How do I enable Multi-AZ replication and automatic failover for my Redis cluster?

I want to improve fault tolerance for my ElastiCache cluster running Redis. How do I enable Multi-AZ replication and automatic failover?

Follow the instructions at Minimizing Down Time: Multi-AZ with Automatic Failover. You can enable Multi-AZ replication with automatic failover when you create a new Redis cluster, or for existing clusters with an existing replication group.

Note: When implementing a replication solution, be sure that you’ve allocated enough memory to create a point-in-time Redis snapshot.
