Morphology
redundant = redund + ant
Although the sense 'duplicated/backup' is semantically related to being 'extra', the word's parts are not analyzable by typical learners (Latin stem + -ant), so the meaning cannot be reliably inferred from the morphemes.
Etymology
Redundant also keeps the idea of 'extra' from the Latin redundare ('to overflow'), and that helps here: a redundant system has extra or duplicate parts as a 'backup' ready to keep things working if one part fails.
