Snapshot
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Recording the complete state of a system at a specific point in time. It is not a backup (copy), but a 'frozen image' of that moment, used for subsequent recovery or analysis.
SCAFFOLDING EFFECT
Reduce cognitive load
Freezing and preserving the state. Before performing high-risk operations (such as negotiations, surgery, code refactoring), take a 'snapshot' (record all current conditions, commitments, and states). If the operation fails, you can quickly roll back to the snapshot point rather than rebuilding from the ruins.
Anchor fast decisions
Snapshot: At a certain moment, make a consistent copy of the system state (memory, data, file system) for backup, recovery, or analysis. The difficulty lies in capturing a 'instantaneous consistent' view without stopping the system (e.g., copy-on-write).
