 The Updater App is not required, and it is recommended to use other methods for 
 keeping your ownCloud server up-to-date, if possible. (See :doc:`upgrade`.) The 
 Updater App is useful for installations that do not have root access, 
 such as shared hosting, and for installations with a smaller number of users 
 and data.

 You should maintain regular backups (see :doc:`backup`), and make a backup 
 before every update. The Updater app does not backup your database or data 
 directory.
