Resiliency and DR

A framework for designing disaster recovery architecture around recovery tiers, not vendor features -- covering RPO/RTO definitions, tier models, and the organizational decisions that determine whether DR actually works.

A practical breakdown of what to back up in a Kubernetes cluster, what's recoverable without backups, and how to build automated backup pipelines with CronJobs and external storage.

War stories and patterns from real disaster recovery failures -- what went wrong, why the plan didn't hold up, and what the recovery actually looked like.
