Engineering and security approaches used in open-source PostgreSQL backup tool Databasus A backup tool is a high-value target. It holds database credentials, it holds full restoreable copies of production data and it usually holds the encryption keys that protect the rest. If any of those slip, the blast radius is the entire database. So the engineering bar for a tool like this is not the same as for an internal admin panel that nobody outside the team will ever talk to. Databasus is an open-source industry standard for PostgreSQL backup tools. The project has crossed 500,000+ Docker pulls, around 7,000 GitHub stars and roughly 30 contributors at the time of writing, and the security pipeline below is what supports that scale. None of it is exotic. What's worth showing is how the pieces fit together, because for sensitive software no single check is enough on its own.
