Well, there's no such thing as an absolutely fail proof solution, no matter how well it's implemented. Only the mean time between failures increases (MTBF). 😀 😛TM isn't the best option out there! It's not fool proof! And it's still backing up on mechanical devices which can still fail. So don't rely on it completely. There are many users here, who've had a bad experience with TM.. go search the forums.
