Backing up photo folder to google photos

I don't quite follow how you are trying to "back up to Google Photos" -- in the screenshot I see Google Drive which does not work for that.

Anyways, in my experience sometimes uploading many images from some Finder folder via Safari to Google Photos might stall. If that happens, I have switched to uploading via Firefox which has then worked.

It sounds like you're using iCloud Photos-- is that right? Are you using Optimize?

You didn't show the path to your Pictures Folder-- is it in your Home (User name) folder? Or is it somewhere else?

Your statement " i cannot update until i have more storage" is troubling. Your OS is the most current. How much storage do you have on your internal drive? At System Settings>General> Storage, my Mac says 745 GB of 1TBB used. What does yours say?

The Photos Library is not a Folder but a Package, and it has some special properties. It can't work from iCloud Drive or from Google, for instance. If you use Optimize, then saving the Photos Library Package would not back up your pictures.

Give us more information so we can help…

It's going to be important to get this straight. In Photos' Settings>iCloud

have you chosen "Download" or "Optimize?"

Optimize is a service of iCloud that reduces the storage of your picture by as much as 90%. You should see this:

It's also important to know about your Mac's storage: At System Settings>General> Storage, my Mac says 745 GB of 1TBB used. What does yours say?

I can see that your Photos Library Package is in your Home Folder's Pictures folder. That's good. And you're trying to copy this to Google Storage. I don't do Google, but that should be OK for a backup, as long as you don't try to access it there with the Photos app. Your Photos Library must stay in that Pictures folder.
