Morphology

redundancy = redundant (transparent) = redundant + ancy

The technical sense (extra components or duplication for reliability) is a straightforward extension of 'redundant' meaning 'extra' or 'surplus'.

Etymology

The word redundancy comes from Latin parts re- ('again') and undare ('to flow'), giving the image of an 'overflow' or extra. So in systems, redundancy means extra parts or backups that keep things working if one part fails.
