Typical questions used to identify a required RPO level include: ‘How many transactions can you afford to lose?’ ‘Do you have a manual paper trail as a backup?’ and ‘Do you have compliance issues if you lose data?’
Recovery Time Objective (RTO) also plays a strong part in Continuity planning. RTO is defined as the target amount of time that it should take for systems to be restored. How long can your business last without being able to send or receive emails, answer the phone or take a customer’s order?
