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 [[2]] to generate OO code from a design spec.
  • Split system into 3 parts: metadata store, data servers, and transfer agents.
