Energize Your Workflow 2006 User Group Meeting May 7-9, Disaster Recovery - What it means to you Disaster Recovery (DR) is the ability to recover from a major interruption in operations within an acceptable amount of time, with an acceptable amount of data loss. The focus should be on data protection and recovery.
