Manny wants to store his photos in the cloud, but he wants to have a better quality image stored locally. Leo says that iCloud always keeps the higher quality image in the cloud. In Google Photos, he can turn off "optimize photos" and it will keep the higher quality locally as well. But Leo says he really won't see the difference.
How can Manny back up to the cloud and then keep the full quality locally also? Leo says syncing with iTunes is the way to do that. Either connected or via Wi-Fi sync. Time Machine is also a good way to create a local backup copy as well. He should just make sure it's on a secondary drive. This is the reason that Apple does this.
