If iCloud backup is off, are the toggled items still being put on iCloud?
If iCloud Backup is off, then your device is not being backed up to iCloud, regardless of any other settings.

Enabled iCloud services will synchronise that data to other devices with those services on. In the screenshot, the Contacts and Calendars services are enabled, which means that the data which is stored in iCloud for these services will be synchronised to all devices with these services enabled.
