Questions & Answers

As answered by people managing Restora.cc and Project Euler.

Which are the primary technologies used for building your product?

Restora.cc's answer

NestJS, Node.js, Notion API, Google Drive API, S3, TypeScript, React

What makes your product unique?

Restora.cc's answer

Restora doesn't just download your Notion workspace — it verifies the backup actually restores. Most backup tools stop at "we have a copy." Restora runs a free Drift Audit and Restore Rehearsal that confirm your data comes back exactly as it was: relations reconnected, rollups recomputed, views intact. It's built store-nothing — your backup goes straight to your own Google Drive or S3, never sits on our servers.

Why should a person choose your product over its competitors?

Restora.cc's answer

Most Notion backup tools give you a JSON dump and hope it works when you need it. Restora proves it works before you ever need it — free, automatic drift detection catches what changed since your last backup, and a one-click restore rehearsal shows you the exact recoverability verdict. It also handles what other tools miss: multi-level rollup chains, self-referencing relations, and full page hierarchies, not just flat database rows.

How would you describe the primary audience of your product?

Restora.cc's answer

Teams and individuals running critical work in Notion — databases with relations, rollups, and workflows they can't afford to lose. Particularly founders, ops teams, and agencies who've been burned by an accidental delete or a messy migration and want real disaster-recovery guarantees, not just a backup button.

What's the story behind your product?

Restora.cc's answer

Restora started from a simple, uncomfortable question: if someone deleted your Notion workspace right now, could you actually get it back — relations, rollups, and all? Most backup tools couldn't honestly answer yes. Restora was built to close that gap: not just backing up data, but proving it restores faithfully, with the same relational integrity you built with.
