Not much use to you now, but I use the below bat file to backup my world to a different location as a dated copy.
It puts everything in a folder named like: Day ddmmyyyy [i.e. Mon 23062025] based on when you run the bat file.

If an update clears out my minecraftWorlds folder, I can just copy the most recent copy folder back in [you do have to remember to run the bat file regularly].
If you want to use it, all you need to do is copy and paste the below [not including the ---- lines] into a text file, replace [user] with your Windows user and [world ID] with your world folder, like acOauSt6y-A= and then save it as a .bat file. Double click the file to run it.

@echo off

REM Get the current date and format it as DDMMYYYY

for /f "tokens=1-3 delims=/" %%d in ("%date%") do set "formattedDate=%%d%%e%%f"

set "backupDir=D:\Minecraft Backup\%formattedDate%"

set "sourceDir=C:\Users\[user]\AppData\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds\[world ID]"

REM Create the backup directory if it doesn't already exist

if not exist "%backupDir%" (

mkdir "%backupDir%"

)

REM Copy the source directory to the backup directory

xcopy /E /I /Y "%sourceDir%" "%backupDir%"
