Recovery point objective

Recovery point objective

Recovery Point Objective (RPO) describes the acceptable amount of data loss measured in time.

The Recovery Point Objective (RPO) is the point in time to which you must recover data as defined by your organization. This is generally a definition of what an organization determines is an "acceptable loss" in a distressed situation. If the RPO of a company is 2 hours and the time it takes to get the data back into production is 5 hours, the RPO is still 2 hours. Based on this RPO the data must be restored to within 2 hours of the disaster.

Example: If there is a complete replication at 10:00am and the system dies at 11:59am without a new replication, the loss of the data written between 10:00am and 11:59am will not be recovered from the replica. This amount of time data has been lost has been deemed acceptable because of the 2 hour RPO. This is the case even if it takes an additional 3 hours to get the site back into production. The production will continue from the point in time of 10:00am. All data in between will have to be manually recovered through other means.

The RPO in conjunction with the Recovery Time Objective (RTO) is the basis on which data protection strategy is developed.
