BackupDrill

BackupDrill backs up a Supabase project into an S3, R2, B2 or Wasabi bucket you own: the Postgres database, plus Storage files once you add the project's S3 keys. Then it checks that the backup actually restores.

Paid plans restore the latest snapshot into a throwaway Postgres every week, check the table count, that populated tables came back non-empty and a sample of Storage file checksums, and email you the report. The Free plan covers one project with weekly backups and one restore drill on the first backup, no card needed. Paid plans start at $19/month.

The backup engine is an open-source MIT CLI.
