Explanation
Recovery-Time Objective (RTO): The time within which systems and applications must be recovered after an outage. It defines the amount of downtime that a business can endure and survive. Some examples of RTOs and the recovery strategies to ensure data availability are listed RTO of 72 hours: Restore from tapes available at a cold site. RTO of 12 hours: Restore from tapes available at a hot site. RTO of few hours: Use disk-based backup technology, which gives faster restore than a tape RTO of a few seconds: Cluster production servers with bidirectional mirroring, enabling the applications to run at both sites simultaneously.
