Backups are usually encrypted from most popular backup programs, either by default or as an option (restic, borg, duplicati, veeam, etc…). So that would take care of someone else getting their hands on your backup data.
For local data on my devices, my laptop is encrypted with bitlocker, and my Android phone is by default. My desktop at home is not though.

That’s why you use encryption.
