I've installed Google Photos on my iPhone with the auto-backup feature.

I also have the possibility to install the backup feature on my Mac.

The problem is that iCloud syncs my iPhone pictures with my Mac. So I am afraid if I install Google Photos on my mac I'll have thousands of duplicates.

Is Google Photos smart enough to detect duplicates?

  • I was wondering the same thing, and a further complication is that the iCloud photo syncing between devices puts highly compressed versions on the non-source device.

Short answer

Google Photos appear that has a duplicate prevention feature that avoid to create duplicates on uploading time but it's not documented, so proceed carefully.


Use Picasa instead of Google Photos to backup your Mac photos.

  • It most certainly does and has done since the start that I'm aware of. Try uploading a photo, then uploading the same photo. It will check if the metadata is the same, and if so, will not upload it.
