Hi Todd,
Thanks for your response, I'm actually using DSSv6. Is development in the same position for that product?
I'm sure with last weeks release to manufacturing of Microsoft DPM 2010, which allows for backups of virtual machines running on a CSV but requires hardware to have a VSS provider, this will soon become a highly requested feature for people who are running server 2008R2 clusters.
Many thanks,
Jonathon
