Subject: Information Technology IT
Lesson Topic: Describe disaster recovery strategies
Learning Objective/s:
  • Describe the purpose and essential components of a disaster recovery (DR) plan.
  • Compare the main DR strategies (backup‑centric, replication, site‑based, cloud‑based) and their typical RTO/RPO trade‑offs.
  • Explain how RTO and RPO determine the choice of backup media and recovery site.
  • Develop a concise DR plan outline that assigns roles, documents procedures, and includes a testing schedule.
Materials Needed:
  • Projector and screen
  • Whiteboard and markers
  • Student handout: DR strategy comparison table
  • Sample backup media (USB drive or external HDD)
  • Diagram of DR workflow (printed or digital)
  • Laptops with internet access for research
  • Worksheet for drafting a mini DR plan
 Introduction:
Begin with a brief news clip about a recent cyber‑attack that shut down a major service. Ask students what steps they think the organization should take to restore operations. Remind them they have already studied backup concepts, and today they will evaluate full disaster recovery strategies. Success will be measured by their ability to explain and compare at least three strategies and propose a basic recovery plan.
Lesson Structure:
  1. Do‑now (5’) – Quick quiz on backup types and RTO/RPO definitions.
  2. Mini‑lecture (15’) – Overview of DR strategies, using the comparison table.
  3. Group activity (20’) – Teams analyse a case scenario and select the most suitable strategy, justifying RTO/RPO fit.
  4. Hands‑on demo (10’) – Demonstrate restoring a file from external drive and from cloud backup.
  5. Plan drafting (15’) – Students fill out the worksheet to outline a DR plan for the scenario, assigning roles and testing frequency.
  6. Gallery walk (10’) – Groups exchange plans, give peer feedback using a checklist.
  7. Exit ticket (5’) – Write one key factor that influences the choice of a DR strategy.
Conclusion:
Summarise how RTO, RPO, budget and criticality shape the selection of a disaster recovery approach. Collect the exit tickets and highlight a few strong justifications. Assign homework: research a real‑world DR failure case and write a brief reflection on what could have been improved.
