That’s not data redundancy - there’s still only one copy of your data.
Those are mitigations against loss of data due to loss of parity.

I think you’re confusing backup and redundancy. While I totally agree RAID1+ should not be considered backup, it absolutely is redundancy, as the same data is present on at least two disks (either on the form of the exact same data or something that can be used to rebuild the missing data).
