What is RPO & RTO?
Recovery Point Objective (RPO) is the time that data loss is acceptable. Recovery Time Objective (RTO) is the duration of time and service level which a business process must be restored after a disaster in order to avoid unacceptable consequences associated with a break in continuity. The RPO in conjunction with RTO is the basis on which data protection strategy is developed. 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. All data in between will have to be manually recovered through other means.
