Background

i. The criteria to efficiently and effectively resume normal business operations after a disruption.
a. Within this document, the following definitions apply:
i. *Business impact analysis/assessment* - an exercise that determines the impact of losing the support of any resource to an enterprise, establishes the escalation of that loss over time, identifies the minimum resources needed to return to a normal level of operation, and prioritizes recovery of processes and the supporting system.
i. *Disaster recovery plan* - a set of human, physical, technical, and procedural resources to return to a normal level of operation, within a defined time and cost, when an activity is interrupted by an emergency or disaster.
i. *Recovery time objective* - the amount of time allowed for the recovery of a business function or resource to a normal level after a disaster or disruption occurs.
i. *Recovery point objective* - determined based on the acceptable data loss in the case of disruption of operations.
