ATTIC is a near-line digital archival storage service for research, scholarly, and creative activity data, provided to those affiliated with the University of Nebraska. A near-line archival storage system is not typically directly accessible (i.e., mounted), and uses storage technology that can be accessed more rapidly than traditional data archival media (e.g., tape). HCC designed ATTIC to meet the requirements of a near-line archival storage system and be as affordable as possible. ATTIC is not designed for active use. Digital storage systems that provide online direct access are designed to be performant, can require specialized hardware, networking, and/or software, and are comparably more expensive to implement and maintain.
ATTIC uses the Zettabyte File System (ZFS), an open-source, widely used, flexible, and resilient filesystem. ATTIC’s storage configuration is designed to follow modern best practices and has multiple redundancies built-in for different types of potential failures. ATTIC is installed in climate-controlled facilities with restricted access and generator-backed redundant power. Copies of every file exist at two distinct geographic locations (Lincoln and Omaha), connected by a high-speed redundant network.
