iCloud drive file with cloud icon with line through it
My Photos library has gotten kinda unwieldy, so my plan is to duplicate the library, calling the one the archive with all the photos and make the orginial the system photo library and delete many of my older photos. Those photos will of course be backed up through the iCloud photo library and remain visible to all my iOS devices. The archive library will remain accessible when I open Photos holding down the option key, but will not be backed up. So I thought, since I have plenty of space on my icloud drive, I would copy and paste a copy there from the Finder, in addition to saving a copy on my computer at work. The file is about 7GB, well under the 15GB file size limit for iCloud drive. Problem is the file has a cloud symbol with a line through it. Does this mean I can't save a copy to my icloud drive?
