That message seems to indicate that you are restoring using the
REPLACE_DATABASE option. I refer to this as the DESTROY_DATABASE
option. So your application is busy destroying the database while you are
connected to it. Don't do this!! In Firebrd 2 you won't be able to
without an explicit (different) command parameter; but in 1.5 you can and
you shouldn't.

So my recommendations for both questions is "Don't". Backing up from an
end-user application is OK; but restoring should be done by a separate,
restricted application and it should restore using the CREATE_DATABASE
option, making an intermediate, off-line version. Someone should test that
the off-line version works. If it does, then take the "live" database
right off-line, rename it and then rename the fresh database to the "live"
name.
