[Zope] - backing up Data.bbb

[Roman Milner]

    Following a corrupted Data.bbb disaster I want to automate the
backing up of my Data.bbb.  My question is - do I need to shut down
zope before copying Data.bbb to ensure that it is closed properly?
    If so, how can I shutdown zope properly from the command line?

    Thanks,
