Backup strategies are a component of a larger disaster recovery strategy
It used to be the case that disaster recovery was an implied part of the backup process. I say it was implied because the devil really is in the details. Most people would say they had a plan and could recover from an outage but few ever actually tested for the sake of proving the model. The presumption back in the early days was that you could always recover from tape and that if your data was backed up then the ability to recover from a disaster was implied. Given the technologies at the time along with slow WAN connections it was always understood that the concept of disaster recovery using tape was at best going to be a “best effort” kind of recovery.
