Engineering Data Backup & Version Control Guide

Classify engineering assets

• Separate source-controlled text/code from binary CAD models, controller projects, firmware packages and released documents.
• Identify authoritative masters, working copies and generated outputs so backup does not preserve ambiguity.
• Set recovery objectives based on the impact of losing recent engineering changes.

Version and backup controls

• Use change history and controlled releases where practical, and avoid relying on file names as the only version mechanism.
• Keep backup copies isolated from the primary working environment and protect administrative access.
• Include dependencies such as libraries, device profiles, licenses and environment configuration needed to restore a usable engineering system.

Recovery testing

• Test restoration of representative projects instead of treating successful backup jobs as proof of recoverability.
• Document who can restore systems and how emergency credentials are controlled.
• Review retention, access and offboarding as teams and projects change.
