How do I backup my Redmi Note 9?

[AlreadyTaken]

(Im not rooted btw, nor do I have a custom recovery, I want to install it and thats why im backing up so bootloader unlock doesnt delete everything)
The phones backup tool in the settings is absolutely useless, backs up nothing important, and most of the time just nothing in general, adb backup doesnt work, it just gets stuck and im not even sure it backs up pictures.
What I want is to backup EVERYTHING (Contacts, SMS History, Home Screen Layout, App Data's, Photos/Videos (all media))

Contacts, sms, media is handled quite well by mi cloud (if you have free space), any non-root solution to app data backuping will always be subpar.

alright, by the way can you tell me how to install shrp (only officially supported for my phone) safely? (if you know ofc)
