@Shan McDonell I used to handle GeneChip image size up to several GB size and I feel your pain. I suggest you can just file:///path to your local image. If you want to do backup, you can just grab a hd, or burn to BDisc. It sucks to transfer such huge size to the cloud. However, lan to lan transfer I recommend either bittorrent sync or Syncthing.
