.. include:: /Includes.rst.txt .. _backup: ====== Backup ====== Make a backup first! If things go wrong, you can at least go back to the old version. You need a backup of * all files of your TYPO3 installation (by using FTP, SCP, rsync, or any other method) * the database (by exporting the database to an SQL file) Also you may prefer to upgrade a copy of your site first, if there have been a lot of changes and some of them might interfere with functions of your site. See the :doc:`changelog ` to check that. For more detailed information about TYPO3 backups see :ref:`t3coreapi:security-backups` in *TYPO3 Explained*.
