PEERSTORE: A PEER-TO-PEER BACKUP SYSTEM

Abstract

The vision of this thesis is to focus on designing a Peer-to-Peer backup system to be suited into large unstable networks. Peer-to-peer backup, the implementation of a data backup service on top of a peer-to-peer network has received research attention in recent years. This thesis tries to concentrate on the use of Peer-to-Peer backup in the Internet, with a large number of anonymous users. The thesis offers both a general analysis of the requirements and issues of peer-to-peer backup, and a new design for such a system. Existing systems are introduced and their suitability for Internet is evaluated, before we present our own novel peer-to-peer backup scheme PeerStore. PeerStore offers better performance by separating the tasks of data placement and metadata management, its improvements are shown by running the experiments in real networks.
