Hello I need to upgrade my Wiki 1.18. Can I make a direct upgrade to 1.22 or I have to do it step by step? I have the database on an FTP server. Do i have to make a backup of the database or only of the program files?

You can make a direct upgrade, as update.php includes all the changes that need to be made in the database. The most important things to backup are the database (as it stores all your articles) and the images folder (as it stores all uploaded files). You may want to backup LocalSettings.php as well.
