If I were going to the dramatic step of implementing TSM file encryption, I would utilize a management class whose name made clear that encryption was employed, given that a vital key is needed to decrypt such files. In that way, simply seeing that a file was associated with that management class would indicate that it was encrypted. I would definitely *not* utilize an ordinary, pre-existing management class with encryption, as that's asking for a tremendous amount of future confusion - which is the last thing needed in a DR scenario.
