  1. Figure 10-9: Business Continuity Planning • Business Continuity Planning • A business continuity plan specifies how a company plans to restore core business operations when disasters occur

  2. Figure 10-9: Business Continuity Planning • Business Process and Analysis • Identification of business processes and their interrelationships • Prioritizations of business processes • Downtime tolerance (in the extreme, mean time to belly-up) • Resource needs (must be shifted during crises)

  3. Figure 10-9: Business Continuity Planning • Communicating, Testing, and Updating the Plan • Testing (usually through walkthroughs) needed to find weaknesses • Updated frequently because business conditions change and businesses reorganize constantly • Telephone numbers and contact numbers must be updated even more frequently than the plan as a whole

  4. Figure 10-10: Disaster Recovery • Business Continuity Planning • A business continuity plan specifies how a company plans to restore core business operations when disasters occur • Disaster Recovery • Disaster recovery looks specifically at the technical aspects of how a company can get back into operation using backup facilities

  5. Figure 10-10: Disaster Recovery • Types of Backup Facilities • Hot sites • Ready to run (power, HVAC, computers): Just add data • Considerations: Rapid readiness versus high cost

  6. Figure 10-10: Disaster Recovery • Types of Backup Facilities • Cold sites • Building facilities, power, HVAC, communication to outside world only • No computer equipment • Might require too long to get operating

  7. Figure 10-10: Disaster Recovery • Types of Backup Facilities • Site sharing • Site sharing with a firm’s sites (problem of equipment compatibility and data synchronization) • Site sharing across firms (potential problem of prioritization, sensitive actions)

  8. Figure 10-10: Disaster Recovery • Types of Backup Facilities • Hosting • Hosting company runs production server at its site • Will continue production server operation if user firm’s site fails • If hosting site goes down, there have to be contingencies

  9. Figure 10-10: Disaster Recovery • Restoration of Data and Programs • Restoration from backup tapes: Need backup tapes at the remote recovery site • Real-time journaling (copying each transaction in real time) • Database replication

  10. Figure 10-10: Disaster Recovery • Testing the Disaster Recovery Plan • The importance of testing: Find problems, work faster • Walkthroughs • Go through steps in real time as group but do not take technical actions • Fairly realistic • Unable to catch subtle problems
