I researched a lot this topic, found some great books and some not so great. My top in my recommended reading order:

• The Object-Oriented Thought Process, 5th Edition
• Head First Object-Oriented Analysis and Design
• Head First Design Patterns, 2nd Edition
• A Philosophy of Software Design

I had use Duplicati and Kopia. Duplicati works kinda well, the problem is the installation is such a pain in the ass, actually it never work as intended, that’s why I switched to Kopia, the installation is a lot easier, have GUI and and system tray icon, have better documentation, the Google drive backups with GUI requires a liltle configuration of rClone , nothing crazy

Can’t be the only one that had read it as Threesome

The Odin Project

PubDOS sounds better IMO

Protest about reddit using reddit is not a great idea
