Rapid increases of user data from terabytes to petabytes have created new challenges in data archiving. Modern data archive systems require higher adaptivity, reliability, and performance than traditional data archive systems can provide. Recently Hierarchical Storage Management (HSM) has been applied to a data archive that stores data in a multi-level storage system according to access frequency. In this paper, we describe the design and implementation of a novel HSM-based data archive system called T-Archive, which can meet the above requirements for order-of-magnitude scaling of storage.
