That moment was the dragon I needed to slay: unreliable backups and a disaster‑recovery plan that lived only on paper.
The reality hit hard: a simple dump isn’t enough when you need point‑in‑time recovery, or when your storage layer fails. If you’ve ever felt that sinking feeling when a DELETE statement runs without a WHERE clause, you know exactly what I mean.

Backups aren’t just about copying files; they’re about capturing a continuous stream of changes so you can rewind to any moment, like rewinding a movie to the exact frame you need. For PostgreSQL (the principles apply to most SQL databases), that means combining:
