I have the same concerns, even though today I use OneDrive. My ideal solution would be a NAS that replicates my (encrypted) data across a peer to peer network of similar NAS'es, and so you would only be able to store personal data on a certain portion of the hard disk, and the other part would be used to replicate data from other NAS'es on the network. My data would be pretty safe: if the drive crashes I can just insert a new hard drive and the NAS starts reconstructing my data from the network again given the encryption key. Also, this NAS would be accessible from outside of my home network, so it's like my own cloud backed up on a peer to peer network. I would actually like to build this at one point. The hardware is pretty easy, take a Banana Pro board + a SATA drive and you have a wifi connected NAS. Building the software for the peer to peer network would be a bit trickier to make it work well. Anyone knows if a peer to peer network like this already exists?
