The thing they don't tell you, how do you get your Volumes of data to the Cloud?
I've heard this limitation is being worked on to streamline a process.
There are existing tools similar to Windows Explorer to facilitate this process.
However, they seem to be manual.
I've actually heard someone say they ship their hard drive to the Cloud provider.
Strange but true.
Someone will need to find a working solution to this issue.
Because you can't have Big Data with out lots of Data.
