Survey of Digital Infrastructures and ServicesCONUL DIGITAL SERVICES & INFRASTRUCTURE SUB -GROUP
CONUL Members
DSI Sub-group - Terms of ReferenceIdentify and develop major issues and strategic priorities.
Identify and develop opportunities for cooperation and collaboration among CONUL libraries.
Identify and develop key relationships outside of CONUL.
To continue to identify affinities or overlap with other CONUL groups’ areas of enquiry.
To continue to identify an appropriate structure for CONUL to address the topic in the longer term.
To identify and track work underway, existing infrastructures and digitisation resources, pertinent expertise, policies etc., as well as additional relevant issues.
To consider a range of issues relevant to OPEN ACCESS.
Survey•Gather information about existing repository or archival information systems in use by CONUL libraries
•Based around the OAIS Reference Model• OAIS Functional Model (ingest, archival storage, disaster recovery, access, data management,
preservation planning, resourcing & skills)
• OAIS Information Model (SIPs, AIPs, metadata)
• Operating Environment (community, reporting, strategic planning)
•Survey yielded 14 responses from 10 institutions

Storage
•Storage procured by the library’s parent institution (57.1%)
•Rest split between local, hosted and third party-managed
•No institution using cloud storage as the main object store
•Canonical copy mostly stored offline (CDs/DVDs, disconnected external HDs)
•57.1% (8/14) using SAN storage 28.6% (4/14) using NAS
•Content managed in TB: 3 institutions > 10TB, mostly < 1TB
•71.4% (10/14) allow the repository to arrange data on filesystem (Akubra/Modeshape)
Backups
•Online backups 64.3%
•Nearline 71.4%
•Offline 42.9%
•Many have an instance of each, demonstrating multiple levels of backup policies
•Regular test of backups: 21.4% (3/14) regularly test, 42.9% (6/14) no schedule
•78.6% back up AIPs offsite
•50% (7/14) are continuously replicated to redundant copy, immediately available

Conclusion•Technology aspects are in hand• Infrastructure
• Storage
• Backups
•Data Preservation is not considered a priority
•Room for improvement on all aspects
•All at the early stages
•Opportunities to share skills – not “reinvent the wheel”
•Survey results to be published on Github
