datahoarding

Datahoarding is the practice of collecting and retaining large amounts of digital data, often with minimal regard for organization or long-term usefulness. It typically involves local storage on personal devices, external drives, networked storage, or cloud services, and can include documents, images, video, audio, emails, software, and web archives.

Motivations vary. Some individuals seek preservation or fear losing access to information; others are motivated by nostalgia, curiosity, or the belief that data might prove valuable in the future. The appeal is amplified when storage costs are low and formats seem stable, though formats can become obsolete over time.

Datahoarding is characterized by high volume, diverse formats, and inconsistent metadata, often with multiple identical copies scattered across devices. Practices may range from casual backups to extensive duplication, with limited indexing or lifecycle management. Techniques such as deduplication, archiving, and offline storage are used but not always applied consistently.

Risks include wasted storage space, increased time spent organizing or searching, data rot, and vulnerability to hardware failure. Privacy and security concerns arise when sensitive material is under-protected or shared without awareness. Legal or organizational retention policies may be violated by excessive retention of personal data.

Mitigation focuses on data lifecycle management: regular curation and deletion of unnecessary files, consistent metadata, centralized indexing or catalogs, retention schedules, encryption, and clear ownership. Some institutions pursue data governance to balance preservation with usability and cost. Datahoarding is a topic of interest in information science and psychology, reflecting broader questions about data preservation, information overload, and digital clutter.
