Apple seems to be pushing iOS devices as a main computing platform, and without connecting to a PC or Mac the best way to store photos seems to be iCloud Photo Library. But the best I can find is that they still recommend a PC or Mac to back up the library. So there's no real way to drop the PC if I want to rely on iCloud to back up my photos when using an iPad as a main device. What is the "Apple Way" to do this? Are we still stuck manually backing up our library? Do you have multiple iCloud accounts if you get above 1TB of data?
