Have you looked into using mdconfig(8) to make a vnode (ie: file) backed
md disk, and then encrypting with geli(8)? 

This would be generated on your trusted local box, transferred encrypted
to your backup box, where it can't be examined without your key, but
with your key it could be mounted simply enough. 

You wouldn't be able to take incremental snapshots easily - unless
perhaps you generated a list of modified/added files and used those
files as your incremental snapshot. This may/may not be viable,
depending on the size of your data set.
