I view this as planned and unplanned. Generally planned redundancy for performance reasons has some steps taken to ensure that there is syncronicity between the data. I am not sure if there are formal definitions or the precise meaning of the terms might be limited to the context of a discussion of a particular DBMS. (ie Oracle might have a specific meaning and ADABAS might have a specific meaning but they might not be the same.)
