NetWorker 配置为执行 Azure 虚拟机快照保护。
Azure 虚拟机快照还原立即失败,并在 nsrazure_recover 日志:

Cause
即使拥有正确的权限,仍可能会发生此授权失败的情况。当 Azure 存储帐户缺少配置的专用终结点连接时,就会发生这种情况。

提醒:Azure 存储帐户专用终结点连接用于通过 Microsoft 网络(而不是公共 Internet)将虚拟网络 (VNET) 中的资源安全地连接到 Azure 存储帐户。在还原 Azure VM 的上下文中,这在还原过程中增强安全性和确保专用连接方面起着至关重要的作用。
Resolution
有两个选项:
- 如果必须使用指定的存储帐户,则 Azure 管理员必须为 Azure 存储帐户配置专用终结点连接。
- NetWorker 备份管理员可以在恢复期间指定不同的 Azure 存储帐户。存储帐户必须与目标磁盘位于同一目标 Azure 区域中,并且必须配置专用终结点连接。
Additional Information
如果在还原期间指定的存储帐户与目标磁盘位于不同的 Azure 区域,则还原将失败:NetWorker:Azure VM 快照还原失败,“源 blob 与磁盘不属于同一区域”
