Cyphertite may also be of interest: https://www.cyphertite.com/ https://www.cyphertite.com/ Client-side encryption and deduplication, with source code. 8GB free, $10/mo for personal unlimited use, 10c/GB/month for business/enterprise. My main reservations are they seem to be based in one datacenter, and don't seem to have support for multiple keyfiles with separate read/write/delete/machine restrictions. Also not in FreeBSD ports :P
