By that reasoning, backup isn’t redundancy because you’ll lose your data if the backup gets corrupted while restoring.
That said, there’s nothing wrong in redefining “redundant” to mean “having two or more duplicates”… you should however tell people if you do, to avoid misleading people that assume the dictionary definition.

RAID0 has no redundancy, but all of the other RAID options do have redundancy.
