My snapshots are restored in a crashed state. Basically as if the power was cut on the server. There is no client state remembered after the machine boots back up. With this set-up I can restore a production machine in a matter of minutes without any downtime for the back-up and without any of the issues you mentioned. I only back-up snapshots once a month (just to prevent rebuilding from scratch) and then do a file level restore from the back-ups.
