Project (Out of Band Synchronisation)

Description

Provide a solution for performing offsite back ups, where directly transferring the data is impossible or incredibly expensive, however regular transport between locations is avaliable and at least 1 operation computer is transferred between sites.

Goals/Requirements

• Synchronise data using out of band data transfer.
• Support extremely slow, high capacity links. (80+GiB with 1 week latency)
• Support multiple transfer agents.

Initial Design

• Make use of [1] infrastructure (espically networking code).
• Use the code generator git://git.scottnz.com/generator.git/ to generate OO code from a design spec.
• Split system into 3 parts: metadata store, data servers, and transfer agents.
