How to Calculate Disaster Recovery

What is Disaster Recovery?

A disaster recovery calculator helps define and validate RTO (recovery time objective) and RPO (recovery point objective) targets. RTO is the maximum acceptable downtime; RPO is the maximum acceptable data loss. Together they determine backup frequency and standby infrastructure requirements.
