How can you sync 2 database to be identical in the case of a failover,
where one server goes down, the other already has all of the correct
info, then if the primary comes live, the secondary sync's all of it
data back?

With a lot of work.  Or by paying $$$$ to a contractor.

Or by waiting to Jan Wieck's new replication engine, expected in 6 months or
so.

What's your deadline & params?
