If I make the move to iCloud Photo Library, is there a way to still backup my photo library to an external hard drive as I do now? My concerns are about the unlikely chance that my login ID is compromised or Apple somehow loses part of my library. I know that this is unlikely, but I don't like the 1% chance of my login being stolen and having my daughter's lifetime of photos being deleted. Am I crazy? I like the security of my own backup, but want the convenience of the cloud.
