title: How to backup Anaconda added packages?
body: <p>I have Anaconda for Python 2, It came packed with a lot of useful packages. During my work, I have added several packages to it using <code>conda install</code> command. Now I have to format my system, and I want to backup/pack all the added libraries, either as full packages or even by knowing the installation command of each one.</p>
  
  <p>I searched <a href="http://stackoverflow.com">StackOverflow</a>, I found one <a href="https://stackoverflow.com/questions/39293263/how-to-back-up-python-and-dependencies">unanswered question</a> with a similar problem, the question suggested <code>conda list -e &gt;file_list.txt</code> to create a file contains all the installed packages, but this is not sufficient for me, I want Anaconda to determine which package is added by me, and by which command, or to pack the added packages in full. </p>
  
  <p>Thanks for help.</p>
