Recovery Time Objective (RTO)

The maximum acceptable downtime for a system or service before business impact becomes unacceptable.

Risk & ResilienceAlso called: "rto"

RTO defines how quickly you must restore operations after a disruption, guiding technology investments and recovery strategies.

Why it matters

  • Determines the speed and complexity of disaster recovery solutions.
  • Influences architecture decisions (hot standby, warm backup, cold storage).
  • Sets stakeholder expectations during incident response.
  • Drives runbook design and team readiness.

How to determine RTO

  • Identify revenue loss per hour of downtime for each critical system.
  • Review SLA commitments to customers and partners.
  • Factor in compliance penalties for extended outages.
  • Consider cascading dependencies between services.
  • Test recovery procedures regularly to validate RTO targets are achievable.
