For music/photos/videos, you can just connect it to your PC and copy/paste the files you want to save.

For app data, go to Settings > Update & Security > Backup and make sure you have toggled both "Back up content from participating apps" and "Back up settings like my Start screen layout, accounts and passwords". And if you go into the "More option", you can see which app data can be backup on the cloud.

Do note that WhatsApp does not support Windows Phone cloud backup system so if you hard reset, you will lose all of your Whatsapp messages/pictures/videos. There is a way to backup/restore WhatsApp messages, but only if your phone has a SD card slot and I personally never done it so proceed at your own risk.

For contacts, if you have linked the phone with a Microsoft account, it should already be saved on the cloud. Check on this site to see if all your contacts is in there : https://people.live.com/

For SMS, again if you have linked the phone with a Microsoft account, it should already be saved on the cloud. After you have hard reset, be sure to go to System > Messaging and set the "Download messages from" option to "Any time"
