Redundancy is the act of having more than one copy of something.

You should have more than one controlfile for your database - that is a redundant copy.
You should have more than one log file group (and more than one member per group).

If you have the same data element repeated more than once in a row, that would be data redundancy.  (Or I suppose if you have the same row stored in more than one table).
