Redundancy, according to Dictionary.com, is defined as “…the provision of additional or duplicate systems, equipment, etc., that function in case an operating part or system fails…”

Redundancy as it relates to disaster preparedness is the practice of incorporating backup plans and/or gear items into an individual’s or group’s established preparedness strategy.

The concept of redundancy in disaster preparedness can be traced back to the military adage,” Two is one, one is none” which speaks to the idea that equipment and items carried by soldiers was prone to failure due to a myriad of reasons. One way to circumvent the loss of a broken or damaged piece of gear was to equip a backup piece of gear as a substitute.
