W10 Azure backup failing on virtual disk service 0x086c6
All I can add is "me too" - Win Pro 1709 Build 16299.19 retail - clean reinstall of the agent 2.0.9088. Error 0x086C6 The backup could not be started because of an unexpected error in the virtual disk service. Seems the disk service starts and runs fine.

I have been working with Azure Developer Support on this and they tell me that it is a known issue and will be resolved in an update for 1709 Build 16299.19
From Azure Support:
Hi Thomas,
I’ve ran a few more tests and was able to reproduce the issue on 3 different computers, without having to do anything additional.
I was also able to have a working backup on a Win10 machine running version 1709, on this particular machine I had the backup already enabled and then upgraded Win10 to 1709. I’m not 100% sure that method will not trigger the issue at all, but worked for me on this test. As you point out below, it is possible to be running that version of Win10 and have it working.
The bug has been confirmed to be an issue with the agent running on Win10 1709 as well as with another version of Windows Server 2016. This is being worked on by the product team at this time.
Thanks,
