title: Specify destination directory for Laravel Spatie backup
body: <p>I'm using <a href="https://github.com/spatie/laravel-backup" rel="nofollow noreferrer">Laravel Spatie Backup</a> to backup my Laravel project. Right now the backup gets stored in the <code>myproject/storage/app</code> directory. How can I change this directory to for example <code>myproject/storage/app/some/directory</code>? 
  I can't find a clear answer on this.</p>
  
  <p>My <code>laravel-backup.php</code> config right now:</p>
  
  <pre><code>'destination' =&gt; [
  
      /*
       * The disk names on which the backups will be stored.
       */
      'disks' =&gt; [
          'local'
      ],
  ],
  </code></pre>
  
  <p>I tried the following: <code>'local' =&gt; '/some/directory'</code> but this throws the error  <code>Copying .zip file failed because: Could not connect to disk /some/directory because the disk is not set..</code></p>
