Problem

Status 156 on Hyper-V Backup - The Hyper-V integration component is missing.

Error Message

Status Code: 156

Solution

Make sure the proper version of the Hyper-V virtual machine integration component is installed on the virtual machine. The integration component should be at version 6.0.6001.18016 or later. It should also be the same version as D:\Windows\System32\vmms.exe on the Hyper-V server. Otherwise, the backup fails with status code 156.

To determine the integrated component version, right-click on the following file on the virtual machine and click Properties > Details:
C:\Windows\System32\vmicsvc.exe

This file is the integration service running in the virtual machine.
 
In order to perform an "online" backup of a hyper-v virtual machine, the "Backup" component of the Hyper-V Integration Tools must be installed on the virtual machine.  Otherwise, Hyper-V will be unable to quiesce and snapshot the VM, and the backup will be considered "offline". 
If "Allow offline backup" is set to No in the policy, then the backup will fail with status 156.
