I think this question is for the Microsoft support. Looks like WSB could not work correctly. Do you have the latest version of WSB?

I'm going to wait for the issue repeat once again to do some new test. Then, based in the outcomes I'll decide what to do next.

Hello! <br />
I’ve been struggling for a while with the following case:<br />
I’ve have two servers with Windows Server 2016 + Hyper-V role installed. I use WSB to backup VM’s from the Host and everything works fine, except when randomly (every month, every two weeks, etc.) the backup fails. So, I realized when that happen is because the Hyper-V items is not listed in the Select Items Windows. I can see all drive listed including the BMR, System state, EFI System Partition and Recovery Partition. &nbsp;If I use wbadmin.exe, then, I got the error: <br />
<br />
<i>Retrieving volume information...<br />
ERROR - The Hyper-V component 'Server Name' specified is invalid.<br />
The specified component spec is invalid. </i><br />
&nbsp;<br />
Short story, the only way that all came to normally is rebooting the servers but this is not the ideal solution. So, I came here looking for you helps guys.<br />
&nbsp;<br />
Thank you in advance!

Hyper-V items is not listed in the Select Items Windows

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

Windows OS

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

Windows 10

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

Hyper-V

Microsoft Azure is a cloud computing platform and infrastructure for building, deploying and managing applications and services through datacenters. It provides both platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS) services and supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems. Cloud Services is a PaaS environment and can be used to create scalable applications and services; there are specific software development kits (SDKs) provided by Microsoft for Python, Java, Node.js and .NET. Azure also has file and storage services, data management, analytics and DNS services.

Azure

Windows Server 2016 is the successor to Windows Server 2012 R2. Built upon the same core code as Windows 10, Windows Server 2016 brings enhancements in security, servicing, and connectivity. A particular focus on this release was hybrid-cloud scenarios, and has close ties to Azure and other Microsoft cloud initiatives. This does not detract from the many improvements that are available for on-premises-only deployments

Windows Server 2016 comes in Datacenter, Standard, and Essentials editions, and for servicing, has adopted windows 10's cumulative model. The new nano-server install is designed to be remotely managed and is designed to be kept current through continuous feature updates. The full GUI install operates similarly to windows 10's "Long Term Servicing Branch" (LTSB) model with cumulative security updates.

Windows Server 2016 has also shifted from a per-processor-and-CAL licensing model to a per-core-and CAL licensing model. This brings Windows Server's licensing more in line with Microsoft's other products and makes hybrid-cloud license planning easier as well.
