How do I back up my dev database on App Platform?

Dev databases do not have a built-in backup feature becaues they are intended for pre-production workloads. However, you can create regular database backups by setting up a cron job in your app that uses pg_dump to export the database to another database or storage solution.

If you require a database with backup functionality for production workloads, consider using a DigitalOcean Managed Database.
