title: Configuring specific backup nodes for a Hazelcast Distributed Map?
body: <p>Imagine that an organization has two data centers (named 'A' and 'B' for simplicity) with multiple nodes running in each, and there is a Hazelcast cluster over all of these nodes. Assume that there is a Distributed Map in this cluster, which is configured to have backup-count of 1.</p>
  
  <p>Is there a way to configure the Hazelcast Distributed Map so that nodes in Data Center A are backed up on the nodes in Data Center B and vice versa? This would mean that the event of losing a single data center the Map data (and backup) is not lost?</p>
