Backing up Google Photos?

Can you arrange for the SD Wireless Stick to auto back up photos from your Google Photos app rather than or in addition to the photos in your Gallery app?

If not is the only way to achieve this is to manually back up photos from your Google photos?

Thanks

Looking for  an answer to previous question regarding accessing photos from Google rather than gallery on my iPad using Sandisk iXpand 64.  Is it possible?
