Am I the only one who noticed a drastic slowdown in processing speed when backing up to Time Machine? I'm running a mac pro with 22 gig of ram and TM slowed it down so as to be unusable. I gave up on it. I'm glad some use it and find it to work well...it's a great concept and will save many people from experiencing a broken heart at loss of data.
