The main aspect of every backup and recovery strategy is a balance of RTO and RPO objectives. They regard how quickly and precisely you will be able to get the data back if something goes wrong. In case of disaster, recovery time objective becomes one of the most valuable characteristics in the business planning.
RTO and RPO (recovery time objective and recovery point objective) are two key metrics that organizations must consider in order to develop an appropriate disaster recovery plan that can maintain business continuity after an unexpected event.
Although only one letter separates RTO from RPO, it’s important not to confuse or conflate these two metrics. Both help to determine maximum tolerable hours for data recovery, how often data backups should occur and what your recovery process should be. Both need to be considered when creating a disaster recovery plan.
