title: Where to call resource for this backup-cookbook
body: <p>I am trying to use <a href="https://github.com/gofullstack/backup-cookbook" rel="nofollow">backup-cookbook</a>, and it's my first time trying to use the resource.</p>
  
  <p>However when I try to call the resource "backup_model" it complains "Cannot find a resource for backup_model". So I know I must have put it in the wrong place.</p>
  
  <p>I use librarian-chef. I am using chef-solo on a local Vagrant server.</p>
  
  <p>site-cookbooks/c/recipes/default.rb</p>
  
  <pre><code>backup_model :ct_backup do
    ...
  end
  </code></pre>
  
  <p>roles/backup.rb</p>
  
  <pre><code>name "backup"
  description "Backup role."
  run_list(
    "role[base]",
    "recipe[backup-cookbook]"
  )
  </code></pre>
  
  <p>node.json</p>
  
  <pre><code>{
    "run_list":[
      "role[base]",
      "role[backup]",
      "recipe[c]"
    ]
  }
  </code></pre>
  
  <p>When I try to run <code>knife solo cook</code> I got the following errors:</p>
  
  <pre><code>NameError
  ---------
  Cannot find a resource for backup_model on ubuntu version 12.04
