HathiTrust is intended to provide persistent and high availability storage for deposited files. In order to facilitate this, the initiative’s technology concentrates on creating a minimum of two synchronized versions of high-availability clustered storage with wide geographic separation (the first two instances of storage will be located in Ann Arbor, MI and Indianapolis, IN), as well as an encrypted tape backup (written to and stored in a separate Ann Arbor facility).
Each of these storage or tape instances is physically secure (e.g., in a locked cage in a machine room) and only accessible to specified personnel. Each separate storage system is also equipped with mechanisms to provide mirrored management and access functionality, and employ 100% data redundancy in an effort to prevent data loss.
