====== VMCTL sizing (indexing VM backup) ======

In summary:

    Original source data = 100 GB
    Total retained data = 100 GB + (100 GB * .10 change rate * 15 days) = 100 GB + 150 GB = 250 GB
    VMCTLMC data required = 250 GB * 0.002 VMCTLMC estimate = 0.5 GB

Remember that this is an approximation.
