Once the snapshot exists, it is there, self-consistent and unchanging, 
it can be read at leisure to copy off to a backup.  The volume doesn't 
need to be unmounted or anything.

What mechanisms do other systems have to make this easier?  Some 
internals-to-internals data transport that is more efficient, 
opportunistic, etc., than a file interface?
