Great comment. The key here, in case people miss it, is to ensure the originals are downloaded to your Mac, if you're going to back up photos to Backblaze. Otherwise, you'll just be backing up thumbnails and/or very low quality copies of your photos. If your internal storage isn't enough to hold all your images, you can move your photo library to an external volume. https://support.apple.com/en-us/108345 https://support.apple.com/en-us/108345
