My Macbook has only 250GB harddrive but I want to store about 200GB in the icloud. How can I store documents in the cloud so I can access them from my ipad or other computers without keeping a copy on my Macbook? If this is not possible, is there a service to do this? I don't want to keep the documents on an external harddrive because I want to be able to access them when I am away from home. What allows me to keep documents only in the cloud but without a mandatory copy on the computer. Dropbox doesn't do it either. If I delete from either iCloud or Dropbox on my computer it also deletes from the cloud.
