rostislav_dugin Sunday, December 28, 2025
I had a post in the start of December about Postgresus 2.0: self hosted tool for PostgreSQL. Since then the project changed the name and added support of other databases: MySQL, MariaDB and MongoDB.
Website - https://databasus.com
GitHub - https://github.com/databasus/databasus
Main features:
- Scheduled backups for multiple PostgreSQL, MySQL, MariaDB and MongoDB databases
- Storage to S3, Cloudflare R2, Google Drive, Azure Blob, NAS, SFTP, rclone, etc.
- Notifications about backup status via email, Telegram, Slack, Discord, MS Teams and customizable webhooks
- Works with both self-hosted and managed PostgreSQL (RDS, Cloud SQL, etc.)
- Runs as a single Docker container or via Helm on Kubernetes, can be installed via script
- There are workspaces and role-based access with audit logs
