Proving Data Integrity: The "Acid Test" for PostgreSQL

The Problem: Schrödinger's Backup

In 2025, storing a backup on S3 is only 50% of the job. The "Acid Test" is the industry standard for verification: a backup is not valid until it has been successfully restored in an isolated environment.

1. The 2025 Paradigm Shift

In 2025, a "Full-Stack" developer must think like a "Systems Architect." The "Golden Stack"—comprised of Next.js 15 for high-performance SSR and Strapi 5 for headless content management—requires a deployment strategy that prioritizes Environment Parity. If your local development environment doesn't mirror production's High-Availability (HA) constraints, your CI/CD pipeline is a liability.
