I was wondering, when you store files on iCloud Drive in Yosemite, are the files also locally stored? I'm asking because I'm getting myself a new rMBP. If I like it, and decide to keep it, if I do 200gb of iCloud Drive, I'll plan to have all my data stored there. However, I keep all my data on a separate partition (to reduce chances of corruption from the user account). My question is, would the data I upload to iCloud Drive be kept locally on Yosemite, or would it be online only? I don't want storage to be limited due to everything being on iCloud Drive AND on my other partition (I've got 512GB for the SSD space, and about 150GB of data). Does that make sense?
