Definition
A Backup is an additional copy of data created to enable restoration after the primary data is lost, corrupted or unavailable.
Human Explanation
A Backup allows data to be recovered when the original information is accidentally deleted, damaged or lost.
Why it Matters
Regular Backups reduce the impact of failures, user errors, cyberattacks and disasters.
Conceptual Boundary
A Backup is not an archive or a guarantee of Business Continuity. It is one element of a broader Data Protection strategy.
Practical Perspective
A Backup has value only when the required data can be restored from it successfully.
