Why ? > Getting half-crypted DB copy is something too exotic :-) Physical backup is "physical backup", i.e. page-level copy of a database. It have nothing common with encryption state, and i see no problem if physical backup of half-encrypted database is also half-encrypted. For the paranoid admins we can make option in nbackup to encrypt pages before writting them into backup (of course file system copy will be half-encrypted, but admins are informed and have a choice). I see no reason to disallow backup's while encryption is in progress.
