Overview
Disaster Recovery Planning (DRP) is a subset of business continuity planning that focuses on the technical aspects of recovering IT systems, data, and networks after a disaster (e.g., fire, flood, or massive cyberattack).
Key Metrics
- Recovery Time Objective (RTO): The maximum acceptable length of time that a computer, system, network, or application can be down after a failure or disaster.
- Recovery Point Objective (RPO): The maximum acceptable amount of data loss measured in time.
Common Strategies
- Backups: Regular copies of data stored off-site or in the cloud.
- Cold Site: A backup facility with little or no hardware installed.
- Hot Site: A fully functional backup facility with real-time data replication.
