Currently I am researching options on Open Source Cloud solutions.

https://creativeoverflow.net/the-10-best-alternatives-to-dropbox/ is about 10 alternatives to DropBox.

http://www.tecmint.com/free-open-source-cloud-storage-tools-for-linux/ is another article on a few options.

OwnCloud appears on both these lists, https://owncloud.com/  Using Linode or other possible commercial hosters to host your own semi-private cloud solution or mirroring your local system to them is another thing we are exploring. Linode https://www.linode.com/ , AWS  https://aws.amazon.com/ Amazon Web Services and some other possible commercial cloud providers as mirroring options for our locally seated/seeded solutions.

https://storj.io/  Is another one we’re reviewing.

https://www.cyberciti.biz/cloud-computing/7-awesome-open-source-cloud-storage-software-for-your-privacy-and-security/ is another article with a selection of options that are encrypted and self-hosted.

Currently getting mixed reviews from what I am seeing in my research.

This may be a suitable starting point, from what I am seeing of their product specifications and options.
