The term 'High resiliency' refers to the capacity to absorb or avoid damage without suffering complete failure. A highly resilient organization can continue to operate despite adverse conditions, and it achieves this through redundant systems, effective disaster recovery plans, and other continuity strategies. 'Fault tolerance' refers to a system's ability to continue operating properly in the event of a failure of some of its components. 'Redundancy' is the duplication of critical components or functions of a system to increase reliability. 'Sustainability' refers to the ability to maintain certain environmental, economic, and social conditions indefinitely; though important, it does not directly address the continuity of operations after a disruption.
