In order to have your own copy of the blockchain data you may (if you have sufficient technical knowledge) set up your own RPC node. It will likely cost more than $200USD per month though, and this cost isn't exactly reimbursed. Only when Witnesses 'produce blocks' are they paid for their work.
The approach @steemreports takes is to download some of the data to our server, but not the full blockchain, and also use the public RPC nodes where needed.
