Thanks Riaan and sorry for the late response.. i was away.
I red that paragraph too in the admin guide and we are all good. I have just installed the Symantec VSS providers and ASC seems to have worked on backend SQL vm but still failing on front end web vm with error 13..

file read failed(13)
there appears to be snapshot error.. i have checked the bpfis logs and shows the following.. its definitely not a permission issue as subsequent job where it backs up the whole vm after taking the snapshot finishes okay. any idea?
