Databasus for backup of PostgreSQL and MySQL

Databasus: Open Source Solution for Automated Backups of PostgreSQL, MySQL, MongoDB

Databasus provides automated backups for PostgreSQL (primary focus), MySQL, MariaDB, and MongoDB. One-command Docker deployment with support for local storage, S3, Cloudflare R2, Google Drive, Azure Blob, NAS, SFTP, and rclone. Notifications via Slack, Discord, Telegram, MS Teams, email, and webhooks. Data encryption, audit logs, project and access management.

Supports self-hosted and cloud databases, logical/physical/incremental backups with WAL streaming for PITR. Two modes: remote (direct connection) and agent-based (stream from the DB server).

Deployment Methods

Four installation options for different environments.

Shell Script

Automatic Docker installation and launch:

sudo apt-get install -y curl && \
sudo curl -sSL https://raw.githubusercontent.com/databasus/databasus/refs/heads/main/install-databasus.sh | sudo bash

Docker Compose

services:
  databasus:
    container_name: databasus
    image: databasus/databasus:latest
    ports:
      - "4005:4005"
    volumes:
      - ./databasus-data:/databasus-data
    restart: unless-stopped

Run: docker compose up -d.

Docker run

docker run -d \
  --name databasus \
  -p 4005:4005 \
  -v ./databasus-data:/databasus-data \
  --restart unless-stopped \
  databasus/databasus:latest

Kubernetes Helm

helm install databasus oci://ghcr.io/databasus/charts/databasus \

Renaming History

The project evolved from Postgresus 2.0, which was focused solely on PostgreSQL. After gaining over 1,000 stars on GitHub and community requests, support for MySQL, MariaDB, and MongoDB was added.

The rename was prompted by:

• Functional expansion beyond PostgreSQL.
• Violation of the "Postgres" trademark — since 2020, its use in names has been prohibited without fair use.
• Risk prevention (e.g., potential loss of Docker Hub pulls in unforeseen circumstances).

PostgreSQL is now tolerant of fair use, but the author opted for the neutral name Databasus for broader applicability.

Key Points

• PITR support via WAL streaming for PostgreSQL.
• Agent-based mode for backing up closed databases without external access.
• Encryption of all sensitive data and backups.
• Multi-tenancy: projects, users, audit.
• Quick deployment in Docker/K8s with no dependencies.
