This is a rubbish smackdown. Where's the drama? Where's the bit where one of these backup utilities gets voted off the island? Here's the thing, though: over the last month or so, we've reviewed three very powerful applications that broadly do the same thing. They all back up your data to external hard disks, and they all create ways that you can startup your Mac again even if your internal drive dies on you. Carbon Copy Cloner, SuperDuper, and ChronoSync are surely the leading applications in this, and they are certainly needed. We just wouldn't be doing our job if we didn't pitch them against each other to help you pick one.
