+## 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%

+# 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
+```
+

+
+### 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

+/**
+ * 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

+PicPeak Restore Service Test
+
+This script tests the restore service functionality with safety checks.
+
+Usage:
+  node scripts/test-restore-service.js [options]
+
+Options:
+  --dry-run    Perform validation only without actual restore
+  --force      Force restore even with warnings
+  --type       Restore type: full, database, files, selective (default: full)
+  --source     Backup source path or S3 URL
+  --manifest   Path to backup manifest
+  --help       Show this help message
+
+Examples:
+  # Dry run with automatic backup selection
+  node scripts/test-restore-service.js --dry-run
+
+  # Full restore from specific backup
+  node scripts/test-restore-service.js --source /backup/2024-01-20 --manifest /backup/2024-01-20/manifest.json
+
+  # Database-only restore with force
+  node scripts/test-restore-service.js --type database --force --source /backup/2024-01-20 --manifest /backup/2024-01-20/manifest.json
+
+  # Restore from S3
+  node scripts/test-restore-service.js --source s3://my-bucket/backups/2024-01-20 --manifest s3://my-bucket/backups/2024-01-20/manifest.json
+
+Safety Features:
+- Pre-restore validation checks compatibility and warns about potential issues
+- Automatic pre-restore backup is created (unless skipped)
+- Post-restore verification ensures data integrity
+- Rollback capability if restore fails
+- Detailed logging of all operations
+`);

+- created_at
+- database_dump_path
+- database_checksum
+- files_manifest (JSON with all file paths/checksums)
+- metadata (JSON with system info, versions, etc.)
+
+-- restore_operations table
+- id (primary key)

+  backup_destination_type: "s3",
+  backup_s3_endpoint: "https://s3.amazonaws.com",
+  backup_s3_bucket: "wedding-backups",
+  backup_s3_access_key: "AKIA...",
+  backup_s3_secret_key: "secret",
+  backup_s3_region: "us-east-1",
+  backup_s3_use_ssl: true,
+  backup_s3_path_style: false
+}
+```
+
+### MinIO Configuration:
+```javascript
+{
+  backup_destination_type: "s3",
+  backup_s3_endpoint: "https://minio.example.com:9000",
+  backup_s3_bucket: "picpeak-backups",
+  backup_s3_access_key: "minioadmin",
+  backup_s3_secret_key: "minioadmin",
+  backup_s3_region: "us-east-1",
+  backup_s3_use_ssl: true,
+  backup_s3_path_style: true // Required for MinIO

+## Best Practices Implementation
+
+1. **Change Detection**: Use database triggers and file checksums to detect changes
+2. **Compression**: Always compress before encryption for better ratios
+3. **Chunking**: Split large backups into manageable chunks
+4. **Versioning**: Keep multiple backup versions with rotation
+5. **Validation**: Verify every backup immediately after creation
+6. **Monitoring**: Alert on backup failures within 5 minutes
+7. **Testing**: Perform monthly restore drills
+8. **Documentation**: Log every backup/restore operation with details
+
