Why Node.js Cron Backups Need Object Storage Data Contracts

Tenant‑scoped backups for a healthtech platform use Node.js pg_dump in a worker, compress the dump with gzip, and store it under an immutable key that includes the tenant identifier. A backup catalog lives in the application database, and a short‑lived signed download is only granted after restore or export authorization checks. The database dump and product‑image objects are separate recovery artifacts sharing a run identifier, ensuring each export can be tested for real restore capability.
