Databasus is a free, open-source tool for self-hosted database backups, focused primarily on PostgreSQL. It also supports MySQL, MariaDB and MongoDB. PostgreSQL options include logical backups, physical full and incremental backups, and WAL streaming for point-in-time recovery; physical, incremental and WAL backups require PostgreSQL 17 or newer. Schedules can run hourly, daily, weekly, monthly or on cron intervals. Destinations include local storage, S3-compatible storage, Cloudflare R2, Google Drive, Azure Blob Storage, NAS, FTP, SFTP and rclone. Databasus can periodically restore a recent backup in a temporary database container and report the result. Team tools include access management, separate teams and projects, and audit logs. The maker says credentials and backup files use AES-256-GCM encryption, while database access is read-only and requires SELECT permissions. Deployment options include a Linux script, Docker, Docker Compose and Helm for Kubernetes. The listed plan is 0.00 USD per free under the Apache 2.0 license, with all described features. Minimum requirements include one CPU core, 500 MB RAM and 5 GB installation storage, plus backup storage.
