Disaster Recovery Engineering: Designing Resilient IT Systems

In an era where even a few minutes of downtime can cost organizations thousands of dollars, building resilient systems is a critical business requirement. Whether facing cyberattacks, hardware failures, or natural disasters, modern IT professionals must know how to keep operations running smoothly. This text-based course guides you through the core principles of disaster recovery engineering, giving you the knowledge to design and implement robust Business Continuity and Disaster Recovery (BCDR) strategies. You will transition from understanding basic backup concepts to structuring resilient cloud-native architectures that withstand major disruptions. What you'll learn: Understand foundational BCDR terminology, including Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO); Design multi-region cloud recovery strategies using modern redundancy and replication patterns; Assess business impact and perform risk analysis to identify critical system vulnerabilities; Integrate modern SRE practices like Service Level Objectives (SLOs) and observability into your recovery plans; Formulate comprehensive incident response and testing protocols to validate recovery readiness. The course starts with essential terminology and the foundational pillars of business continuity before moving into practical cloud-based architectures, backup methodologies, and compliance standards. Through written explanations and realistic scenarios, you will learn how to draft, test, and maintain an actionable recovery playbook. This course is designed for aspiring systems administrators, DevOps engineers, IT managers, and beginners who want to build a solid foundation in system resilience with no prior disaster recovery experience required.
