What's the best way to achieve this automated backup?

To preface: I've already been doing this via Macrium however it's kinda uncomfortable or not optimal because I have to mount the folder backup as a virtual drive to access its contents.

So because of this, I've written the following script:

Code:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

$Source = "C:\Users\(USERNAME)\Scripts"


Import-Module -Name BurntToast


function ShowNotification {
    $NotificationMessage = "All files copied from $Source to $Destination"
    New-BurntToastNotification -Text $NotificationMessage 
}


function CopyFiles {
    Write-Host "Copying files from $Source to $Destination"

        $sourceFiles = Get-ChildItem -Path $Source -File -Recurse

    foreach ($sourceFile in $sourceFiles) {
        $destinationFile = Join-Path -Path $Destination -ChildPath $sourceFile.FullName.Substring($Source.Length + 1)

        
        if (!(Test-Path -Path $destinationFile) -or $sourceFile.LastWriteTime -gt (Get-Item -Path $destinationFile).LastWriteTime) {
            Copy-Item -Path $sourceFile.FullName -Destination $destinationFile -Force
            Write-Host "Copied " -NoNewline
            Write-Host "$($sourceFile.FullName)" -ForegroundColor Red
        }
        else {
            Write-Host "Skipped " -NoNewline
            Write-Host "$($sourceFile.FullName)" -ForegroundColor Green
            Write-Host " (already up to date)"
        }
    }

    Write-Host "Copying complete."
    ShowNotification  # Display the notification
}


while ($true) {
    # Check if USB drive is connected
    $usbDrive = Get-WmiObject Win32_Volume | Where-Object { $_.DriveType -eq 2 -and $_.Label -eq "USB-C-Drive" }

    if ($usbDrive) {
        $Destination = Join-Path -Path $usbDrive.DriveLetter -ChildPath "downloads test mappa"
        Write-Host "USB drive found. Copying files..."
        CopyFiles
    }
    else {
        Write-Host "USB drive not found. Waiting..."
    }


    
    Start-Sleep -Seconds 10
}

Ideally the event trigger would be the plugging of a USB flash drive into the PC but all the articles I have found regarding that seem to make it an even less desirable way to get this working

Is there a way to do this in a simpler, more comfortable manner? The script works, I'll even refine it if needs be, but I need to make this trigger event more simpler and convenient.
