Building a database disaster recovery plan requires careful consideration of several factors, including high availability (HA) and disaster recovery (DR). HA focuses on minimizing downtime and ensuring continuous operation, while DR aims to restore the database and its associated services after a catastrophic event. Defining Recovery Point Objectives (RPOs) and Recovery Time Objectives (RTOs) is crucial in setting goals for data loss and system recovery time. Databases are stateful, meaning they rely on previous actions, which makes disaster recovery more complex than fixing application issues. MySQL replication allows data to replicate across multiple servers, reducing downtime and enabling faster recovery. A robust backup strategy is essential, with logical and physical backups used to recreate the database from scratch or copy files stored on disk. Automating the recovery process can minimize human error and ensure consistency, while regular testing helps validate the plan's effectiveness and identify areas for improvement.
