To the OP:
It would be helpful if you were more descriptive about what you are
trying to accomplish. Are you worried about disk failures? Are you
worried about the whole system failing? What about the case where
invalid data is added to the database? (or the database gets corrupted
in general?) Do you want to have a hot backup of the database
standing by so you can switch to it if the main one goes down? Each
of these have different solutions.
