Backup System

A simple Python-based backup system that automatically backs up files from a specified folder, calculates file hashed, and stores metadata in a MySQL database. Supports versioning of files and includes tests.

---

Features

• Scans a watch folder for new or modified files (manual scans for now)
• Creates timestamped backups of files
• Calculates SHA-256 hashed to detect changes
• Stores file metadata and backup history in MySQL
• Includes Dockerized MySQL for easy setup
• Makefile for running and testing
• Fully tested with 'pytest'
