Recovery-time-objective (RTO) is a disaster recovery parameter specifying the maximum acceptable duration of service disruption after a failure event. It defines the target time by which systems, processes, or data must be restored following an incident. RTO is determined through business impact analysis that weighs the cost of downtime against the cost of recovery resources. It is enforced by recovery procedures, redundant systems, and failover mechanisms that operate to restore service within the defined window. [formal: recovery time objective | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]
