I think you mean vssadmin and not diskpart

e.g.: vssadmin list writers

When I try this, I get the following error:

"The component "Microsoft Hyper-V VSS Writer" was not found in the writer components list. Aborting backup ...

Check the syntax of the component name."

I have been able to get it to work, but the VSS Hyper-V writer isn't listed.

The backup seems to be going okay, I have yet to try restoring it to a different hyper-v server to bes ure.

Do you have any more information about whether or not the VSS writer you mentioned must be included?

Or is it possbile that in Hyper-V RTM, the seperate Hyper-V writer has been integrated into some system driver?

I have also used VSSAdmin to list the writers, which give a much more compact overview, but it's not listed there either.

Any help would be greatly appreciated.

hi there,

you need to ensure that you are running the backup as an administrator and that the Hyper-V role has been enabled on Win2k8. Then the VSS writer for Hyper-V should show up.

I got the same error as KarlMitschke above. When I removed the Writer Verify line, a Shadow Copy was created. However, when I restored a Virtual Machine from the Shadow Copy and started it, an error message was reported that it was shutdown unexpectedly. That's what was fixed by VShadow.exe in Server 2003, and which the new Diskshadow utility with the Hyper-V VSS Writer is supposed to prevent. And yes, Hyper-V is installed and running, and I am logged on as an admin. Any ideas anyone?
