We present a realistic model of next generation peer-to-peer (P2P) backup/storage systems where users have the ability, besides making the usual decisions, to select the peers they want to cooperate with. Under the circumstances we can anticipate the final state where the system ends up, and interesting conclusions can be drawn: selfish users will form coalitions based on their qualities. The assumed extension, compared to the existing P2P systems, introduces direct incentives for users to contribute more to the system, moreover it increases user fairness, not to mention the fact that it results in easier peer selection and data management techniques to be implemented.
