📖 Overview

This project is a production-style Python daemon that continuously monitors system resources while watching selected directories for filesystem activity. Whenever changes occur, it intelligently creates versioned ZIP backups, maintains backup history, and provides a command-line recovery interface.

The application demonstrates practical software engineering concepts including:

• Event-driven programming
• Background services
• Concurrent execution
• Filesystem monitoring
• Automated scheduling
• Logging
• Configuration management
• Fault-tolerant automation
