Backup ****** From `Backing up a site`_ Backup the MySQL database using standard MySQL commands. It is recommended to have a backup of *ALL* the files in case any have been modified. If you don't backup everything: ``/sites/all/modules/`` Failure to do this may leave you with no clear example of which modules you had, and what versions they were. *Administer*, *Site Configuration*, *File System* The folder where (uploaded) files are stored. On my site: ``sites/default/files`` ``/sites/`` Contains themes, logos and embedded images. .. _`Backing up a site`: https://drupal.org/node/22281
