+
+> **Automated Docker backup system for PostgreSQL databases and application configurations with Duplicati integration**
+
+BackupBot is a comprehensive backup solution that automatically discovers and backs up PostgreSQL containers, creates btrfs snapshots of your application data, and provides a web-based configuration interface. Built on top of LinuxServer.io's Duplicati image, it combines database backups with flexible cloud storage options.
+
+---
+
+## ✨ Features
+
+- 🔍 **Auto-Discovery**: Automatically detects PostgreSQL containers by image patterns
+- 📊 **Multi-Database Support**: Backs up all databases within each PostgreSQL container using `pg_dumpall`
+- 📸 **Filesystem Snapshots**: Creates read-only btrfs snapshots of application data
+- 🔄 **Automated Scheduling**: Configurable backup times with retry logic
+- 🌐 **Web Interface**: Simple configuration UI accessible on port 8080
+- 🔔 **Gotify Integration**: Optional push notifications for backup failures
+- 🗄️ **Duplicati Integration**: Full access to Duplicati for cloud backup destinations
+- 🧹 **Retention Management**: Automatic cleanup of old backups based on retention policy
+- 🐳 **Docker-Native**: Designed to run in containerized environments
+
+---
+
+## 🚀 Quick Start
+
+### Prerequisites
+
+- Docker Engine 20.10+
+- Docker Compose 2.0+
+- Btrfs filesystem for snapshot functionality (optional but recommended)
+- Running PostgreSQL containers you want to back up
+
+### Installation
+
+1. **Clone the repository:**
+   ```bash
+   git clone https://gitea.calahilstudios.com/owner/backupbot.git
+   cd backupbot
+   ```
+
+2. **Create environment file:**
+   ```bash
+   cp .env.example .env
+   # Edit .env with your settings
+   nano .env
+   ```
+
+3. **Start the container:**
+   ```bash
+   docker-compose up -d
+   ```
+
+4. **Access the interfaces:**
+   - BackupBot Config: http://localhost:8201
+   - Duplicati Web UI: http://localhost:8200
+
+---
+
+## 📋 Configuration
+
+### Environment Variables
+
+Create a `.env` file in the project root:
+
+```env
+# Duplicati encryption key (required)
+KEY=your_encryption_key_here
+
+# Duplicati web password (required)
+PASSWORD=your_secure_password
+
+# User/Group IDs (optional)
+PUID=1000
+PGID=1000
+
+# Timezone (optional)
+TZ=America/Los_Angeles
+```
+
+### BackupBot Configuration
+
+BackupBot settings are managed through the web interface at `http://localhost:8201` or via the config file at `/config/backupbot.conf`:
+
+```bash
+TZ=America/Los_Angeles
+BACKUP_DIR=/backups/postgres
+LOG_FILE=/config/log/pgbackup.log
+MAX_RETRIES=3
+GOTIFY_URL=http://gotify.example.com
+GOTIFY_TOKEN=your_gotify_token_here
+BACKUP_HOUR=03
+BACKUP_MINUTE=00
+RETENTION_DAYS=7
+```
+
+### Supported PostgreSQL Images
+
+BackupBot automatically detects containers running these images:
+
+- `postgres:17.0-alpine`
+- `postgres:17`
+- `postgres:14.0-alpine`
+- `postgres` (any version)
+- `ghcr.io/immich-app/postgres:*`
+
+Additional patterns can be added by modifying the `KNOWN_IMAGES` list in `backup.sh`.
+
+---
+
+## 🗂️ Volume Mappings
+
+```yaml
+volumes:
+  # Duplicati configuration
+  - /srv/appdata/duplicati/config:/config
+  
+  # Backup storage (where dumps are stored)
+  - /srv/backups:/backups:rshared
+  
+  # Docker socket (for container discovery)
+  - /var/run/docker.sock:/var/run/docker.sock:ro
+  
+  # Source data for snapshots (optional)
+  - /srv/appdata:/source/appdata:ro
+```
+
+---
+
+## 🔧 Usage
+
+### Manual Backup
+
+Trigger a backup manually:
+
+```bash
+docker exec backupbot /usr/local/bin/backup.sh
+```
+
+### View Logs
+
+Monitor backup operations:
+
+```bash
+docker logs -f backupbot
+```
+
+### Check Backup Files
+
+Backups are organized by container name:
+
+```bash
+ls -lh /srv/backups/postgres_dumps/
+```
+
+Example structure:
+```
+/srv/backups/
+├── postgres_dumps/
+│   ├── myapp_db/
+│   │   ├── 2024-10-23_03-00-00.sql
+│   │   └── 2024-10-24_03-00-00.sql
+│   └── another_db/
+│       └── 2024-10-23_03-00-00.sql
+└── snapshots/
+    ├── hostname-2024-10-23/
+    └── hostname-2024-10-24/
+```
+
+---
+
+## 🎯 How It Works
+
+1. **Discovery Phase**: BackupBot scans running Docker containers and identifies PostgreSQL instances
+2. **Extraction**: For each database, credentials are extracted from environment variables
+3. **Backup**: `pg_dumpall` creates a complete SQL dump of all databases
+4. **Snapshot**: A read-only btrfs snapshot is created of `/srv/appdata`
+5. **Retention**: Old backups exceeding the retention period are automatically deleted
+6. **Notification**: On failure after retries, Gotify notifications are sent (if configured)
+
+---
+
+## 🔐 Security Notes
+
+- **Privileged Mode**: Required for btrfs snapshot functionality
+- **Docker Socket**: Read-only access needed for container discovery
+- **Credentials**: Database passwords are extracted from container environment variables
+- **Network**: BackupBot runs in bridge mode by default
+
+### Best Practices
+
+- Use strong encryption keys for Duplicati
+- Restrict access to the web interfaces using a reverse proxy with authentication
+- Regularly test backup restoration procedures
+- Store encryption keys securely outside the container
+
+---
+
+## 🛠️ Development
+
+### Building from Source
+
+```bash
+docker build -t backupbot:latest .
+```
+
+### CI/CD Pipeline
+
+BackupBot uses Gitea Actions for automated builds:
+
+- **Trigger**: Push to `main` or `develop` branches
+- **Registry**: `gitea.calahilstudios.com`
+- **Tags**: `develop` and commit SHA
+
+---
+
+## 📊 Monitoring
+
+### Web Interfaces
+
+- **BackupBot Config**: `http://localhost:8201`
+  - Configure backup schedules
+  - Set retention policies
+  - Manage Gotify notifications
+
+- **Duplicati**: `http://localhost:8200`
+  - Configure cloud storage destinations
+  - Schedule remote backups
+  - Restore from backups
+
+### Log Levels
+
+Set via `BACKUPBOT_WEB_LOGGING` environment variable:
+- `DEBUG`: Verbose logging with exception traces
+- `INFO`: Standard operational logs (default)
+- `WARN`: Warnings and errors only
