Recovery Point Objective (RPO) is focused on defining the maximum acceptable amount of data loss measured in time. In the context of a disaster recovery plan, RPO is used to determine how often data should be backed up. It reflects the age of the files that will need to be recovered from backup storage to resume operations without significant loss. An RPO with a smaller time frame would necessitate more frequent backups to meet the stricter requirement. A Disaster Recovery Plan, while important for overall recovery strategy, is not a specific metric. Recovery Time Objective (RTO) is the targeted duration to restore services but does not directly relate to the amount of data loss that's acceptable.
