Backup

Backup: A copy of data or system states intended for recoveryRecoveryThe controlled restoration of systems, data, and business services after a disruption. following loss or an attack. The focus is on resilience and restarting operations after disruptions. This involves prioritized business processes, tested plans, robust backups, exercises, and clearly defined recovery objectivesRecovery ObjectiveA measurable target for the timing or data state of recovery after a disruption..

How it works and where it fits

Backup views security through the continuity and restoration of critical services. The question is not only whether disruption can be prevented, but which processes take priority, which dependencies they require, and which data states must be restored within defined periods. Technical systems and organizational procedures form a shared recovery chain.

Practical security relevance

Resilience can be demonstrated only through realistic testing. Backups need separate protection, recovery procedures must be documented, and responsibilities must be unambiguous. Exercises should include unavailable identity services, compromised administration paths, missing keys, and constrained communication. Measurable recovery objectives connect technical measures to actual business impact.
