The recovery point objective (RPO) is the age of files that must be recovered from backup for normal operations to resume if a computer system or network crashes as a result of hardware, software or failure of communication. The RPO is expressed backwards in time (that is, in the past) the moment when the failure occurs, and may be specified in seconds, minutes, hours or days. It was an important consideration in planning disaster (DRP).
Once the RPO for a given computer system or network has been set, determines the minimum frequency with which backups should be made. This, with the goal of recovery time (RTO), helps administrators choose the best recovery technologies in disaster and procedures. For example, if the CSP is an hour, backups must be made at least once per hour. In this case, external hard drives redundant May be the best solution in the event of a disaster. If the CSP is five days (120 hours), then safeguards must be carried out at intervals of 120 hours or less. In this situation, tape or compact disc recordable (CD-R) May be sufficient.
