Business Impact Analysis - 5.2
Summary
Business Impact Analysis (BIA) assesses key metrics like Recovery Time Objective (RTO), Recovery Point Objective (RPO), Mean Time to Repair (MTTR), and Mean Time Between Failures (MTBF) to determine the impact of system failures and guide recovery strategies.
Notes:
Recovery Time Objective - RTO
- The maximum allowable downtime for a system or application after a failure before significant impact occurs on business operations.
Recovery Point Objective - RPO
- The maximum allowable data loss measured in time, defining the point to which data must be restored to resume normal operations (e.g., last backup).
Mean Time to Repair - MTTR
- The average time it takes to repair a system or component after a failure and restore full functionality.
Mean Time Between Failures - MTBF
- The average time between one system failure and the next, calculated by dividing total uptime by the number of failures.
