rsync.net is awesome. You get a Linux filesystem you can access via SSH. Many tools support it (like git-annex), and since it's ssh-able, you can script anything that doesn't work out of the box.
They also have optional replication, and you can choose the location of both of the servers that host your files. Great support from actual engineers, used by huge companies for their offsite backups, and never been breached (to my knowledge).

EDIT: their features page is a good read. https://www.rsync.net/cloudstorage.html
