Disaster recovery plan (DRP)
A disaster recovery plan (DRP) documents the procedures to follow to restore IT services after a major incident: server failure, cyberattack, or natural disaster. It defines RTO, RPO, and responsibilities for each team member involved.
In practice
An effective DRP is a short document accessible offline (printed PDF or encrypted note), not a 50-page wiki that is unreachable if the server is down. It must cover: how to access backups, how to reprovision the server, contacts for key service providers, and DNS access credentials. Modern SaaS platforms (Vercel, Netlify) absorb part of the DRP by eliminating the server management layer entirely.
