iMac photos to iCloud issue?

Hi- I have 350 GB library of 70,000 photos and am trying to move to 2TB iCloud for first time. It's just not uploading- my library is so big. How can I get this to work?

That size of library will take time. It is not a simple FTP upload.

And to be clear, you are not moving those files. iCloud Photos is a syncing service, not off device storage.

To some degree, your photos will be present on both your Mac and iCloud.

If something happens to my Mac, all of my pictures will still exist in the cloud, yes? If my Mac dies and I don't get another Mac, will I still be able to use my pictures in the cloud as I normally would?

If you keep them synced, yes.

Your photos were not "moved" to iCloud. That's the term you used. Your photos are still present on your Mac, in addition to being on iCloud.

If your Mac crashes, signing in to iCloud again will sync your photos from iCloud back to your Mac.

It is key you understand that you can't now delete photos from your Mac, using the logic they are in iCloud.
