Disaster Recovery, Backups, and Snapshot Management
Disaster Recovery, Backups, and Snapshot Management in the context of Retrieval-Augmented Generation (RAG) refer to strategies and tools used to ensure data integrity and availability for AI systems. Disaster recovery prepares for unexpected failures, backups create secure copies of critical data, and snapshot management captures specific system states. Together, they enable rapid restoration and continuity of RAG models and their knowledge bases, minimizing downtime and data loss during disruptions.

💡 Key Takeaways
- Distinguish disaster recovery, backups, and snapshot management and know their roles in data protection.
- Compare backup types (full, incremental, differential) and when to use each.
- Use snapshots for quick, point-in-time recovery and safe testing without impacting production.
- Define RPO and RTO and align backup and DR plans to meet them.
❓ Frequently Asked Questions
What is disaster recovery and why is it essential?
Disaster recovery (DR) is the process of restoring IT services after a disruption. It defines goals like RTO (recovery time objective) and RPO (recovery point objective) to minimize downtime and data loss.
What is the difference between backups and snapshots?
Backups are copies of data kept for long-term restoration, often with multiple versions. Snapshots capture a point-in-time state of a volume or system, enabling fast rollbacks but relying on the storage system and not always standalone backups.
What is the 3-2-1 backup rule?
Keep 3 copies of data on 2 different media with 1 copy kept off-site to protect against failures, disasters, and corruption.
What are RPO and RTO?
RPO (recovery point objective) is the maximum acceptable data loss; RTO (recovery time objective) is the maximum acceptable downtime. They guide how aggressively you back up and replicate data.
How should you test disaster recovery and perform restores?
Regularly run drills, verify data integrity, validate that restores meet RTO/RPO targets, document findings, and update the DR plan based on lessons learned.
