social.technet.microsoft.com › Forums › en-USMar 04, 2016 · You install an OS and only 14Gb of physical storage is used. You then take a Checkpoint. Now, you have the root 14Gb, and the potential to consume another 127Gb of storage. Time passes and this Checkpoint consumes 50Gb of storage. 14 + 50 = 64Gb consumed. You now take another Checkpoint. and all kinds of stuff happens in that VM OS.
