Checksum Backup

Technique

A preservation and delivery technique for checking whether important files have copied correctly and remain unchanged.

Description

Checksum backup uses a digital fingerprint to confirm that a file has not changed during copying, transfer, or storage. This is useful when builds, media files, capture data, archives, or installation packages must be moved safely. It helps the team catch silent file corruption before it becomes a delivery problem.

Typical Use

Used during platform packaging, archive work, data wrangling, installation delivery, build handoff, media transfer, and long-term preservation.

Scope Note

This technique may include checksum generation, copy verification, file manifests, backup logs, drive labels, storage notes, and recovery checks.
