I have a web app with 2 web servers and 2 database servers. The dbs are setup for multi master replication. (this is the primary environment)
I also have the exact same setup on a different location acting as standby, in case the primary env fails. (this is the backup env)
What I need is for the backup env to be in sync with the dbs of the primary site. However, all dbs in both environments have already replication configured.
How can I achieve my goal?
Thanks
