In the era of digital transformation, cloud computing has revolutionized how organizations approach resilience and disaster recovery (DR). Traditional recovery methods are increasingly being replaced by cloud-native strategies that offer scalability, cost-effectiveness, and real-time recovery. This paper explores the evolution of disaster recovery in the context of cloud computing, highlights emerging trends, and evaluates various methodologies adopted by enterprises to ensure business continuity. Using a comparative framework, the study analyzes cloud-based DR models, such as Backup-as-a-Service (BaaS) and Disaster Recovery-as-a-Service (DRaaS), and their impact on system resilience. A mixed-method approach, including qualitative analysis and a case study, underpins the findings. The results demonstrate that cloud-native DR solutions significantly enhance operational resilience, reduce downtime, and offer adaptive recovery frameworks. Finally, the paper proposes a resilience architecture model suitable for hybrid and multi-cloud environments.
