I am having this issue as well with a newly installed WHS 2011 server and my Windows 7 Enterprise machine.
I only want to backup my C: to start with which is a 120GB SSD.
I get the same error and only get:
C:\Windows\system32>vssadmin list providers
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2005 Microsoft Corp.
Provider name: 'Microsoft Software Shadow Copy provider 1.0'
Provider type: System
Provider Id: {b5946137-7b9f-4925-af80-51abd60b20d5}
Version: 1.0.0.7
My event log says:
Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process.
Operation:
Gathering Writer Data
Context:
Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220}
Writer Name: System Writer
Writer Instance ID: {4b76855f-fc55-477d-bd90-30882b4a96e5}
And then it times out and repeats the same error until it fails.
Also, here is a link to my error:
http://technet.microsoft.com/en-us/library/cc734235(v=ws.10).aspx
It says to use the command: vssadmin list writers and determine which has the error. However that command reports NO errors. In that case the technet article says:
"If
the command reports that all writers are operating without errors, this means that the error condition is not writer-related. In this case, you should contact the backup software vendor that created the VSS requester application."
:D
That
would be Microsoft I believe lol.
Other programs of note on my computer which may be storage related:
=Microsoft Security Essentials (no other antivirus ever installed)
=SkyDrive App
=Google Drive App / Google Music Sync
=Virtual Clone Drive
Also, not sure if its relevant but I have 7 hard drives currently attached, two of them USB.
I can go through detaching all my drives one by one and uninstalling all of those apps... before that, was wondering if anyone had any ideas. Again, I only want to backup C for now.
