Acquisition and Processing of Disk Images to Further Archival Goals

Disk imaging can provide significant data processing and information extraction benefits in archival ingest and preservation workflows, including more efficient automation, increased accuracy in data triage, assurance of data integrity, identifying personally identifying and sensitive information, and establishing environmental and technical context. Information located within disk images can also assist in linking digital objects to other data sources and activities such as versioning information, backups, related local and network user activity, and system logs. We examine each of these benefits and discuss the incorporation of modern digital forensics technologies into archival workflows.
