Difficulty: Easy
Correct Answer: Incorrect
Explanation:
Introduction / Context:
Disaster recovery (DR) addresses region-level risks: fires, floods, ransomware, data center failures. If your backups are stored only on-site, the same disaster that destroys production can destroy your ability to recover. Therefore, off-site backup shipment or replication is a foundational DR requirement.
Given Data / Assumptions:
Concept / Approach:
A sound DR plan uses one or more of: off-site vaulting of encrypted media, cross-region object storage, log shipping, snapshot replication, or fully managed cross-region database replicas. Periodic test restores validate that backups are usable. Chain-of-custody and key management ensure confidentiality and integrity while in transit and at rest.
Step-by-Step Solution:
Define RTO/RPO and choose off-site replication or shipment accordingly.Encrypt backups; separate encryption keys from backup storage.Automate transfer to secondary locations; monitor success and latency.Perform scheduled DR drills with full restore procedures.Continuously improve based on drill outcomes and incident learnings.
Verification / Alternative check:
Run a failover simulation assuming the primary site is unavailable. If you can restore from the off-site copy to meet RTO/RPO, the plan is adequate; if not, the gap reveals missing off-site provisioning.
Why Other Options Are Wrong:
Correct (as an answer to the original false claim) would wrongly suggest off-site is unnecessary.Only for cloud or archives: on-premises and hot transactional systems equally require off-site protection.
Common Pitfalls:
Keeping backups in the same blast radius, untested restores, weak key management, and forgetting to protect the backup catalog itself.
