I'm still not sure I follow, but there's a technique which isn't
worth much for backup proper, but can be a good way to repeatedly
get to a consistent starting point for tests in some circumstances.
Look at CREATE DATABASE x WITH TEMPLATE y.
You can do that once to capture a starting point for testing. You
can drop the testing database and re-create at will.
If this and the various backup techniques don't do what you want,
I'm at a loss. I think you'd need to post something a bit more
concrete for me to understand what you mean.
