Now we are going to configure the backup destination. Choose the backup destination from the list. You can choose from many types of backup destination including local and remote storage. In this example, I am going to use Box as my backup destination.

If you choose remote destination such as Box.com or Dropbox or any other remote destinations, click AuthID link to generate the AuthID. You will be redirected to your remote or cloud storage login page. Enter your login detail when asked.
