Not really, since each "incremental" is only "a few G", that implies you
need 300G + 60 X 3G = 480G total for two months incrementals....

Remember, just because you take a full backup, doesn't mean you need a
full backup worth of storage space, because 95% of the files in this
full backup are identical to last weeks full backup!

Hope I didn't mis-understand what you were saying above...
