Cloud Task Replica - Towards a Preservation Strategy

Abstract

This presentation will share our experience in the design of a replication management system which attempts to go beyond standard IT backup practices, which protect only against isolated, local, technical or procedural failures. The design attempts to model the problem in a manner flexible enough so that replication can be entirely self-managed within a repository, by a network of peer institutions, or service providers, or any combination of the above, or indeed evolve from one to another. It also envisions replication relationships among heterogeneous repository systems. The system utilizes cloud infrastructure and services for both content storage and replication management, and as such attempts to address some of the inherent scaling and resource allocation issues that typically accompany large replication efforts.
