RTO and RPO are two important metrics used in disaster recovery and business continuity planning. RTO stands for Recovery Time Objective, which is the duration of time within which a business process must be restored after a disaster to avoid unacceptable consequences associated with a break in continuity. RPO stands for Recovery Point Objective, which refers to the maximum length of time permitted that data can be restored from, which may or may not mean data loss. In other words, RPO is the age of the files or data in backup storage required to resume normal operations if a computer system or network failure occurs. The difference between RTO and RPO is that RTO deals with the time to recover from a disaster, while RPO deals with the maximum amount of data loss. Both RTO and RPO are critical components of a disaster recovery plan, and they should be carefully considered and set based on the specific needs and requirements of a business.
