Can a Notion workspace owner verify that database relations and formulas survive a backup restore?

Verification goal

The owner wants to confirm that after exporting a Notion workspace and re‑importing the backup, database relations, formula properties, and permission settings remain functionally equivalent to the original state.

Constraints and uncertainty

Native exports flatten databases into Markdown, HTML, or CSV files that omit relation properties, formula definitions, and granular permission data, while the re‑import creates new pages with fresh IDs, breaking internal links unless they are rebuilt. Because Notion provides no built‑in backup integrity report or diff mechanism, the owner must decide what evidence constitutes a successful recovery.

Which metrics can be used to confirm that relation links are intact after re‑import? Does comparing row counts and property schemas suffice to detect missing formulas? How can permission sets be validated without a native diff tool?
