<p>Embodiments of the invention concern a method of redundant data storage in a peer-to-peer overlay network (N), and a network node (211) and a computer program product to execute said method. The peer-to-peer overlay network (N) comprises a plurality of nodes (0, 20, 50, 87, 112, 140, 179, 200, 211, 223, 240). A physical hardware on which a first node (211) of said plurality of nodes (0, 20, 50, 87, 112, 140, 179, 200, 211, 223, 240) runs is identified. At least one second node (240) of said plurality of nodes (0, 20, 50, 87, 112, 140, 179, 200, 211, 223, 240) which runs on a different physical hardware than the first node (211) is determined. A replica (203) of data for which the first node (211) is responsible is stored on the at least one second node (240) in addition to or instead of storing a replica (203) of the data on a next logical node (223) of the first node, whereby said next logical node (223) is a node of the plurality of nodes (0, 20, 50, 87, 112, 140, 179, 200, 211, 223, 240) neighbouring the first node (211) with regard to a topology structure of the peer-to-peer overlay network (N).</p> |
