Azure Service bus premium tier doesn't allow message replication in case of geo-disaster. Availability zones provide replication across data centers within a region but are not enabled for all regions right now. In the event of disaster no replication is provided across regions, how service bus ensures messages are not lost or Is it to be managed by the developer?

Standard tier says about active-active active-passive. But in our scenario we need premium subscription and paired regions solution seems incomplete since messages are not replicated.
