Hi,
Based on my opinion and setups.
I would keep etcd cluster on separate nodes and separate data centre.
Mumbai down means whole pg patroni cluster is down, because you dont have
an etcd quorum. And other reasons, why create separet etcd cluster.
Take a backup from leader. Leader donw means no replicas. Replica down does
not mean leader down.
