Preventing backups of duplicate photos

Hi gurus,

I have a onedrive account that is synced to my phone and my personal laptop. OneDrive automatically backups all photos that I've taken on my phone.

Periodically, I will organise and move my photos from phone to my laptop to 'free up' phone storage - I will categorise the photos in folders in my laptop. In this case, do you know if onedrive will backup these same photos again - meaning I will backup the same photo twice - phone version + laptop version?

How can I get Onedrive to backup the laptop photos, but to detect that it is a duplicate of the phone photos, and keep only the laptop photos?

Thanks!
