How do I minimize data loss during scheduled maintenance of my ElastiCache nodes running Memcached?

Last updated: 2020-09-24

One or more of my Amazon ElastiCache nodes running Memcached is scheduled for maintenance. Because Memcached doesn’t offer a replication or failover option, how do I minimize the loss of data that can occur when my nodes are replaced?


You can find a list of potential options at Replacing nodes.
