If you don't configure the destination disk properly, it will be very hard to understand what's happening because this message:

"Endpoints must be full URIs and include a scheme and host"

Is hidden by the exception handler:

public static function create(string $diskName, string $backupName): self
{
    try {
        $disk = app(Factory::class)->disk($diskName);

        

We need a special zip file that cannot be created with normal commandline tools. It requires crafting with an API. This should be possible with archive/zip#Writer, for example.

We want a double entry of a file - the first being a symlink such that the second will be placed in an arbitrary location:

./goodfile.txt  "hello world"
