Abstract
Embodiments of the invention concern a method of redundant data storage in a peer-to-peer overlay network (N), and a network node () and a computer program product to execute said method. The peer-to-peer overlay network (N) comprises a plurality of nodes (). A physical hardware on which a first node () of said plurality of nodes () runs is identified. At least one second node () of said plurality of nodes () which runs on a different physical hardware than the first node () is determined. A replica () of data for which the first node () is responsible is stored on the at least one second node () in addition to or instead of storing a replica () of the data on a next logical node () of the first node, whereby said next logical node () is a node of the plurality of nodes () neighboring the first node () with regard to a topology structure of the peer-to-peer overlay network (N).
