| Strategy | Example | |----------|---------| | | N+1 power, RAID storage, redundant network links | | Diversity | Different telecom carriers, cloud regions | | Failover | Active-passive or active-active data centers | | Backup | Onsite + offsite + cloud backups (aligned to RPO) | | Alternative processing | Manual workarounds, cold/warm/hot sites | | Data replication | Synchronous (short RPO) vs. asynchronous | iso 27031 disaster recovery

| Principle | Description | |-----------|-------------| | | ICT recovery targets must match business continuity requirements (RTO/RPO). | | Resilience by design | Build redundancy, diversity, and failover into ICT architectures. | | Incident response integration | ICT incident handling must feed into business continuity invocation. | | Continuous improvement | Regular testing, review, and updating of ICT readiness measures. | "The failover link to the backup site is
