What term describes the duplication of computer equipment and data for backup?

The term that best describes the duplication of computer equipment and data for backup is redundancy. Redundancy refers to the practice of having additional or spare systems, components, or data in place to ensure that in the event of a failure or loss, operations can continue without interruption. This can involve having multiple copies of data stored in different locations, utilizing backup systems, or having alternative equipment ready to take over should the primary system fail.

This practice is crucial in IT and data management as it enhances reliability and ensures data availability, thus enabling organizations to mitigate risks associated with system failures, data loss, or disasters. By implementing redundancy, organizations can protect their critical information and maintain continuity of operations.
