How to automatically retrieve the contents of websites erased or missing

Very often when you publish content on the Internet, you do not taking into account all the consequences that such action may have, first of all that nothing can be truly removed from the Web, whether it's the pages on his blogs of personal data that lately all love scatter everywhere on Facebook.

  • Internet Archive (which is also based Wayback Machine)
  • Google's cache
  • Yahoo cache
  • Live Search cache

  At the end of the process, which may take several days (it all depends on the amount of pages), Warrick will send you an email with instructions to download a zip file containing the contents recovered. It 'very interesting that Warrick is also available as downloadable Perl script and therefore manageable directly from your computer via the command line.

• correct information
• the use of reason
