All I have to do to Backup my phone, apps, folders, photos settings or the iPhone folders and apps is Icloud backup right?

Yes, but I would also recommend you do the following and go to:

Settings > Your Name, Apple ID, iCloud, iTunes & App Store

Tap iCloud

Turn on everything you want to back up to the cloud such as Photos, Messages, Notes, Calendars, Reminders, etc.

Once you've turned on ALL the service you want backed up, your phone will backup automatically, when it is plugged in to charge and connected to Wifi

You're very welcome. Take care and stay healthy!
