The second location should be used in case of emergency. So, if my first
machine/system becomes unreachable for whatever reason, I want to be
able to switch very quickly to the other machine. Of course, the goal is
to have no loss of data. That is the context.
Furthermore, I have experience with DRBD (not on databases) and I do not
know if DRBD would be the best way to solve this replication problem.
Thanks for any suggestions and explanations.
