Photos uploading library again after restoring Mac from backup

Thank you, Eric 🙂

Exactly! It's not clear what it is doing. After a few hours it says it has uploaded 7GB. Has it really uploaded 7GB worth of data or has it checked 7GB worth of data? The whole process seems ridiculous. For example dropbox doesn't re-upload your whole dropbox to check itself.

And if it is just checking the iCloud library with the local copy, then that is what it should say it is doing!

It is just comparing the two.

You can check with the Network Utility.app, how much traffic the upload is creating. In Sierra the Network Utility has been moved to /System/Library/CoreServices/Applications/Network Utility.app/

When I checked the Info tab when Photos said it was uploading again, the number of packets transmitted had been very high -several GB of data had been transmitted. A TCP packet can have up to 64kb.

I have this problem too, but I didn't even do a restore. I just noticed new photos weren't showing up in Photos, so I looked at the the preferences and iCloud Library had been mysteriously shut off. I turned it on again and now its uploading 200GB of images again. I even had to upgrade my iCloud plan to hold the images that are presumably already there!

This could easily be done with a checksum instead of a file upload. Very sloppy programming on Apples part!

Send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.

Feedback

They won't read it either. I'm convinced feedback goes to /dev/null
