I started using iCloud for storing my photos, thinking it wold be a good backup. But then I realized that if, for example, my iPhone was stolen, and I needed to completely wipe it from another device, all my photos on the iPhone would be wiped. That also means that they're deleted from all my other devices, including my iPad and Mac because the iPhone deletes them from iCloud, right? The whole idea of ICloud is that it syncs all devices, so if a photo is deleted from one device, it's also deleted from all others and iCloud. Am I missing something? Isn't it dangerous to rely on iCloud as a backup?
