Recovery point objective
From Wikipedia, the free encyclopedia
Recovery point objective (RPO) describes the acceptable amount of data lost measured in time.
The Recovery Point objective RPO is time of data loss that is acceptable. If the RPO of a company is 2 hours and the time it takes to get the system back into production is 5 hours, the RPO is still 2 hours.
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.
