Recovery time objective (RTO) is the maximum acceptable duration permitted between an unfortunate loss or failure and the restoration of normal operations and services.
According to the RTO, the systems, applications or operations must be restored within a targeted time period after a disaster, to avoid unacceptable outcomes of the disruption.
So a business process must be recovered within this period of time.
It measures how much a failure affects the normal operations, applications and systems and RTO is measures in time units like seconds minutes hours or days.
In simple words RTO refers to the time you need to restore system, applications and data.
For instance a 2-hour RTO refers to restore and get operations or services back to running within 2 hours of the service failure or outrage.
