Serious question: why not use Backblaze to backup your important things? Because their homepage says: As low as $3.96/month per computer for unlimited data . I consider that to be an unmaintainable low price, and their "unlimited data" claim really puts me off. My files are too important to me; I couldn't even consider going with them.

In case you didn't know they invented the "Backblaze Pod" to reduce storage costs.

Even if you manage to upload 1 TB to their servers, they still don't lose money…
Fair enough. For me, though, there are so many possibilities for things going wrong when it comes to storage, I'd rather not trust it to a company trying to squeeze a profit from taking in a few dollars a month - and that's before processing costs.
Also, why would I go for the cheapest option when I get so much greatness for the equivalent of buying a few coffees/beers? It's not mega money by the majority of people's standards.
