Disaster Recovery

Resilient

The capability of remaining or returning to a normal situation after an event by having multiple ways of performing a function.  This may include people, processes or technology.  Generally speaking, this means there would be no single point of failure that could stop a process.

Disaster Recovery

Restarting technology operations after an outage using processes, policies and procedures prepared for recovery or continuation of mission-essential technology infrastructure after a disaster. 

These processes are found in a DR Plan.  DR is a subset of business continuity and COOP.

The three principal goals of DR are to:

Save data,
Save hardware, software and facilities
Resume critical processes/restore data.

Continuity of Operations

Continuity of Operations involves the activities associated with the identification of critical systems and processes, and the planning and preparation required to ensure that these systems and processes will be available in the event of a catastrophic event and involves the internal actions necessary to develop a plan for resuming operations after a catastrophic event occurs. This can include Contingency Planning, Continuity of Operations and Service Recovery work.

Business Continuity

The activities performed by the agency to ensure critical functions are available to entities needing access to those functions.  Business continuity is related to restoring normal day-to-day functions in the event of service disruptions. Business continuity planning is different than disaster recovery planning.
