Time Machine backup in Mac OS X is arguably the most rock solid consumer-friendly backup and restore solution. It's one of the big reasons I stick with Mac. FileVault full disk encryption is also pretty solid. I won't speak to its efficacy against the most notorious adversaries (e.g. Governments) but it will reliably thwart any adversary most people would ever actually care about. Apple's firmware passwords seem to work well, though I have no idea how robust they are. It's just a damn shame it's nowhere as easy to set up as the iPhone equivalent. (Just turn on Find My iPhone and that hardware is activation-locked to your iCloud account.)
