backing up stopped node?

[Jan Koum]

hi there,

we use ejabberd which uses both erlang and mnesia.  what is the best way to
backup mnesia database without having the node running?

in other words, we don't want to run 'ejabberdctl backup' on a live and
heavily loaded ejabberd server. so we want to do 'ejabberdctl stop' first --
however, after we stop the node, we obviously can't run 'ejabberdctl backup'
against it.  is there a simple solution/workaround to this?

thanks.
