Hello, In the situation you have described, if i understood well, you would not have any space. When you take a snapshot, your snapshot is referencing the blocks older than it... Ex.: You have a 500gb disk, and create a 5gb file, you got 495gb free space. So you delete the file, you have 500gb again. But if you take a snapshot *before* delete the file, that file is still there (in the snap), and using space (5gb)... ;-)
