Abstract
A system and method are provided for peer-to-peer distributed file storage in a network of connected clients. The method transmits data file peer-storage information from a first peer node to a network-connected backup manager. The backup manager creates a mapping plan, for mapping data file segments to a peer group, which typically includes a plurality of network-connected peer nodes. The backup manager transmits the mapping plan to the first peer node. The first peer node distributes the data file segments to the peer group in accordance with the mapping plan, for storage in tangible memory media. Typically, the first peer node accepts a data file and encrypts the data file. In one aspect, the backup manager creates a mapping plan for distributing (n+x) erasure-coded segments. After receipt of the mapping plan, the first peer node creates the (n+x) erasure coded file segments in preparation for distribution.
