snapshotting disk images with exchange db / volumes

[Marc Roos]

Anyone knows how the agent is using the vss service? Where this process 
is documented?

I have been asking at technet about if I could snapshot an exchange db 
volume[1]. But it looks like that windows server backup is sort of doing 
the same. Creating vs image, and backup that one. However they truncated 
the exchange db log files after a succesful procedure. 

I was wondering if someone is doing this already. How does the guest 
freeze work exactly in windows (In linux it is quite clear no io is 
done). I assume that if the guest is invoking the vss service, and then 
you snapshot on the host environment. You have a snapshot with a vss 
image? So if you want to recover, you first need to 'roll back' to that 
internal vss image on the snapshot?
