Anybody know what I am doing wrong? I have over 6000 photos and 500GB of storage and only around 400 photps are backing up. Why?
To make sure I've understood correctly, do you mean you have about 6000 photos on your iPhone, but only about 400 of them have backed up onto BT Cloud?
If so, here are some things to check:
If the photos definately aren't making it onto BT Cloud and they aren't duplicates then it sounds like a problem you'd need to contact BT about. My advice would be to contact a mod using the link in their signatures, and post to let us know how you got on. It does sound like an odd one - I have lots of photos set to back up from my iPad and have never had an issue like what you're describing.
Good luck with it!
