• Comprehensive Backup: Supports repositories and gists (public and private with token)
• Concurrent Operations: Configurable number of concurrent operations
• Production Ready: Proper error handling, logging, and configuration management
• Configurable: Multiple ways to configure the tool (flags, environment variables)
• Rate Limiting: Built-in rate limit handling for GitHub API
• Docker Support: Easy deployment using Docker
• CI/CD Ready: GitHub Actions workflow for automated testing and deployment
