Nice question, and able to finish lunch,
however . . .
I would have asked Junior why he didn't BACKUP the database for this purpose. BOL - "Reverting is not intended for media recovery. . A database snapshot is an incomplete copy of the database files, so if either the database or the database snapshot is corrupted, reverting from a snapshot is likely to be impossible. Furthermore, even when it is possible, reverting in the event of corruption is unlikely to correct the problem. Therefore, taking regular backups and testing your restore plan are essential to protect a database." Snapshots primary purpose are for reporting needs.
