What Is DynamoDB Point in Time Recovery (PITR)

Описание: Are you preparing for an AWS certification or architecting a solid database strategy? You absolutely need to master DynamoDB’s backup capabilities. ☁️🛡️

In this deep dive, we break down one of the most critical features you’ll encounter: Point-in-Time Recovery (PITR). Think of it as a time machine for your data! We’ll explain how PITR protects you from accidental writes and deletes with second-by-second granularity.

But PITR isn't a silver bullet. We also explore the crucial differences between RPO (Recovery Point Objective) and RTO (Recovery Time Objective), discussing the "gotchas" that often trip people up on exams—specifically what happens when you actually restore a table. Finally, we compare PITR against On-Demand Backups to help you decide which tool is right for long-term compliance versus disaster recovery.

By the end of this video, you’ll know exactly how to answer the question: "How will we protect this data from disappearing?"

In this video, you will learn: ✅ The difference between RPO and RTO metrics. ✅ How PITR acts as a continuous "safety net" for the last 35 days. ✅ The major operational "gotcha" regarding table settings during a restore. ✅ When to use On-Demand Backups for long-term archival. ✅ Real-world architecture scenarios: Which backup strategy fits your app?
