Hard drives are bound to fail, as we've recently discussed
, so of course having a backup plan is essential. There's plenty of way to spread the risk amongst multiple drives in your home, but what about online backup? So much is moving to the magical cloud and data speeds are increasing across the board (though no word on if/when we'll see speeds like Japan) that it's becoming increasingly practical to have a remote backup. Even if you trust drives in your own home more (and we agree, that's definitely a route to go) an online backup isn't very expensive and protects your data from things like fire, flood or freak accidents. Mozy
all provide effective online backup services.
