Designing Cloud Disaster Recovery: Calculating RTO and RPO for High Availability

# Architecting Cloud Disaster Recovery Plans Every modern enterprise must operate with a documented Disaster Recovery (DR) plan. The core foundation of any DR strategy rests upon two mission-critical metrics: **RTO (Recovery Time Objective)** and **RPO (Recovery Point Objective)**. ## Defining the Core Metrics - **Recovery Point Objective (RPO)**: The maximum acceptable age of files or data that must be recovered from backup storage for normal operations to resume if a failure occurs. - **Recovery Time Objective (RTO)**: The maximum acceptable duration of time that can elapse before infrastructure and applications must be fully restored following a disruption. ## Swift2Cloud Multi-Region Failover Architecture By leveraging automated block-level snapshots paired with cross-region replication, Swift2Cloud enables enterprises to achieve near-zero RPO with sub-15 minute automated failover.
