    Study Notes

    Business Continuity and Disaster Recovery Planning

    • Running a business continuity and disaster recovery planning project involves developing business continuity and disaster recovery plans, testing them, training users, and maintaining a planning life cycle.

    What is a Disaster?

    • A disaster is any natural or man-made event that disrupts business operations, requiring a significant and coordinated effort to achieve recovery.

    Types of Disasters

    • Natural disasters include:
      • Geological: earthquakes, volcanoes, lahars, tsunamis, landslides, and sinkholes
      • Meteorological: hurricanes, tornados, wind storms, hail, ice storms, snow storms, rainstorms, and lightning
      • Other: avalanches, fires, floods, meteors and meteorites, and solar storms
      • Health: widespread illnesses, quarantines, and pandemics
    • Man-made disasters include:
      • Labor: strikes, walkouts, and slow-downs that disrupt services and supplies
      • Social-political: war, terrorism, sabotage, vandalism, civil unrest, protests, demonstrations, cyber attacks, and blockades
      • Materials: fires, hazardous materials spills
      • Utilities: power failures, communications outages, water supply shortages, fuel shortages, and radioactive fallout from power plant accidents

    How Disasters Affect Businesses

    • Disasters can cause:
      • Casualties: employee or family member injuries, fatalities, or care for others
      • Direct damage to facilities and equipment
      • Transportation infrastructure damage: delays deliveries, supplies, and employee commutes
      • Communications outages
      • Utilities outages

    How BCP and DRP Support Data Security

    • BCP and DRP support availability, which is one of the three pillars of data security, along with confidentiality and integrity.

    Developing Key Recovery Targets

    • Obtain senior management buy-in on key recovery metrics, such as:
      • MTD (maximum tolerable downtime)
      • RTO (recovery time objective)
      • RPO (recovery point objective)
      • RCO (recovery consistency objective)
      • RCapO (recovery capacity objective)
    • Publish these metrics in a database or spreadsheet listing all business processes.

    Sample Recovery Time Objectives

    • RTOs vary depending on the technology required, such as:
      • 8-14 days: new equipment, data recovery from backup
      • 4-7 days: cold systems, data recovery from backup
      • 2-3 days: warm systems, data recovery from backup
      • 12-24 hours: warm systems, recovery from high-speed backup media
      • 6-12 hours: hot systems, recovery from high-speed backup media
      • 3-6 hours: hot systems, data replication
      • 1-3 hours: clustering, data replication
      • < 1 hour: clustering, near real-time data replication

    Criticality Analysis

    • Rank processes by criticality criteria, such as:
      • MTD
      • RTO
      • RPO
      • RCO
      • RCapO
      • Cost of downtime or other metrics
      • Qualitative criteria: reputation, market share, goodwill

    Business Resumption Planning

    • Business resumption planning involves:
      • Alternate work locations
      • Alternate personnel
      • Communications: emergency, support of business processes
      • Standby assets and equipment
      • Access to procedures, business records

    Restoration and Recovery

    • Restoration and recovery involve:
      • Repairs to facilities and equipment
      • Replacement equipment
      • Restoration of utilities
      • Resumption of business operations in primary business facilities

    Improving System Resilience and Recovery

    • Improving system resilience and recovery involves:
      • Off-site media storage: assurance of data recovery
      • Server clusters: improved availability, geographic clusters
      • Data replication: hardware, OS, DBMS, application, current data on multiple servers even in remote places

    Training Staff

    • Training staff involves:
      • Everyday operations
      • Recovery procedures
      • Emergency procedures
      • Resumption procedures
