(For complete details about my suggested strategy, including the steps to create a bootable duplicate, see “ Take Control of Backing Up Your Mac.”) Together, this combination can protect your data against almost any disaster, while making recovery as painless as possible.

In this first installment of FlippedBITS, I want to look at what happens when you boot your Mac from a duplicate (or “clone”) of your startup disk.
