"Backup" is only too generic a term when you redefine it to mean whatever you wish as you appear to do. Lookup "Backup" in any dictionary and it will refer to creating a 'copy of data to guard against loss'
RAID does not create a copy of your data and so fails to meet the definition of being a backup. Even RAID-1 fails to meet this definition as it does not protect against data loss in the form of accidental deletion.
