Sometimes you need to create a backup of your phone data.

Select Menu > > Backup > Create backup.
Your device tells you that creating a backup may take a while and that you should not turn the phone off while the backup is created. Select Choose if you want to create a backup.
A list opens where you can mark the data you want to backup. You can Mark them one by one, or select Options > Choose all.
Your phone tells you when the backup is created.
