Backup and Disaster Recovery

Plan for the worst case: the database is gone, the host is down for a week, the deploy was poisoned, ransomware encrypted everything. The skill is in advance preparation, not reaction.

When to use

• Setting up backups for a new system
• Reviewing and validating backup architecture
• Defining RPO (recovery point objective) and RTO (recovery time objective)
• Running a disaster recovery drill
• Diagnosing gaps after an incident
• Planning for ransomware, data corruption, or insider threats
• Migrating to a new platform (DR planning belongs in the migration plan)
