Warm backup using snooping
Danny Dolev, Dalia Malki, Yuval Yarom · 2002
Local area networks use a broadcast media to transfer messages between hosts. This allows for network snooping by unlisted parties. This paper proposes a novel way for cheaply replicating services in a local area network via snooping. We present a tool for the warm backup of files that employs network snooping for data dissemination. The tool allows for a selective replication of files in the system. The use of snooping significantly reduces the overhead of file replication. Operations on non-replicated files suffer only a slight overhead.>
