Anyone who understands the issues involved here should carefully and closely look into the Qortal decentralized data network. It is free. You can post all your data on the QDN, a decentralized network of tens of thousands of independent nodes. The goal is an ineradicable, un-censorable repository of data of all kinds.

Running an independent Qortal node is not necessary but a good idea, and this is free aside from whatever hardware one chooses to use. It is easier than ever to set up a node to run 24/7/365, and thus become part of the repository.
