Time Machine Failure

Alan Snyder describes a situation in which Time Machine doesn’t back up a new file (via Jonathan Rentzsch). Clever backup systems can be faster, but it’s also harder to verify that they’re doing the right thing. Time Machine is over three years old now, deployed on probably tens of millions of Macs, and from Apple. So you’d think it would be reliable, yet most knowledgable Mac users don’t seem to trust it, and my own experience bears this out.
