google-photos
Yesterday I joined the Google Photos new service.
I selected huge libraries ( images and videos) and dragged them to the browser for upload.
It is already taking 3 days now (uploading)
Question:
what if my computer goes shutdown for some reason ?
I know that I will have to do it again since it doesnt skip existing files.
Is there any solution to this scenario where browser is closed / computer gets shutdown /reset or something ?
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.
If you have the Google Photos saved in your Google Drive, you should be able to install the Google Drive for Mac / PC to get the folder 'mounted' on your computer.
From there, you can use an application such as dupeGuru (which works on Mac and Windows). You should be able to scan the Google Photos folder within your Google Drive and find the duplicates.
dupeGuru Actions -- Do whatever you want with your duplicates. Not only can you delete duplicates files dupeGuru finds, but you can also move or copy them elsewhere. There are also multiple ways to filter and sort your results to easily weed out false duplicates (for low threshold scans).

I was wondering the same thing when I had to shut down my computer yesterday during a 3000+ photo transfer. It seems to skip duplicates now that I upload them again. I tried just uploading a folder of ~20 photos that were already on my google photos and it chugs through them as usual (uploads them) but there's just one copy in my library so it seems to have some way of skipping duplicates.
