Spideroak?
I have used Spideroak in the past for their backup services but had to go with another service because their software wasn't ready for prime time. Updates to their software would break the software and then I would have to uninstall the new version and reinstall the older version. It would miss files in some folders, especially files that were added to a folder. It was also frustrating to do tech support via email with a long delay between submission of the email and a response. There was a lot to like about Spideroak but for my needs it just didn't work.
