Efficient file synchronisation

Abstract

A method for efficiently synchronizing a file between a first node and one or more second nodes, each of which is configured with an initial file. The method comprises applying at the first node one or more first transforms to the file; preparing a descriptor of the one or more first transforms applied to the file; transmitting the descriptor to the one or more second nodes; decoding the descriptor to extract one or more second transforms at the one or more second nodes; and executing the one or more second transforms on the initial file located to obtain a semantically equivalent file at the one or more second nodes. The one or more second transforms may be identical to or different from the one or more first transforms. The initial file configured on the first and second nodes may be binary equivalent or semantically equivalent.
