Day 41: Database Backup and Recovery for AI Quiz Platform
What We’re Building Today
Today we’re implementing a production-grade backup and recovery system that could save your quiz platform when disaster strikes. We’ll build automated backup orchestration, point-in-time recovery, and real-time monitoring - the same patterns Netflix uses to protect billions of viewing records.
Today’s Learning Objectives
Multi-tier backup strategy (hot, warm, cold)
Automated backup scheduling with retention policies
Point-in-time recovery system
Backup validation and integrity checking
Recovery orchestration dashboard
Why This Matters in Production Systems
When Slack lost 4 hours of messages in 2017, they had backups but recovery took 3 days. The issue wasn’t having backups - it was backup orchestration and validation. Today’s lesson teaches you to build systems that recover in minutes, not days.
Your quiz platform stores user progress, AI model responses, and analytics. Lose this data, and users lose trust forever. But naive backup approaches create more problems than they solve.
