The recovery service level (RSL) is a percentage measure of the total typical production service level that needs to be restored to meet BCDR objectives in the case of a failure.
The value that refers to the percentage of production level restoration needed to meet BCDR (Business Continuity and Disaster Recovery) objectives is RSL (Recovery Service Level).
Recovery Service Level is a measure of how quickly an organization can restore its critical IT systems and applications after a disruption, and is expressed as a percentage of the organization's normal service level. For example, if an organization has an RSL of 90%, it means that after a disruption, it aims to restore service to 90% of its normal level as quickly as possible.
RPO (Recovery Point Objective) refers to the maximum amount of data loss that an organization is willing to accept in the event of a disruption. For example, if an organization has an RPO of 4 hours, it means that it can tolerate up to 4 hours of data loss in the event of a disruption.
RTO (Recovery Time Objective) refers to the maximum amount of time that an organization is willing to accept for the recovery of its critical IT systems and applications after a disruption. For example, if an organization has an RTO of 2 hours, it means that it aims to restore service within 2 hours of a disruption.
SRE (Site Reliability Engineering) is a methodology for designing and operating large-scale, highly available software systems. It focuses on automating operations tasks, monitoring system health, and improving system reliability and performance. It is not directly related to BCDR objectives.
In summary, the value that refers to the percentage of production level restoration needed to meet BCDR objectives is RSL (Recovery Service Level).
