1.Identifies and priorities business processes based on criticality.
2.Establishes metrics to be integrated into the infrastructure and the SLAs
+ Service Level Objectives
+ RPO (Recovery Point Objective)
+ MTD (Maximum Tolerable Downtime) aka RTO (Recovery Time Objective)
+ RSL (Recovery Service Level ) is a percentage of how much computing power is necessary based on the percentage of the production system needed during a disaster.
3.RPO & RTO
+ Recovery Point Objective (RPO): Amount of acceptable data loss measured in terms of how much data can be lost before the business is too adversely affected.
+ RPO indicates the point in time a business is able to recover data after as systems failure,relative to the time of the failure itself.
+ Recovery Time Objective (RTO): Amount of systems downtime defining the total time of the disaster until the business can resume operations.
+ Quantities how much data loss is acceptable without grossly adversely affecting the business due to business transactions data.
4.Disaster recovery and continuity planning deal with uncertainty and chance
+ Must identify all possible threats and estimate possible damage
