Uni-directional disaster recovery

ECH ECK ECE Self-Managed

Learn how to failover and failback between two clusters based on uni-directional cross-cluster replication. You can also visit Bi-directional disaster recovery to set up replicating data streams that automatically failover and failback without human intervention.

• Setting up uni-directional cross-cluster replication replicated from clusterA to clusterB.
• Failover - If clusterA goes offline, clusterB needs to "promote" follower indices to regular indices to allow write operations. All ingestion will need to be redirected to clusterB, this is controlled by the clients (Logstash, Beats, Elastic Agents, etc).
• Failback - When clusterA is back online, it assumes the role of a follower and replicates the leader indices from clusterB.
