I've run that. Every once in a while, I still see VSS errors. Sometimes I 
just turn VSS off, for certain clients ...

Not unless you are specifically seeing the errors mentioned in your event 
logs, I would think. I have a similar config (clustered Win2003 servers, 
as storage nodes, with SAN disk space as AFTD devices), mostly for SQL, 
altho my largest is a file server (1.5TB).

Now, there's a good question ...
