypervvss Error : Checkpoint creation for Virtual machine '' has failed and will be skipped from backup. For details, please check 'winclustersvc.log'.
avhypervvss Info : --------------------Start [EMC Avamar Plug-in Service for Windows] log ----------

winclustersvc.log 的相应部分位于“EMC Avamar backup cluster client for ”所有者的 C：\Program Files\avs\var\ 文件夹中。这可从故障转移群集管理器确定。

要显示这些消息，必须在 winclustersvc 中的客户端上启用调试。本文的“其他信息”部分介绍了如何启用调试。 
winclustersvc WARN:  WMI API returned error: 'Failed to create checkpoint on collection 'AvamarBackup_-app-' ().
The operation failed.
Guest cluster validation on VM group 'AvamarBackup_-app-' () failed for checkpoint creation.
Size of the VM group 'AvamarBackup_-app-' () is not same with the size of the guest cluster.'  
winclustersvc DEBUG: : Retry '1', WMI API 'CreateSnapshot' for VMGroup 'AvamarBackup_-app-' 
winclustersvc DEBUG: ===> ValidateOutput  
winclustersvc DEBUG: WMI API return value is: '4096' 
winclustersvc DEBUG: Waiting for Job to complete... 
winclustersvc DEBUG: WMI job completed with status '10'  
winclustersvc WARN:  WMI API returned error: 'Failed to create checkpoint on collection 'AvamarBackup_-app-' ().
The operation failed.
Guest cluster validation on VM group 'AvamarBackup_-app-' () failed for checkpoint creation.

Cause

当从备份数据集中的特定 Hyper-V 节点中选择多个虚拟机时，Microsoft WMI API 会生成这些消息。

Resolution

Hyper-V 节点应安装所有最新的 Microsoft 更新。

所有虚拟机均未配置磁盘集、共享磁盘或来宾 CSV。Hyper-V 映像备份不支持此功能。

解决 方案：
  • 使用较小的组。 
  • 从备份数据集中的特定节点中选择更少的虚拟机。
  • 向 Microsoft 创建案例，以解决 Hyper-V 节点上的 WMI API 问题。  

Additional Information

要在 winclustersvc 中启用调试 ，请执行以下操作：
  1. 使用记事本在 Hyper-V 节点上的 C：\Program Files\avs\var\ 文件夹中创建 winclustersvc.cmd —“EMC Avamar backup cluster client for ”的所有者
  2. 向其添加 --debug 。
  3. 在 Hyper-V 节点上重新启动“EMC Avamar Plug-in Service for Windows”。 
  4. 重新运行备份以重现问题。
