chore: bump version to 1.0.99 (backend + frontend)

- Display email address instead of username in migration output
- Use environment variables for admin email configuration
- Update deployment guide with clear admin setup instructions
- Add note that login requires email address, not username
- Fix GitHub URL to correct repository
- Remove obsolete version field from docker-compose.yml

-# Security Scan Report - Wedding Photo Sharing Application
-**Date**: July 13, 2025  
-**Scanner**: Claude Security Audit with --security --validate flags  
-**Overall Risk Level**: MEDIUM-HIGH  
-
-## Executive Summary
-
-The wedding photo sharing application demonstrates strong security fundamentals with comprehensive input validation, proper authentication mechanisms, and good file security practices. However, several critical issues require immediate attention, particularly around hardcoded secrets, token storage, and Content Security Policy configuration.
-
-### Security Score: 6.5/10
-
-**Strengths**: Excellent input validation, parameterized queries, file security, rate limiting  
-**Critical Issues**: Hardcoded JWT secrets, localStorage token storage, weak CSP, console logging in production
-
----
-
-## 🔴 CRITICAL FINDINGS (Immediate Action Required)
-
-### 1. Hardcoded JWT Secret in Development
-- **Location**: Backend `.env` file
-- **Risk**: Token forgery, authentication bypass
-- **Impact**: Complete authentication compromise
-- **Remediation**: 
-  ```bash
-  # Generate secure secret
-  openssl rand -base64 32
-  # Never commit to repository
-  echo ".env" >> .gitignore
-  ```
-
-### 2. Gallery Tokens in localStorage
-- **Location**: Frontend `api.ts` and auth contexts
-- **Risk**: XSS token theft
-- **Impact**: Gallery access compromise
-- **Remediation**: Move to httpOnly cookies:
-  ```typescript
-  Cookies.set(`gallery_token_${slug}`, token, {
-    httpOnly: true,
-    secure: true,
-    sameSite: 'strict'
-  });
-  ```
-
-### 3. Weak Content Security Policy
-- **Location**: Frontend `nginx.conf`
-- **Risk**: XSS, code injection
-- **Current**: `unsafe-inline` and `unsafe-eval` allowed
-- **Remediation**: Implement strict CSP (see detailed recommendations below)
-
----
-
-## 🟠 HIGH SEVERITY FINDINGS
-
-### 1. Console Logging in Production
-- **Locations**: 61 instances across frontend
-- **Risk**: Information disclosure
-- **Impact**: Leaking sensitive data, debugging info
-- **Remediation**: Implement environment-aware logging
-
-### 2. Token Revocation Vulnerability
-- **Location**: Backend `tokenRevocation.js`
-- **Risk**: Token manipulation
-- **Impact**: Bypass revocation checks
-- **Remediation**: Verify token signature before decoding
-
-### 3. Source Maps in Production
-- **Location**: Frontend build configuration
-- **Risk**: Source code exposure
-- **Impact**: Reveals application structure
-- **Remediation**: Disable in production builds
-
-### 4. Missing Security Headers
-- **Location**: nginx configuration
-- **Missing**: HSTS, Permissions-Policy
-- **Impact**: Various client-side attacks
-- **Remediation**: Add comprehensive security headers
-
----
-
-## 🟡 MEDIUM SEVERITY FINDINGS
-
-### 1. Rate Limiting Bypass Potential
-- **Location**: Backend rate limiter
-- **Risk**: DoS attacks
-- **Current**: JWT validation in rate limiter
-- **Remediation**: Use IP-based limiting only
-
-### 2. Incomplete SQL Injection Protection
-- **Location**: Complex dashboard queries
-- **Risk**: Potential injection in edge cases
-- **Current**: Mostly parameterized
-- **Remediation**: Use query builder exclusively
-
-### 3. Session Management
-- **Issue**: No gallery token invalidation on password change
-- **Risk**: Persistent access after compromise
-- **Remediation**: Implement token revocation
-
-### 4. Path Traversal in Gallery Slugs
-- **Location**: Frontend gallery routes
-- **Risk**: Directory traversal attempts
-- **Remediation**: Validate and sanitize slugs
-
----
-
-## 🟢 LOW SEVERITY FINDINGS
-
-### 1. Verbose Error Messages
-- **Location**: Multiple API endpoints
-- **Risk**: Information disclosure
-- **Remediation**: Generic client errors, detailed server logs
-
-### 2. Weak Gallery Passwords
-- **Current**: zxcvbn score 2/4 allowed
-- **Risk**: Brute force attacks
-- **Remediation**: Increase to score 3/4
-
-### 3. Missing File Size Validation
-- **Location**: Frontend upload components
-- **Risk**: DoS via large uploads
-- **Remediation**: Add client-side size checks
-
----
-

+## Troubleshooting Guidelines
+
+### Before ANY Production Troubleshooting:
+1. **ALWAYS request specific details**:
+   - Production server URL/IP
+   - Current error messages/logs
+   - Recent changes or deployments
+   - Affected users/galleries
+   - Time of issue occurrence
+
+2. **Thorough Analysis Required**:
+   - Use detailed thinking/analysis for EVERY troubleshooting task
+   - Review all related code before suggesting changes
+   - Consider all potential side effects
+   - Never make assumptions about production environment
+
+3. **Safe Troubleshooting Steps**:
+   - First, reproduce issue in local/dev environment
+   - Analyze logs without modifying production
+   - Create detailed action plan before any changes
+   - Always have rollback strategy ready
+   - Document every step taken
+
+### Common Issues & Safe Approaches:
+- **Email not sending**: Check email_queue table, SMTP settings, service status
+- **Photos not loading**: Verify file permissions, storage paths, nginx config
+- **Gallery access issues**: Check JWT tokens, expiration dates, access_logs
+- **Performance problems**: Analyze with monitoring tools first, never experiment
+
+### Data Safety Rules:
+- NEVER delete or modify production data without explicit backup confirmation
+- ALWAYS verify backups exist before any data operations
+- NO direct database modifications without transaction safety
+- Log all actions for audit trail

+## Backup Service
+
+### Overview
+The backup service provides automated, scheduled backups of all photo data with checksum-based change detection to minimize transfer overhead.
+
+### Features
+- **Multiple Destinations**: Local directory, remote server (rsync), S3-compatible storage
+- **Change Detection**: SHA256 checksums track file changes, only modified files are backed up
+- **Scheduled Execution**: Configurable cron-based scheduling (default: 2 AM daily)
+- **Email Notifications**: Alerts on backup failure, optional success notifications
+- **Retention Management**: Automatic cleanup of old backup runs based on retention policy
+- **Progress Tracking**: Database storage of backup history, file states, and statistics
+
+### Configuration
+Backup settings are stored in `app_settings` table with `backup_` prefix:
+- `backup_enabled`: Enable/disable the service
+- `backup_schedule`: Cron expression (e.g., '0 2 * * *')
+- `backup_destination_type`: 'local', 'rsync', or 's3'
+- `backup_retention_days`: How long to keep backup history
+- `backup_include_archived`: Whether to backup archived events
+- `backup_exclude_patterns`: File patterns to exclude
+
+### API Endpoints
+- `GET /api/admin/backup/config` - Get current configuration
+- `PUT /api/admin/backup/config` - Update configuration
+- `GET /api/admin/backup/status` - Get backup status and history
+- `POST /api/admin/backup/run` - Trigger manual backup
+- `POST /api/admin/backup/test-connection` - Test destination connectivity
+
+### Testing
+Run backup service test: `npm run test-backup`
+
+### Database Tables
+- `backup_runs`: Tracks each backup execution with statistics
+- `backup_file_states`: Stores file checksums for change detection
+
 ## Success Metrics (from PRD)
 - Time to generate gallery: <2 minutes
 - Guest satisfaction: >90%
 - System uptime: 99.9%
 - Email delivery rate: >98%
-- Successful archiving: 100%
+- Successful archiving: 100%
+
+## Documentation & Development Practices
+
+### Documentation Guidelines:
+- **NEVER create new documentation files for simple tasks**
+- **ALWAYS update existing documentation (like this CLAUDE.md)**
+- Only create new .md files when explicitly requested
+- Avoid creating temporary scripts for one-off tasks
+
+### Development Best Practices:
+- Test all changes thoroughly in local environment first
+- Use version control for all changes
+- Keep commits atomic and well-described
+- Review impact on all integrated services
+- Consider backward compatibility
+- Update tests when changing functionality
+
+### Production Deployment Checklist:
+- [ ] All tests passing locally
+- [ ] Linting and type checks pass
+- [ ] Database migrations tested with rollback plan
+- [ ] Environment variables documented
+- [ ] Backup strategy confirmed
+- [ ] Monitoring alerts configured
+- [ ] Rollback procedure documented
+- [ ] Stakeholders notified of maintenance window

-# 🚀 PicPeak Deployment Guide
-
-This guide will help you deploy PicPeak in production. The entire process takes about 10-15 minutes.
-
-## 📋 Prerequisites
-
-- A server with Docker and Docker Compose installed
-- A domain name (for SSL certificates)
-- SMTP credentials for sending emails
-- Basic command line knowledge
-
-## 🏃 Quick Deploy (Recommended)
-
-### 1. Clone and Configure
-
-```bash
-# Clone the repository
-git clone https://github.com/the-luap/picpeak.git
-cd picpeak
-
-# Copy environment template
-cp .env.production.example .env
-
-# Generate a secure JWT secret
-echo "JWT_SECRET=$(openssl rand -base64 32)" >> .env
-
-# Edit configuration
-nano .env
-```
-
-### 2. Required Environment Variables
-
-Edit your `.env` file with these essential settings:
-
-```env
-# Application URLs
-FRONTEND_URL=https://your-domain.com
-BACKEND_URL=https://your-domain.com
-
-# Email Configuration (Required for notifications)
-SMTP_HOST=smtp.gmail.com
-SMTP_PORT=587
-SMTP_USER=your-email@gmail.com
-SMTP_PASS=your-app-password
-SMTP_FROM=your-email@gmail.com
-
-# Admin Configuration
-ADMIN_EMAIL=admin@your-domain.com
-ADMIN_PASSWORD=your-secure-password
-
-# Database (PostgreSQL for production)
-DATABASE_CLIENT=pg
-DB_HOST=postgres
-DB_NAME=picpeak
-DB_USER=picpeak
-DB_PASSWORD=secure-db-password
-```
-
-### 3. Deploy with Docker Compose
-
-```bash
-# Start all services
-docker-compose -f docker-compose.prod.yml up -d
-
-# Check logs
-docker-compose logs -f
-
-# Access your site at https://your-domain.com
-```
-
-## 🔧 Configuration Options
-
-### Storage Settings
-
-```env
-# Storage paths (default: ./storage)
-STORAGE_PATH=./storage
-ARCHIVE_PATH=./storage/archives
-
-# Gallery expiration (days)
-DEFAULT_EXPIRATION_DAYS=30
-WARNING_DAYS_BEFORE_EXPIRY=7
-```
-
-### Security Settings
-
-```env

-
-## 🔒 SSL/TLS Setup
-
-The production Docker Compose includes automatic SSL via Let's Encrypt:
-
-1. **Ensure your domain points to your server**
-2. **Update nginx configuration**:
-   ```bash
-   nano nginx/nginx.conf
-   # Replace your-domain.com with your actual domain
-   ```
-3. **Start services** - Certbot will automatically obtain certificates
-
-## 📁 Directory Structure
-
-After deployment, your directory structure will be:
-
-```

-- Verify file watcher is running: `docker-compose logs backend | grep watcher`
-
-**Email not sending:**
-- Test SMTP settings: Admin Panel → Settings → Email → Send Test
-- Check email queue: Admin Panel → System → Email Queue
-
-**Can't access admin panel:**
-- Default login: Use email/password from `.env`
-- Reset password: `docker exec picpeak-backend npm run reset-admin`
-
-### Health Check
-
-```bash
-# Check service status
-docker-compose ps
-
-# Test backend API
-curl https://your-domain.com/api/health
-
-# Check disk space
-df -h storage/
-```
-

+
+## Prerequisites
+
+- Docker and Docker Compose installed
+- Domain name (for production)
+- SMTP server credentials for emails
+- At least 2GB RAM and 20GB storage
+
+## 🚀 Quick Start
+
+1. **Clone the repository**
+   ```bash
+   git clone https://github.com/the-luap/picpeak.git
+   cd picpeak
+   ```
+
+2. **Set up environment**
+   ```bash
+   cp .env.example .env
+   nano .env  # Edit with your values
+   ```
+
+3. **Create required directories**
+   ```bash
+   mkdir -p events/active events/archived data logs backup storage
+   chmod -R 755 events data logs backup storage
+   ```
+
+4. **Deploy**
+   ```bash
+   docker compose up -d
+   ```
+
+5. **Check logs**
+   ```bash
+   docker compose logs -f
+   ```
+
+## 🔧 Configuration
+
+### Essential Environment Variables
+
+Generate secure values:
+```bash
+# JWT Secret
+openssl rand -base64 64
+
+# Database Password
+openssl rand -base64 32
+
+# Redis Password
+openssl rand -base64 32
+```
+
+Update `.env` with:
+- `JWT_SECRET` - Authentication secret
+- `DB_PASSWORD` - PostgreSQL password
+- `REDIS_PASSWORD` - Redis password
+- `SMTP_*` - Email configuration
+- `FRONTEND_URL` - Your domain URL
+- `ADMIN_URL` - Backend admin URL
+- `VITE_API_URL` - API URL for frontend
+
+### Email Configuration Examples
+
+#### Gmail
+```env
+SMTP_HOST=smtp.gmail.com
+SMTP_PORT=587
+SMTP_SECURE=false
+SMTP_USER=your-email@gmail.com
+SMTP_PASS=your-app-specific-password
+```
+
+#### SendGrid
+```env
+SMTP_HOST=smtp.sendgrid.net
+SMTP_PORT=587
+SMTP_SECURE=false
+SMTP_USER=apikey
+SMTP_PASS=your-sendgrid-api-key
+```
+
+## 📦 Deployment
+
+### Build and Start Services
+
+```bash
+# Build images
+docker compose build
+
+# Start all services
+docker compose up -d
+
+# View running containers
+docker compose ps
+```
+
+### Access Points
+
+By default, services are exposed on:
+- Frontend: http://localhost:3000
+- Backend/API: http://localhost:3001
+- PostgreSQL: localhost:5432 (if needed)
+- Redis: localhost:6379 (if needed)
+
+### Initial Admin Setup
+
+When deploying for the first time, an admin account is automatically created with a secure random password. You need to retrieve this password to access the admin panel.
+
+#### Finding the Admin Password
+
+**Option 1: Check the backend logs** (recommended)
+```bash
+# View the initial setup logs
+docker compose logs backend | grep -A 10 "Admin user created"
+```
+
+You should see output like:
+```
+========================================
+✅ Admin user created successfully!
+========================================
+Email: admin@example.com
+Password: BraveTiger6231!
+
+⚠️  IMPORTANT:
+1. Save these credentials securely
+2. Please change the password after first login
+========================================
+```
+
+**Note**: You login with the **email address**, not a username!
+
+**Option 2: Check the saved credentials file**
+```bash
+# The password is saved in the backend container
+docker exec picpeak-backend cat data/ADMIN_CREDENTIALS.txt
+```
+
+**Option 3: Use the helper script**
+```bash
+# Show current admin username and email (password is hidden)
+docker exec picpeak-backend node scripts/show-admin-credentials.js
+
+# Reset the admin password to a new random password
+docker exec picpeak-backend node scripts/show-admin-credentials.js --reset
+```
+
+#### Important Notes
+
+- **Login requires the email address**, not username
+- The admin password is only shown once during initial setup
+- If you lose the password, use the `--reset` option to generate a new one
+- You must change the password on first login (enforced by the system)
+- Password requirements: minimum 12 characters, mixed case, numbers, and special characters
+
+#### Configuring Admin Email
+
+By default, the admin email is `admin@example.com`. To use a different email address, set it in your `.env` file before first deployment:
+
+```env
+# .env
+ADMIN_EMAIL=your-email@yourdomain.com
+```
+
+**Note**: This only works on first deployment. To change the admin email after deployment, you'll need to update it in the database or create a new admin user through the admin panel.
+
+## 🔒 Reverse Proxy Setup
+
+For production deployments, you should use a reverse proxy for SSL/HTTPS. The application exposes ports directly, allowing you to use any reverse proxy solution.
+
+### Option 1: Nginx
+
+Install nginx and create `/etc/nginx/sites-available/picpeak`:
+
+```nginx
+server {
+    listen 80;
+    server_name your-domain.com;
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name your-domain.com;
+
+    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
+
+    # Frontend
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+
+    # Backend API
+    location /api {
+        proxy_pass http://localhost:3001;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+
+    # Protected photos and uploads
+    location ~ ^/(photos|thumbnails|uploads) {
+        proxy_pass http://localhost:3001;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    }
+
+    # Admin routes
+    location /admin {
+        proxy_pass http://localhost:3001;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+Enable the site:
+```bash
+sudo ln -s /etc/nginx/sites-available/picpeak /etc/nginx/sites-enabled/
+sudo nginx -t
+sudo systemctl reload nginx
+```
+
+### Option 2: Traefik
+
+Add labels to `docker-compose.override.yml`:
+
+```yaml
+version: '3.8'
+
+services:
+  frontend:
+    labels:
+      - "traefik.enable=true"
+      - "traefik.http.routers.picpeak.rule=Host(`your-domain.com`)"
+      - "traefik.http.routers.picpeak.entrypoints=websecure"
+      - "traefik.http.routers.picpeak.tls.certresolver=letsencrypt"
+      - "traefik.http.services.picpeak.loadbalancer.server.port=80"
+
+  backend:
+    labels:
+      - "traefik.enable=true"
+      - "traefik.http.routers.picpeak-api.rule=Host(`your-domain.com`) && PathPrefix(`/api`)"
+      - "traefik.http.routers.picpeak-api.entrypoints=websecure"
+      - "traefik.http.routers.picpeak-api.tls.certresolver=letsencrypt"
+      - "traefik.http.services.picpeak-api.loadbalancer.server.port=3001"
+```
+
+### Option 3: Caddy
+
+Create a `Caddyfile`:
+
+```caddyfile
+your-domain.com {
+    # Frontend
+    handle /* {
+        reverse_proxy localhost:3000
+    }
+
+    # Backend API and admin
+    handle /api/* {
+        reverse_proxy localhost:3001
+    }
+    
+    handle /admin/* {
+        reverse_proxy localhost:3001
+    }
+
+    # Protected resources
+    handle /photos/* {
+        reverse_proxy localhost:3001
+    }
+
+    handle /thumbnails/* {
+        reverse_proxy localhost:3001
+    }
+
+    handle /uploads/* {
+        reverse_proxy localhost:3001
+    }
+}
+```
+
+### SSL Certificates
+
+For any reverse proxy, you can use Let's Encrypt:
+
+```bash
+# With Certbot
+sudo certbot certonly --webroot -w /var/www/certbot -d your-domain.com
+
+# Or use your reverse proxy's built-in ACME support
+```
+
+## 🔧 Maintenance
+
+### Viewing Logs
+
+```bash
+# All services
+docker compose logs -f
+
+# Specific service
+docker compose logs -f backend
+docker compose logs -f frontend
+```
+
+### Backup
+
+#### Manual Backup
+```bash
+# Database backup
+docker exec picpeak-postgres pg_dump -U picpeak picpeak_prod > backup/db_$(date +%Y%m%d_%H%M%S).sql
+
+# Files backup
+tar -czf backup/photos_$(date +%Y%m%d_%H%M%S).tar.gz events/
+```
+
+#### Automated Backup
+The application includes a built-in backup service. Configure it in the admin panel:
+1. Login to admin panel
+2. Go to Settings → Backup
+3. Configure destination and schedule
+4. Enable backup service
+
+### Updates
+
+```bash
+# Pull latest changes
+git pull
+
+# Rebuild and restart
+docker compose down
+docker compose build
+docker compose up -d
+```
+
+### Database Migrations
+
+Migrations run automatically on startup, but you can run them manually:
+
+```bash
+docker exec picpeak-backend npm run migrate
+```
+
+## 🚨 Troubleshooting
+
+### Common Issues
+
+#### Port Already in Use
+```bash
+# Check what's using the port
+sudo lsof -i :3000
+sudo lsof -i :3001
+
+# Change ports in .env
+FRONTEND_PORT=3002
+BACKEND_PORT=3003
+```
+
+#### Permission Errors
+```bash
+# Fix ownership
+sudo chown -R 1000:1000 events data logs backup storage
+chmod -R 755 events data logs backup storage
+```
+
+#### Database Connection Issues
+```bash
+# Check if database is running
+docker compose ps
+docker compose logs postgres
+
+# Test connection
+docker exec picpeak-postgres pg_isready
+```
+
+#### Email Not Sending
+- Verify SMTP settings in .env
+- Check email queue: `docker exec picpeak-backend psql -U picpeak -d picpeak_prod -c "SELECT * FROM email_queue ORDER BY created_at DESC LIMIT 10;"`
+- For Gmail, use app-specific password
+- Check logs: `docker compose logs backend | grep email`
+
+### Health Checks
+
+```bash
+# Backend health
+curl http://localhost:3001/api/health
+
+# Frontend health
+curl http://localhost:3000
+
+# Database health
+docker exec picpeak-postgres pg_isready
+```
+
+### Useful Commands
+
+```bash
+# Enter backend container
+docker exec -it picpeak-backend sh
+
+# Enter database
+docker exec -it picpeak-postgres psql -U picpeak picpeak_prod
+
+# Reset admin password
+docker exec picpeak-backend node scripts/show-admin-credentials.js --reset
+
+# Check disk usage
+df -h
+du -sh events/ storage/ backup/
+
+# View running processes
+docker compose top
+```
+
+## Security Recommendations
+
+1. **Use HTTPS**: Always use a reverse proxy with SSL in production
+2. **Firewall**: Only expose necessary ports (80, 443)
+3. **Secure passwords**: Use strong, unique passwords for all services
+4. **Regular updates**: Keep Docker images and system packages updated
+5. **Backup strategy**: Set up automated backups and test restoration
+6. **Monitor logs**: Regularly check logs for suspicious activity
+7. **Rate limiting**: The app includes built-in rate limiting, configure as needed
+
+## Support
+
+For issues and questions:
+- Check logs first: `docker compose logs`
+- Review documentation in the repository
+- Check existing issues on GitHub
+- Create a new issue with:
+  - Error messages
+  - Log output
+  - Environment details (without secrets)
+  - Steps to reproduce

-# Production Deployment Guide
-
-This guide explains how to deploy PicPeak in production behind a reverse proxy like Traefik.
-
-## Environment Configuration
-
-### Frontend Configuration
-
-For production deployment behind a reverse proxy (Traefik, Nginx, etc.), the frontend should use relative URLs to automatically inherit the protocol (HTTPS) and domain.
-
-1. Copy the production environment template:
-   ```bash
-   cp frontend/.env.production.example frontend/.env.production
-   ```
-
-2. Set the API URL to use relative path:
-   ```env
-   # frontend/.env.production
-   VITE_API_URL=/api
-   ```
-
-   This ensures all API calls will use the same domain and protocol as the frontend.
-
-### Backend Configuration
-
-Ensure your backend `.env` file has the correct URLs:
-```env
-# backend/.env
-FRONTEND_URL=https://yourdomain.com
-ADMIN_URL=https://yourdomain.com
-```
-
-## Docker Compose Production
-
-When using Docker Compose in production:
-
-1. Build with production environment:
-   ```bash
-   docker-compose -f docker-compose.prod.yml build --build-arg NODE_ENV=production
-   ```
-
-2. The frontend nginx configuration already includes proper proxy settings for:
-   - `/api` → Backend API
-   - `/photos` → Protected photo access
-   - `/thumbnails` → Thumbnail images
-   - `/uploads` → Public uploads (logos, favicons)
-
-## Traefik Configuration
-
-Example Traefik labels for docker-compose:
-
-```yaml
-services:
-  frontend:
-    labels:
-      - "traefik.enable=true"
-      - "traefik.http.routers.picpeak.rule=Host(`yourdomain.com`)"
-      - "traefik.http.routers.picpeak.entrypoints=websecure"
-      - "traefik.http.routers.picpeak.tls.certresolver=letsencrypt"
-      - "traefik.http.services.picpeak.loadbalancer.server.port=80"
-```
-
-## Important Notes
-
-1. **No Hardcoded URLs**: The application uses environment variables with relative URL fallbacks, making it production-ready.
-
-2. **HTTPS Only**: When `VITE_API_URL=/api`, all requests will use the same protocol as the page (HTTPS in production).
-
-3. **CORS Configuration**: The backend CORS is configured to accept requests from the URLs specified in `FRONTEND_URL` and `ADMIN_URL`.
-
-4. **Static Assets**: All static assets (photos, thumbnails, uploads) are served through the nginx proxy, inheriting authentication headers.
-
-## Verification
-
-After deployment, verify:
-
-1. Check browser console for any localhost URLs (there should be none)
-2. Verify all API calls use HTTPS
-3. Check that images load correctly with authentication
-4. Test favicon and logo display
-
-## Troubleshooting
-
-If you see console errors about localhost:
-
-1. Ensure `VITE_API_URL=/api` in frontend environment
-2. Clear browser cache
-3. Rebuild frontend with production environment:
-   ```bash
-   cd frontend
-   npm run build
-   ```
-
-If images don't load:
-
-1. Check that nginx proxy locations are configured
-2. Verify authentication tokens are being sent
-3. Check backend logs for authentication errors

-# Production Deployment Guide
-
-This guide addresses all known production deployment issues and provides solutions.
-
-## Pre-Deployment Checklist
-
-### 1. Environment Variables
-Create a `.env` file with ALL required variables:
-
-```bash
-# Required
-JWT_SECRET=<generate-with-openssl-rand-base64-32>
-DB_PASSWORD=<strong-password>
-ADMIN_URL=https://yourdomain.com
-FRONTEND_URL=https://yourdomain.com
-
-# Database
-DB_USER=picpeak
-DB_NAME=picpeak
-
-# Email (Optional but recommended)
-SMTP_HOST=smtp.gmail.com
-SMTP_PORT=587
-SMTP_SECURE=false
-SMTP_USER=your-email@gmail.com
-SMTP_PASS=your-app-password
-EMAIL_FROM=noreply@yourdomain.com
-
-# Umami Analytics (Optional)
-UMAMI_URL=https://analytics.yourdomain.com
-UMAMI_WEBSITE_ID=your-website-id
-UMAMI_HASH_SALT=<generate-random-string>
-```
-
-### 2. Generate Secrets
-
-```bash
-# Generate JWT Secret
-openssl rand -base64 32
-
-# Generate Database Password
-openssl rand -base64 24
-
-# Generate Umami Hash Salt
-openssl rand -hex 32
-```
-
-## Deployment Steps
-
-### 1. Initial Setup
-
-```bash
-# Clone repository
-git clone https://github.com/the-luap/wedding-photo-sharing.git
-cd wedding-photo-sharing
-
-# Create required directories
-mkdir -p storage/events/active storage/events/archived storage/thumbnails storage/uploads
-mkdir -p data logs
-mkdir -p certbot/conf certbot/www
-
-# Set permissions (important!)
-chmod -R 755 storage data logs
-```
-
-### 2. Fix Docker Volume Permissions
-
-Create `docker-compose.override.yml` for local volume configuration:
-
-```yaml
-version: '3.8'
-
-services:
-  backend:
-    volumes:
-      - ./storage:/app/storage:delegated
-      - ./data:/app/data:delegated
-      - ./logs:/app/logs:delegated
-    user: "1001:1001"  # nodejs user
-
-  db:
-    volumes:
-      - ./postgres-data:/var/lib/postgresql/data
-```
-
-### 3. Build and Deploy
-
-```bash
-# Build images
-docker-compose -f docker-compose.prod.yml build
-
-# Start services
-docker-compose -f docker-compose.prod.yml up -d
-
-# Check logs
-docker-compose -f docker-compose.prod.yml logs -f backend
-```
-
-### 4. Create Admin User
-
-After deployment, create the first admin user:
-
-```bash
-# Enter backend container
-docker-compose -f docker-compose.prod.yml exec backend sh
-
-# Create admin
-node scripts/create-admin.js \
-  --username admin \
-  --email admin@yourdomain.com \
-  --password <your-secure-password>
-
-# Exit container
-exit
-```
-
-### 5. Configure Email (if using database config)
-
-1. Login to admin panel: https://yourdomain.com/admin
-2. Go to Settings > Email Configuration
-3. Enter SMTP details
-4. Test email sending
-
-## Common Issues and Solutions
-
-### Issue 1: Migration Failures
-
-**Error**: "relation already exists"
-
-**Solution**: The safe migration runner handles this automatically. If issues persist:
-
-```bash
-# Reset migrations tracking
-docker-compose -f docker-compose.prod.yml exec db psql -U picpeak -d picpeak
-
-# In PostgreSQL:
-DROP TABLE IF EXISTS migrations;
-\q
-
-# Re-run migrations
-docker-compose -f docker-compose.prod.yml exec backend npm run migrate:safe
-```
-
-### Issue 2: Permission Denied Errors
-
-**Error**: "EACCES: permission denied"
-
-**Solution**: Fix container permissions:
-
-```bash
-# Stop containers
-docker-compose -f docker-compose.prod.yml down
-
-# Fix permissions on host
-sudo chown -R 1001:1001 storage data logs
-
-# Restart
-docker-compose -f docker-compose.prod.yml up -d
-```
-
-### Issue 3: Database Connection Failed
-
-**Error**: "no pg_hba.conf entry"
-
-**Solution**: Already fixed in docker-compose.prod.yml with:
-- SSL disabled for internal Docker network
-- Proper authentication method (scram-sha-256)
-
-### Issue 4: Frontend Can't Connect to Backend
-
-**Error**: CORS errors or connection refused
-
-**Solution**: Ensure environment variables match:
-- Backend: `FRONTEND_URL` must match your frontend URL
-- Frontend: `VITE_API_URL` must be set during build
-
-### Issue 5: Email Not Sending
-
-**Solution**: Check email configuration:
-
-```bash
-# Check backend logs
-docker-compose -f docker-compose.prod.yml logs backend | grep email
-
-# Verify SMTP settings
-# Gmail users: Use app password, not regular password
-# Enable "Less secure app access" or use OAuth2
-```
-
-## SSL/HTTPS Setup
-
-1. Update `nginx/sites-enabled/default` with your domain
-2. Run certbot:
-
-```bash
-# Initial certificate
-docker-compose -f docker-compose.prod.yml run --rm certbot certonly \
-  --webroot --webroot-path=/var/www/certbot \
-  -d yourdomain.com -d www.yourdomain.com
-
-# Auto-renewal is handled by the certbot container
-```
-
-## Monitoring
-
-### Health Checks
-
-```bash
-# Backend health
-curl http://localhost/api/health
-
-# Database connection
-docker-compose -f docker-compose.prod.yml exec backend \
-  psql -U picpeak -d picpeak -c "SELECT 1"
-```
-
-### Logs
-
-```bash
-# All services
-docker-compose -f docker-compose.prod.yml logs -f
-
-# Specific service
-docker-compose -f docker-compose.prod.yml logs -f backend
-```
-
-## Backup and Restore
-
-### Backup
-
-```bash
-#!/bin/bash
-# backup.sh
-DATE=$(date +%Y%m%d_%H%M%S)
-BACKUP_DIR="./backups/$DATE"
-
-mkdir -p $BACKUP_DIR
-
-# Database
-docker-compose -f docker-compose.prod.yml exec -T db \
-  pg_dump -U picpeak picpeak > $BACKUP_DIR/database.sql
-
-# Files
-tar -czf $BACKUP_DIR/storage.tar.gz storage/
-
-echo "Backup completed: $BACKUP_DIR"
-```
-
-### Restore
-
-```bash
-# Database
-docker-compose -f docker-compose.prod.yml exec -T db \
-  psql -U picpeak picpeak < ./backups/20240713_120000/database.sql
-
-# Files
-tar -xzf ./backups/20240713_120000/storage.tar.gz
-```
-
-## Production Best Practices
-
-1. **Always use named volumes** in production for better data persistence
-2. **Set up monitoring** with Prometheus/Grafana
-3. **Enable backups** with automated scripts
-4. **Use a reverse proxy** (Nginx) for SSL termination
-5. **Implement rate limiting** at the Nginx level
-6. **Regular updates** - Keep Docker images updated
-7. **Log rotation** - Configure log rotation for application logs
-
-## Troubleshooting Commands
-
-```bash
-# Check running containers
-docker-compose -f docker-compose.prod.yml ps
-
-# Restart a service
-docker-compose -f docker-compose.prod.yml restart backend
-
-# View real-time logs
-docker-compose -f docker-compose.prod.yml logs -f --tail=100
-
-# Execute commands in container
-docker-compose -f docker-compose.prod.yml exec backend sh
-
-# Database shell
-docker-compose -f docker-compose.prod.yml exec db psql -U picpeak
-
-# Clean restart
-docker-compose -f docker-compose.prod.yml down
-docker-compose -f docker-compose.prod.yml up -d
-```

+# Enhanced Backup System Test Suite
+
+This directory contains comprehensive tests for the enhanced backup system with S3 support.
+
+## Test Structure
+
+### Unit Tests
+- `services/backupService.enhanced.test.js` - Unit tests for the enhanced backup service
+  - Configuration management
+  - S3 backup functionality
+  - Manifest generation
+  - Error handling and recovery
+  - Backward compatibility (local and rsync)
+  - Service lifecycle management
+
+### Integration Tests
+- `integration/backup-s3.test.js` - Integration tests for S3 backups
+  - Real S3/MinIO connection tests
+  - Full backup process with actual files
+  - Incremental backup verification
+  - Manifest storage and retrieval
+  - Error recovery scenarios
+
+### Manual Integration Test Script
+- `../scripts/test-backup-integration.js` - Comprehensive manual testing script
+  - Can test against MinIO, AWS S3, or any S3-compatible service
+  - Tests all backup types (S3, local, rsync)
+  - Performance testing with large files
+  - Detailed progress reporting
+
+## Running Tests
+
+### Prerequisites
+
+1. **For Unit Tests**: No special setup required, all dependencies are mocked.
+
+2. **For Integration Tests**: Requires a running S3-compatible service (MinIO recommended)
+   ```bash
+   # Start MinIO using Docker
+   docker run -d \
+     -p 9000:9000 \
+     -p 9001:9001 \
+     --name minio-test \
+     -e MINIO_ROOT_USER=minioadmin \
+     -e MINIO_ROOT_PASSWORD=minioadmin \
+     minio/minio server /data --console-address ":9001"
+   ```
+
+3. **Environment Variables** (for integration tests):
+   ```bash
+   # Optional - defaults work with local MinIO
+   export TEST_S3_ENDPOINT=http://localhost:9000
+   export TEST_S3_ACCESS_KEY=minioadmin
+   export TEST_S3_SECRET_KEY=minioadmin
+   
+   # Skip S3 tests if no S3 service available
+   export SKIP_S3_TESTS=true
+   ```
+
+### Running Unit Tests
+
+```bash
+# Run all backup service tests
+npm test -- __tests__/services/backupService.enhanced.test.js
+
+# Run specific test suite
+npm test -- __tests__/services/backupService.enhanced.test.js -t "S3 Backup Functionality"
+
+# Run with coverage
+npm test -- --coverage __tests__/services/backupService.enhanced.test.js
+```
+
+### Running Integration Tests
+
+```bash
+# Ensure MinIO is running first!
+
+# Run S3 integration tests
+npm test -- __tests__/integration/backup-s3.test.js
+
+# Run with verbose output
+npm test -- __tests__/integration/backup-s3.test.js --verbose
+
+# Skip S3 tests if needed
+SKIP_S3_TESTS=true npm test -- __tests__/integration/backup-s3.test.js
+```
+
+### Running Manual Integration Tests
+
+```bash
+# Test with local MinIO (default)
+node scripts/test-backup-integration.js
+
+# Test with AWS S3
+node scripts/test-backup-integration.js \
+  --endpoint https://s3.amazonaws.com \
+  --access-key YOUR_ACCESS_KEY \
+  --secret-key YOUR_SECRET_KEY \
+  --bucket your-test-bucket
+
+# Test local backup
+node scripts/test-backup-integration.js --type local
+
+# Test with cleanup after completion
+node scripts/test-backup-integration.js --cleanup
+
+# Verbose output
+node scripts/test-backup-integration.js --verbose
+```
+
+## Test Coverage
+
+The test suite covers:
+
+### Configuration
+- ✅ Database configuration retrieval
+- ✅ JSON parsing and error handling
+- ✅ Configuration validation
+- ✅ Required field validation
+
+### S3 Functionality
+- ✅ S3 client initialization
+- ✅ Connection testing
+- ✅ File upload with progress tracking
+- ✅ Large file handling (multipart upload)
+- ✅ Metadata and custom headers
+- ✅ Error handling and retries
+
+### Backup Process
+- ✅ Full backup execution
+- ✅ Incremental backup (changed files only)
+- ✅ File checksum calculation and comparison
+- ✅ Database backup inclusion
+- ✅ Archive inclusion toggle
+- ✅ File size limits
+
+### Manifest Generation
+- ✅ Full manifest generation
+- ✅ Incremental manifest with parent reference
+- ✅ JSON and YAML format support
+- ✅ Manifest validation
+- ✅ S3 manifest storage and retrieval
+- ✅ Checksum verification
+
+### Error Handling
+- ✅ S3 connection failures
+- ✅ File read errors
+- ✅ Individual file failure recovery
+- ✅ Retry logic with exponential backoff
+- ✅ Email notifications on failure
+- ✅ Concurrent backup prevention
+
+### Backward Compatibility
+- ✅ Local directory backup
+- ✅ Rsync backup
+- ✅ Existing manifest format support
+
+### Service Management
+- ✅ Cron job scheduling
+- ✅ Service start/stop
+- ✅ Manual backup triggering
+- ✅ Backup history and status
+
+## Mock Setup
+
+The unit tests use comprehensive mocking:
+
+```javascript
+// Database mocking
+jest.mock('../../src/database/db');
+
+// S3 client mocking
+jest.mock('../../src/services/storage/s3Storage');
+
+// File system mocking
+const mockFs = require('mock-fs');
+
+// Cron job mocking
+jest.mock('node-cron');
+```
+
+## CI/CD Integration
+
+To run tests in CI/CD pipeline:
+
+```yaml
+# Example GitHub Actions
+- name: Run Unit Tests
+  run: npm test -- __tests__/services/backupService.enhanced.test.js
+
+- name: Start MinIO
+  run: |
+    docker run -d \
+      -p 9000:9000 \
+      --name minio-test \
+      -e MINIO_ROOT_USER=minioadmin \
+      -e MINIO_ROOT_PASSWORD=minioadmin \
+      minio/minio server /data
+
+- name: Run Integration Tests
+  run: npm test -- __tests__/integration/backup-s3.test.js
+```
+
+## Debugging Tests
+
+```bash
+# Run tests in debug mode
+node --inspect-brk ./node_modules/.bin/jest __tests__/services/backupService.enhanced.test.js
+
+# Run single test with console output
+npm test -- __tests__/services/backupService.enhanced.test.js -t "should perform S3 backup" --verbose
+```
+
+## Performance Considerations
+
+- Integration tests create real files and S3 objects
+- Each test run creates a unique S3 bucket to avoid conflicts
+- Cleanup is automatic but can be disabled for debugging
+- Large file tests (10MB+) are included but can be slow
+
+## Adding New Tests
+
+When adding new backup features:
+
+1. Add unit tests to `backupService.enhanced.test.js`
+2. Add integration tests to `backup-s3.test.js` if S3-specific
+3. Update manual test script for comprehensive testing
+4. Ensure mocks are properly configured
+5. Document any new environment requirements

+# Security Logging Documentation
+
+## Overview
+This document describes the comprehensive security logging implemented in the PicPeak application to track authentication failures, rate limiting, and suspicious activities.
+
+## Log Files
+
+### 1. **security.log**
+- Location: `logs/security.log`
+- Contains: All security-related events (authentication, rate limiting, suspicious activity)
+- Max Size: 20MB with rotation (keeps 10 files)
+- Format: JSON with timestamp
+
+### 2. **error.log**
+- Location: `logs/error.log`
+- Contains: All error-level logs including auth failures
+- Max Size: 10MB with rotation (keeps 5 files)
+
+### 3. **combined.log**
+- Location: `logs/combined.log`
+- Contains: All logs (info, warn, error)
+- Max Size: 50MB with rotation (keeps 10 files)
+
+## Security Events Logged
+
+### Rate Limiting
+When rate limits are exceeded, the following is logged:
+```json
+{
+  "timestamp": "2024-01-18 14:23:45.123",
+  "level": "warn",
+  "message": "Rate limit exceeded",
+  "security": true,
+  "ip": "192.168.1.1",
+  "path": "/api/admin/login",
+  "method": "POST",
+  "authenticated": false,
+  "userAgent": "Mozilla/5.0...",
+  "referer": "https://app.example.com",
+  "origin": "https://app.example.com",
+  "headers": {
+    "x-forwarded-for": "192.168.1.1",
+    "x-real-ip": "192.168.1.1"
+  },
+  "requestUrl": "/api/admin/login",
+  "rateLimitInfo": {
+    "limit": 5,
+    "current": 6,
+    "remaining": 0,
+    "resetTime": "2024-01-18T14:38:45.123Z"
+  }
+}
+```
+
+### Authentication Failures
+
+#### Admin Login Failures
+- Tracked in `login_attempts` table
+- Logged with: IP address, username, user agent, timestamp
+- Account lockout after 5 failures in 15 minutes
+
+#### Gallery Password Failures
+- Tracked in `access_logs` table with action='login_fail'
+- Logged with: event_id, IP address, user agent
+- Gallery lockout after 5 failures in 15 minutes
+
+### JWT Validation Failures
+```json
+{
+  "timestamp": "2024-01-18 14:23:45.123",
+  "level": "warn",
+  "message": "JWT validation failed",
+  "ip": "192.168.1.1",
+  "path": "/api/admin/events",
+  "method": "GET",
+  "userAgent": "Mozilla/5.0...",
+  "error": "TokenExpiredError",
+  "message": "jwt expired"
+}
+```
+
+### Suspicious Activity
+- Multiple IPs attempting login for same account
+- Token usage from different IP than issued
+- Token usage after password change
+- Revoked token usage attempts
+
+## Configuration Settings
+
+All rate limiting settings are configurable via the admin panel:
+
+| Setting | Default | Range | Description |
+|---------|---------|-------|-------------|
+| rate_limit_enabled | true | - | Enable/disable rate limiting |
+| rate_limit_window_minutes | 15 | 1-60 | Time window for rate limit |
+| rate_limit_max_requests | 1000 | 10-10000 | Max requests for general endpoints |
+| rate_limit_auth_max_requests | 5 | 1-100 | Max requests for auth endpoints |
+| rate_limit_skip_authenticated | true | - | Skip rate limit for authenticated requests |
+| rate_limit_public_endpoints_only | false | - | Only rate limit public endpoints |
+
+## Database Tables
+
+### login_attempts
+```sql
+- id
+- username
+- ip_address
+- user_agent
+- success (boolean)
+- created_at
+```
+
+### access_logs
+```sql
+- id
+- event_id
+- ip_address
+- user_agent
+- action ('view', 'download', 'login_success', 'login_fail')
+- photo_id (nullable)
+- created_at
+```
+
+## Environment Variables
+
+- `LOG_LEVEL`: Set logging level (default: 'info')
+- `LOG_TO_CONSOLE`: Enable console logging in production (default: false)
+
+## Monitoring Recommendations
+
+1. **Set up alerts for:**
+   - Rate limit exceeded events (possible DDoS)
+   - Multiple failed login attempts from same IP
+   - Account lockout events
+   - JWT validation failures spike
+
+2. **Regular review:**
+   - Check security.log for patterns
+   - Review login_attempts table for brute force attempts
+   - Monitor access_logs for suspicious gallery access patterns
+
+3. **Log analysis tools:**
+   - Use log aggregation tools (ELK stack, Splunk)
+   - Set up dashboards for security metrics
+   - Configure alerts for threshold breaches
+
+## Production Deployment Notes
+
+1. Ensure logs directory has proper permissions
+2. Set up log rotation outside of application if needed
+3. Consider shipping logs to centralized logging service
+4. Monitor disk space for log files
+5. Set `LOG_TO_CONSOLE=true` for container deployments
+
+## Security Best Practices
+
+1. Never log sensitive data (passwords, tokens)
+2. Use generic error messages to prevent user enumeration
+3. Clean up old login attempts regularly (7 days retention)
+4. Monitor for unusual patterns in real-time
+5. Keep rate limit settings appropriate for your usage

+# Database Migrations
+
+This directory contains database migrations for the Wedding Photo Sharing platform.
+
+## Directory Structure
+
+### `/core`
+Essential migrations that are always run for new deployments. These include:
+- `init.js` - Initial database schema creation
+- Backup service tables (029-035)
+- Gallery feedback tables (033)
+
+### `/legacy`
+Migrations needed only when upgrading from older versions. New deployments can skip these as the core schema already includes all necessary tables and columns.
+
+## For New Deployments
+
+If you're deploying this application for the first time:
+1. The `initializeDatabase()` function in `src/database/db.js` will create all necessary tables
+2. Only migrations in the `/core` directory will be run
+3. This ensures a clean, optimized database schema
+
+## For Existing Deployments
+
+If you're upgrading from an older version:
+1. All migrations (both core and legacy) will be run in sequence
+2. The migration system tracks which migrations have been applied
+3. Only new migrations will be executed
+
+## Running Migrations
+
+```bash
+# Development
+npm run migrate
+
+# Production
+npm run migrate:prod
+```
+
+## Note on Duplicate Migration Numbers
+
+The legacy directory contains renamed duplicates:
+- `014_add_host_name_to_events_duplicate.js` (was duplicate of 014)
+- `027_add_rate_limit_settings_duplicate.js` (was duplicate of 027)
+
+These have been renamed to avoid conflicts while preserving the migration history.

+/**
+ * Manual Integration Test Script for Enhanced Backup System
+ * 
+ * This script provides a comprehensive test of the backup system with real services.
+ * It can be used to test against MinIO, AWS S3, or other S3-compatible services.
+ * 
+ * Usage:
+ *   node scripts/test-backup-integration.js [options]
+ * 
+ * Options:
+ *   --endpoint <url>     S3 endpoint URL (default: http://localhost:9000)
+ *   --access-key <key>   S3 access key (default: minioadmin)
+ *   --secret-key <key>   S3 secret key (default: minioadmin)
+ *   --bucket <name>      S3 bucket name (default: test-backup-<timestamp>)
+ *   --type <type>        Backup type: s3, local, rsync (default: s3)
+ *   --cleanup            Clean up test data after completion
+ *   --verbose            Enable verbose logging
+ *   --help               Show this help message
+ * 
+ * Examples:
+ *   # Test with local MinIO
+ *   node scripts/test-backup-integration.js
+ * 
+ *   # Test with AWS S3
+ *   node scripts/test-backup-integration.js \
+ *     --endpoint https://s3.amazonaws.com \
+ *     --access-key AKIAIOSFODNN7EXAMPLE \
+ *     --secret-key wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY \
+ *     --bucket my-test-bucket
+ * 
+ *   # Test local backup
+ *   node scripts/test-backup-integration.js --type local
