Re: Defrag on a Mac
Not sure, Chris. Personally I don't use Time Machine. I clone my drives semi-regularly (about once every month or two) and there isn't anything that if I lost it in between those clones that I'd truly regret losing. If I put something important on my machine (say vacation pictures from France or an important work document) I usually have it on another media (like a USB stick, or something else). If I know it's only going to be on my Mac, I do another clone, or an incremental clone.
That way, I can restore from the clone to do the occasional defrag, which I routinely do, rather than have a separate Time Machine external HD and clone HD.
