In addition to redundancy, Sia has the concept of collateral, which is basically money locked in a smart contract that says "I'm willing to bet this money that I'm not going to lose your files". I.e. Hosts lose the money if they fail to store your files.
Different hosts have different amount of collateral, and it's both an important security measure as well as market mechanism.
Also, Sia is completely decentralized (unlike StorJ for example), so it can't be intervened with by anyone which might result in lost files.
