Short answer
Keeping only the latest copy hides what changed and why. Version history makes documents, reports and plans recoverable.
What you need
- A meaningful version note
- A distinction between source and result
- Restore-as-new-version behavior
Step by step
- Preserve the current version before a material change.
- Record what changed and why in a short note.
- Restore an older state as a new version without erasing later history.
Common mistakes
- Treating every keystroke as a version
- Leaving no note
- Deleting later history during restore
Safety and verification
Manage personal data retained in versions according to the storage and deletion policy.
