Backup

Good day

I am uncomfortable with the idea of cloud storage. My data is mine and Norton should not be able to access it and copy it from my computer. I cannot find any solution other than performing backups. Nowhere can i find a way to stop the backup.

Please help me to find the setting that allows/disallows the backup feature. My data is regularly backed up on my external hard drive. In 30 years of computing i have never experienced any hardware failures. Hope that statement is not tempting fate.
