# Deploy and Host bun-pg-s3-backup on Railway

A simple Bun script with a Railway bucket to enable blazingly fast automatic backups for your Postgres databases. Run this with a Railway cron schedule and configure the backup retention duration for a fast, easy and cost-efficient backup solution.

This is a fork of Railway's [postgres-s3-backups](https://github.com/railwayapp-templates/postgres-s3-backups) repository which replaces Node with Bun and interacts with the Railway bucket using Bun's native S3 bindings for the best performance.

## About Hosting bun-pg-s3-backup

Set up your Postgres database in your Railway project, then deploy this template into your project with the internal database URL set. Finally, set a cron schedule on the Bun service and let the cron job takes care of everything by itself.

The service has a default backup retention duration of 7 days. Customize this in the variables section.
