Azure VM快照级别备份问题 [英] Azure VM Snapshot level backup issue

问题描述

我们有一个带有2 TB磁盘的Azure虚拟机.

We have an Azure Virtual Machine with 2 TB disks.

在虚拟机中，我们将存储副本作为功能而不是DFSR来将磁盘复制到其他虚拟机.

Within the virtual machine, we are using Storage Replica as a feature instead of DFSR for replicating disks to other virtual machine.

每当我们运行Azure快照级别的备份时，每次都会失败.失败，并显示VSS编写器不稳定的消息.

Whenever we run an Azure Snapshot level backup, it fails every time. It fails with the message that VSS writers are not stable.

我通过重新启动各自的服务使写入器稳定，然后重新运行备份，再次导致备份失败.检查日志后，我发现它可能与存储副本有关.有没有一种方法可以将驱动器从Azure快照级别备份中排除.

I make writers be stable by restarting respective service and then rerun the backup, it fails again. Upon checking the logs, I found that it might have to do with storage replica. Is there a way to exclude a drive from Azure Snapshot level backup. 

任何线索都可以解决此问题.

Any clues what can be done to fix this.
