OR if you are able to take a point-in-time snapshot at the volume level,
say using LVM or some SAN management tool. The effect is the same as if
the server is hardware reset unexpectedly, in that it requires recovery
when next started but is otherwise fine.
Of course, you still need all of your database including the logs etc.
