Automatic backup from FTP to Google Drive

I wrote a background service for automatic file transfer from an FTP server to Google Drive cloud storage.

Main features:
— Synchronization on a scheduled basis
— File updates without creating duplicates
— Minimize to tray, background operation
— Auto-start with Windows via the registry
— Graphical interface with a timer and live log

Technical details:
— Python 3
— Google Drive API, OAuth 2.0
— ftplib, threading
— Tkinter + ttkbootstrap

The project is implemented "turnkey."
