✨ Features

📦 Backup types

• Physical: file-level copy of the entire database cluster over PostgreSQL native incremental backups mechanism (read more)
• Full: a complete, self-contained copy of the cluster
• Incremental: stores only what changed since the previous full backup, so backups stay small and fast
• WAL streaming: continuously captures the database write stream, enabling Point-in-time recovery (PITR). Designed for disaster recovery and near-zero data loss
• Logical: native dump of the database in its engine-specific binary format (compressed, suitable for parallel restore)

🔄 Scheduled backups

• Flexible scheduling: hourly, daily, weekly, monthly or cron
• Precise timing: run backups at specific times (e.g., 4 AM during low traffic)
• Smart compression: 4-8x space savings with balanced compression (~20% overhead)

🧪 Restore verification (docs)

Databasus performs a real restore to confirm backups are usable, not just intact on disk or checksum check.

• Triggers: after each backup or on a flexible schedule (hourly, daily, weekly, monthly or cron)
• Real restore: spins up a database container, runs the restore and checks the restored size against the backup
• Report: lists every table with its row count
• Optional notifications: send the report or failure-only alerts through any configured notifier

🗑️ Retention policies

• Time period: Keep backups for a fixed duration (e.g., 7 days, 3 months, 1 year)
• Count: Keep a fixed number of the most recent backups (e.g., last 30)
• GFS (Grandfather-Father-Son): Layered retention — keep hourly, daily, weekly, monthly and yearly backups independently for fine-grained long-term history (enterprises requirement)
• Size limits: Set per-backup and total storage size caps to control storage usage

🗄️ Multiple storage destinations (view supported)

• Local storage: Keep backups on your VPS/server
• Cloud storage: S3, Cloudflare R2, Google Drive, NAS, Dropbox, SFTP, Rclone and more
• Secure: All data stays under your control

📱 Notifications (view supported)

• Multiple channels: Email, Telegram, Slack, Discord, webhooks
• Real-time updates: Success and failure notifications
• Team integration: Perfect for DevOps workflows

🔒 Enterprise-grade security (docs)

• AES-256-GCM encryption: Enterprise-grade protection for backup files
• Zero-trust storage: Backups are encrypted and remain useless to attackers, so you can safely store them in shared storage like S3, Azure Blob Storage, etc.
• Encryption for secrets: Any sensitive data is encrypted and never exposed, even in logs or error messages
• Read-only user: Databasus uses a read-only user by default for backups and never stores anything that can modify your data

👥 Suitable for teams (docs)

• Workspaces: Group databases, notifiers and storages for different projects or teams
• Access management: Control who can view or manage specific databases with role-based permissions
• Audit logs: Track all system activities and changes made by users
• User roles: Assign viewer, member, admin or owner roles within workspaces

🎨 UX-Friendly

• Designer-polished UI: Clean, intuitive interface crafted with attention to detail
• Dark & light themes: Choose the look that suits your workflow
• Mobile adaptive: Check your backups from anywhere on any device

💾 Supported databases

• PostgreSQL: 14, 15, 16, 17 and 18 (physical and logical)
• MySQL: 5.7 and 8 (logical only)
• MariaDB: 10, 11 and 12 (logical only)
• MongoDB: 4.2+, 5, 6, 7 and 8 (logical only)

🐳 Self-hosted & secure

• Docker-based: Easy deployment and management
• Privacy-first: All your data stays on your infrastructure
• Open source: Apache 2.0 licensed, inspect every line of code

📦 Installation (docs)

You have four ways to install Databasus:

• Automated script (recommended)
• Simple Docker run
• Docker Compose setup
• Kubernetes with Helm

📦 Installation

You have four ways to install Databasus: automated script (recommended), simple Docker run, or Docker Compose setup.

Option 1: Automated installation script (recommended, Linux only)

The installation script will:

• ✅ Install Docker with Docker Compose (if not already installed)
• ✅ Set up Databasus
• ✅ Configure automatic startup on system reboot

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

Option 2: Simple Docker run

The easiest way to run Databasus:

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

This single command will:

• ✅ Start Databasus
• ✅ Store all data in ./databasus-data directory
• ✅ Automatically restart on system reboot

Option 3: Docker Compose setup

Create a docker-compose.yml file with the following configuration:

services:
  databasus:
    container_name: databasus
    image: databasus/databasus:latest
    ports:
      - "4005:4005"
    volumes:
      - ./databasus-data:/databasus-data
    restart: unless-stopped
    healthcheck:
      test: ["CMD", "databasus", "healthcheck"]
      interval: 30s
      timeout: 5s
      retries: 3
      start_period: 60s

Then run:

docker compose up -d

Option 4: Kubernetes with Helm

For Kubernetes deployments, install directly from the OCI registry.

With ClusterIP + port-forward (development/testing):

helm install databasus oci://ghcr.io/databasus/charts/databasus \
  -n databasus --create-namespace

kubectl port-forward svc/databasus-service 4005:4005 -n databasus
# Access at http://localhost:4005

With LoadBalancer (cloud environments):

helm install databasus oci://ghcr.io/databasus/charts/databasus \
  -n databasus --create-namespace \
  --set service.type=LoadBalancer

kubectl get svc databasus-service -n databasus
# Access at http://<EXTERNAL-IP>:4005

With Ingress (domain-based access):

helm install databasus oci://ghcr.io/databasus/charts/databasus \
  -n databasus --create-namespace \
  --set ingress.enabled=true \
  --set ingress.hosts[0].host=backup.example.com

For more options (NodePort, TLS, HTTPRoute for Gateway API), see the Helm chart README.

🚀 Usage

1. Access the dashboard: Navigate to http://localhost:4005
2. Add your first database for backup: Click "New Database" and follow the setup wizard
3. Configure schedule: Choose from hourly, daily, weekly, monthly or cron intervals
4. Set database connection: Enter your database credentials and connection details
5. Choose storage: Select where to store your backups (local, S3, Google Drive, etc.)
6. Configure retention policy: Choose time period, count or GFS to control how long backups are kept
7. Add notifications (optional): Configure email, Telegram, Slack, or webhook notifications
8. Save and start: Databasus will validate settings and begin the backup schedule

🔑 Resetting password (docs)

If you need to reset the password, you can use the built-in password reset command:

docker exec -it databasus ./main --new-password="YourNewSecurePassword123" --email="admin"

Replace admin with the actual email address of the user whose password you want to reset.

💾 Backuping Databasus itself

After installation, it is also recommended to backup your Databasus itself or, at least, to copy secret key used for encryption (30 seconds is needed). So you are able to restore from your encrypted backups if you lose access to the server with Databasus or it is corrupted.

🛡️ Security & reliability engineering

Databasus works with sensitive data, so preventing vulnerabilities, unauthorised access and data leaks is a primary concern. We invest in this on both sides of the system: in the code itself (permission checks, encryption, careful handling of secrets) and in the infrastructure around it (dependency analysis, CVE response, DevSecOps best practices). The pipeline below runs automatically on every commit and PR. No single layer is enough on its own, but together they reduce the chance of vulnerable code, unsafe dependencies, broken images, or non-restorable backups reaching a release.

For static analysis we combine several independent passes. CodeQL scans the full codebase for security issues. CodeRabbit reviews every PR and runs gitleaks for secret scanning and semgrep for security rules inline. Dockerfiles and CI workflows get extra rules of their own (pinned action references, least-privilege permissions, suspicious base images), so insecure patterns are flagged before they ever merge. On top of these per-PR checks, Codex Security from OpenAI runs regular, deeper audits of the whole codebase. It's a separate program that catches architectural and cross-cutting issues narrow PR-time scans can miss.

On the dependency side, Dependabot watches all of our dependencies against the GitHub Advisory Database and surfaces CVEs within minutes of publication. Updates run through a cooldown so newly-published versions get a chance to mature before we adopt them. This is a deliberate defence against compromised-package incidents like supply-chain attack. The Dependency Review Action blocks any PR that introduces a new HIGH or CRITICAL CVE outright.

Container images are scanned with Trivy on every build. A separate Trivy pass on the Dockerfile catches misconfigurations before they make it into an image. All GitHub Actions are pinned to full commit SHAs rather than floating tags like @v4 or @main, which have been an active attack vector in 2025. Workflows default to least-privilege permissions and only elevate per-job when genuinely needed.

Critical paths are covered by both unit and integration tests, run against real database containers for every supported engine and major version. Restore is the path that matters most for a backup tool, so we test it explicitly: every PR runs full backup-then-restore cycles against those same real containers, verifying that backups can actually be restored end-to-end, not just written successfully. The rest of the CI/CD pipeline runs lint, type-check, the full test suite, image smoke tests and multi-architecture builds on every PR. A release only ships if all of it passes.

Found a vulnerability? Report it via the GitHub Security tab. See SECURITY.md. Security reports are the highest-priority work queue. For runtime application security (AES-256-GCM at rest, zero-trust storage, encrypted secrets, read-only DB user by default) see Enterprise-grade security in the Features section above.
