I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

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).
