While you can backup iPhone using both iTunes and iCloud, there is a crucial difference between iCloud and iTunes Backup of iPhone that you need to understand.

What is Not Included in iCloud Backup?

Also, iCloud Photos and Photos downloaded from WhatsApp and other Apps are not included in an iCloud Backup.
