Data Replication in OceanStore
U.C. Berkeley Master's Report, Technical
Report UCB//CSD-02-1217, November 2002
We present the design and implementation of the data replication
subsystem of OceanStore, a global-scale storage system. Our system
automatically replicates data on or near the the client machines where
the data is accessed, in order to improve locality, scalability, and
availability. These replicas cooperate to share data and disseminate
updates securely and efficiently.

Replicas also provide a flexible read
interface that allows applications to relax data consistency in
exchange for improved performance and availability. This interface
also supports retrieval of arbitrarily old versions of client data
