A system including a plurality of fractional-storage servers and a plurality of peer-to-peer devices. Substantially each of the servers and peer-to-peer devices stores less than a minimum amount of erasure-coded fragments needed to decode segments of streaming content. The system delivers at least the minimum amount of erasure-coded fragments needed to decode the segments of streaming content, from any group of the servers, or group of the servers plus peer-to-peer devices, that together store at least the minimum amount of erasure-coded fragments needed to decode the segments of streaming content. Optionally, the system supplements streaming capabilities of the servers during peak traffic periods by sending erasure-coded fragments stored on the peer-to-peer devices during the peak traffic periods.
