Two great Time Machine articles
Two great articles by Jeff Harrell where he explains in great details yet very simply how Time Machine works:
-
Instead of actually making copies of the already-backed-up files, it looks at them for a second, then goes, “Let’s not and say we did.”
Pretty darned close to perfection
But here’s the thing: If you’re not plugged in at 8:37 — say you’re sitting on your porch enjoying your morning coffee — Time Machine doesn’t mind. It doesn’t throw any big, annoying error message at you. It just says — silently, in the background, recorded only in a log file you really have to look for to find — “Okay, we can’t back up now; we’ll just back up again whenever this guy plugs in his external disk.”
And then … it does.
His blog layout is gorgeous too.
