The document discusses implementing high availability for mission critical databases. It is important for mission critical databases that support services with direct impact on revenue, reputation, safety, and compliance. True availability relies on people, process, and technology. The current situation involves efficient backup/recovery that meets recovery time and point objectives for most systems, but mission critical systems require higher availability. A business impact analysis can help set appropriate recovery objectives and guide appropriate spending to achieve high availability for mission critical databases through redundancy, failover, and disaster recovery.
