Coolify is an open-source, self-hosted PaaS for deploying applications and databases. Its backup engine ships with first-class support for S3-compatible object storage, so PostgreSQL backups can flow straight to Vultr Object Storage, AWS S3, Wasabi, Backblaze B2, or MinIO without extra tooling. This guide deploys a PostgreSQL service in Coolify, schedules automated backups to an S3 bucket, simulates accidental data loss, and restores the database from the backup. By the end, you'll have a working backup-and-restore loop covering a self-hosted Postgres service in Coolify.
Prerequisite: A running Coolify install (2 CPU cores, 4 GB RAM minimum) and an S3-compatible bucket with access key and secret key.
