Abstract
A method for use in a distributed storage system having a plurality of nodes, the method including receiving, at a source node, original data, encoding the original data into plurality of coded fragments using a linear code, transmitting at least a first one of the coded fragments from the source node to a first sink node. The method further includes receiving, at the source node, modified data, calculating, at the source node, a coded difference between the original data and the modified data, transmitting the coded difference from the source node to the first sink node; and recovering, at the first sink node, at least a first portion of the modified data using the coded difference and the at least a first one of the coded fragments.
