title: Create tar archive without folders where only the name of the folder is known (recurring)
body: <p>I have a synology DS213j. I have installed PhotoStation on it and it created some @eaDir folders in all my folders in order to create some thumbnails pictures.
  I have for example this:</p>
  
  <pre><code>/photo
  /photo/2012
  /photo/@eaDir
  /photo/2012/Album1
  /photo/2012/Album2
  /photo/2012/@eaDir
  /photo/2012/Album1/SubAlbum1
  /photo/2012/Album1/SubAlbum2
  /photo/2012/Album1/@eaDir
  </code></pre>
  
  <p>I would like to tar my folder 2012 in order to send that to Amazon Glacier for backup. I don't want to use .zip because I may have some files of more than 4Gb which is too much for zip.</p>
  
  <p>I have done this:</p>
  
  <pre><code>tar -cvzf 2012.tar.gz 2012/
  </code></pre>
  
  <p>It worked but included all the folders named @eaDir.</p>
  
  <p>My questions is. I would like to exclude all the @eaDir folders from my tar file.</p>
  
  <p>I have tried to use the --exclude function but it seems it's not valid on the Synology. Maybe I need to install another package to have another tar function to be able to use that. Maybe I can use regex function in order to achieve what I want.</p>
  
  <p>Can someone help me with that? (with --exclude or regex or anything else)</p>
