Android equivalent of an icloud full backup

[abc123456789]

Ok, this will sound a bit thick but I've googled it and can't get a clear answer. 

 

I'm new to android and need to do a full backup, of everything. I want to keep my full res photos and all of my app data and messages if at all possible. On iPhone it was very simple and I'm looking for an android equivalent. Can I just plug the phone into my PC, copy the data across then be able to copy it onto a replacement phone?

 

I have a OnePlus 7 Pro if that information helps.

This is a good article I found to do so, I would just recommend a single change:

It says to get the entire andorid SDK, but in my opinion that is just unnecessary. You can get a minimal version which only has ADB and Fastboot here: https://forum.xda-developers.com/showthread.php?t=2588979

Does that backup the whole lot?

The instructions in the article don't work, It doesn't open the screen on my phone. It asks for USB Debugging permissions, i clicked allow and ran the command but nothing happened
