MySQL on Docker: Multiple Delayed Replication Slaves for Disaster Recovery with Low RTO

A delayed replication slave is useful in recovering from accidental data deletion. But how long should the delay be? Too short delay might not be enough for you to get to a terminal and stop an offending query. Too long delay means a long recovery time when catching up.

This blog post shows how to deploy multiple MySQL delayed slaves on one single physical host with Docker, and shows some of the recovery scenarios.

Database Backups - Comparing MariaDB Mariabackup and Percona Xtrabackup
