VMware 5, VDR 2.

1 VM is unable to be backed up because of error:

Failed to create snapshot for DC, error -3960 ( cannot quiesce virtual machine)

This was the only machine being backed up at the time and the host is otherwise under no load, so I dont think this is an I/O problem. Destination is a NAS drive (NFS) on a 1GB link LAN,

Had a search about, and I think it is to do with VSS on the Guest OS.

As per this article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1018194

Eventvwr on the OS has a single error 11: The driver detected a controller error on \Device\Harddisk2\DR2.

And cmd > vssadmin list writers gives lots of errors:

C:\Users\administrator.EVO>vssadmin list writers
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2005 Microsoft Corp.

Waiting for responses.
These may be delayed if a shadow copy is being prepared.
