If the original VM has a size of 60GB then the backup will be 60GB.

The current UI allows the customer to launch using 10GB but the launch will fail since the original image size is 60GB.

We'll check if the base backup image saved can be reduced in size.

To mitigate users running into errors in this case,

If a user selects a VM Size that is Lower than Backup Size, then VirtEngine must create a label in the launcher noting:

'Since your backup image is XXGB, while your selected plan only includes: XXGB of Storage - the VM launched will include XXGB of Storage added to your VM. Cost = $0.XX/hour, $XX/mo'

Then we automatically resize the plan to the required storage on launch.
