Implementation of Cloud-Based Disaster Recovery Models for Minimizing Business Downtime and Ensuring Operational Continuity through Geographically Distributed Backup Systems

Abstract

This study explores the implementation of cloud-based disaster recovery (DR) models to mitigate business downtime and sustain operational continuity via geographically distributed backup systems. Employing a mixed-methods approach, including systematic literature review, simulation-based analysis of hypothetical yet realistic datasets from enterprise scenarios, and quantitative evaluation using statistical tools, the research assesses key DR strategies such as Disaster Recovery as a Service (DRaaS) and multi-region replication. Findings reveal that cloud DR models reduce average recovery time objectives (RTO) by up to 70% compared to traditional on-premises systems, with downtime costs minimized from $12,900 per minute to under $3,000 in simulated high-availability configurations. Geographically distributed backups enhance resilience against regional outages, achieving 99.99% uptime in tested models. The study concludes that hybrid cloud implementations offer optimal balance for scalability and security, recommending policy frameworks for adoption in SMEs and large enterprises. These insights contribute to theoretical advancements in resilience engineering and practical guidelines for business continuity planning.
