What is recovery time objective (RTO) and what is the difference between recovery time objective (RTO) and recovery point objective (RPO)?
Recovery time objective (RTO) refers to the maximum time that elapses from starting point of a disaster until the resumption of organizational services. RTO is measured in hours or days. Furthermore, it is the planned time required to restore systems to the point where it meets the minimum business requirements of the organization. Moreover, RTO is the amount of time that the organization can tolerate a critical system beind down before repaired. The RTO for each business requirement is the amount of time in which the organization expects to recover the systems in the event of the disaster. Other important business continuity concepts that should be considered in combination with RTO are RPO and MTD. Besides, the RTO should be less than the MTD.
Maximum tolerable downtime (MTD) is the maximum length of time a business function can tolerate a disaster before suffering irreparable damage. Moreover, Recovery point objective (RPO) refers to the maximum data loss from the point a disaster strikes. RPO is the amount of time that the organization can tolerate losing during the entire outage.
