Depends on your drive model. The more recent wii's don't read any backup discs, so it's useless for those. If you have an old wii (bought before...mid 2008, iirc), it may or may not work. I've heard reports on ppl whose wii's played everything they threw at it while others were very picky (mine only likes verbatim discs...and only if I insert them very gently and stroke my wii a bit once she accepts it). In short, I'd say "it is unlikely".
