Recovery Time Objective (RTO) is the amount of time it takes for a computer or application crash or network disruption to resume normal operations and data
access. Recovery Time Objective is a metric that is incorporated into backup and disaster recovery strategies. It indicates how long it takes to recover lost data from backup or to provision entire systems after a crash. The RTO value is expressed in a unit of time, seconds, minutes, hours, or days, and is important for disaster recovery planning
(DRP). It depends onthe type of business, Information Lifecycle Management (ILM), data backup, availability and archiving
. The RTO value is a cost factor that represents the start-up of IT systems after a failure or the restart of production lines. In contrast to the Recovery Time Objective (RTO) is the Recovery Point Objective (RPO), which defines the reasonable data loss.
