after temporarily stopping photo backup how do I restart without uploading all my pictures?

My mistake. I am referring to iCloud Photo Library. i had been uploading and storing my entire photo library to the cloud for easy access on other I devices. But because I planned on taking photos with my phone while traveling internationally, I disconnected from iCloud Photo Library to avoid the automatic upload and resultant data charges. Now I want to return to the previous state but I'm unable to figure out how to do so.

thanks

Youve identified my problem. I have the 25 GB storage plan ($11.99/yr) that I do not believe is available any longer. My photos take up about 16 GB; everything else about 5 GB. So, no, I can't remove enough stored data to make room for the photos. I could temporarily increase storage space for a month but then i dont think I could go back to the 25 GB plan. The cloud won't let me start uploading until I increase storage space. I could do a local backup and delete all photos on iPhone and sync with cloud, I guess.

THanks again

Thanks for identifying albums issue. I've got call with Apple scheduled, so we'll see what they say.

Thanks again

I spoke with an Apple CSR that, contrary to my previous experiences, was very helpful and knowledgeable. He understood my problem immediately and walked me through some simple, but not successful, potential solutions. His recommendation: back up all my photos and videos locally and delete enough files from icloud.com to open up enough space for things to work again. I deleted almost all of my saved videos, but none of the pictures, and things seem to be working again. The videos are (very slowly) backing up to iCloud. Hopefully, they will all be uploaded in a few days.

The CSR also suggested that the next time I want to avoid inadvertently uploading pictures and videos to iCloud, go to Settings>Cellular and click iCloud off of the list of apps using cellular data.

Thanks for your help
