When I upgraded to Sierra, I approved using iCloud for storing my documents and files. What I didn't fully appreciate was that they would also be removed from my local HDD! So in order to have a local copy for when the Internet is out, or when Apple has a problem with their servers, I now need to make a clumsy manual backup of my iCloud documents on occasion to my local drive. I'm really unimpressed that Apple didn't allow some options, like syncing to duplicate files in iCloud. Thst is really what I would like to have. Comments?
