Re-explain
RTO (Recovery Time Objective) and RPO (Recovery Point Objective) are critical disaster recovery metrics:
- RTO: Maximum acceptable time to restore service after a failure. This is about how fast you can recover.
- RPO: Maximum acceptable amount of data loss measured in time. This is about how much data you can afford to lose.
Example:
If a database fails at 2:00 PM:
- RTO of 1 hour means service must be restored by 3:00 PM
- RPO of 15 minutes means you can only lose data from 1:45 PM onward
These metrics drive backup frequency, infrastructure investment, and recovery strategy decisions.
