VDCD510 Objective 2.6 – Build Recoverability Requirements into the Logical Design

RTO & RPO
During the business continuity plan creation it is necessary to define the key metrics of recovery point objective (RPO) and recovery time objective (RTO). These two terms are used to define how fast a backup can be restored and the amount of data loss.

Recovery Time Objective (RTO): The time it takes to recover from a data loss event. This is the amount of time while the systems or service is unavailable.

Recovery Point Objective (RPO): The amount of time between backups. Leads to the possible amount of data loss.

Disaster Recovery and Business Continuity

Disaster recovery refers to previously defined steps taken by administrators to resume services or systems after a disaster event.

Business continuity is a high level overview of processes to ensure that an organization can resume their business after a disaster.
