By the same reasoning, why would you pay extra for a German car when you could drive a Daewoo or even ride a bike? (apologies to any Daewoo-driving readers and cyclists). You can also get "online backup" for zip with Google and others but in the end you get what you pay for.

From my reading, Data-inCrypt are providing a quality-leading, all-inclusive service for a particular segment, and the others you mention are aiming to be price-leaders, i.e. competing in a different space.
