That's pretty much what I want, but it requires you to have as much free space as the thing you want to back up.
What I wanted to do was mount EncFS in reverse mode (so it gets plain files and creates an encrypted virtual volume) and rdiff-backup that to a remote host, which works very well. However, the problem is that, when your directories are disparate, you can't easily make them appear as one directory, so, to back up 5 locations you'd have to do this 5 times.
I can fake it using AUFS or similar, but it's too large a dependency. Someone wrote an EncFS patch to let it follow symlinks in reverse mode (https://code.google.com/p/encfs/issues/detail?id=147), which would solve the problem, but I don't think EncFS is maintained any more.

I have a friend that backs up his photos to my computer using a combination of ecryptfs, rdiff-backup, and rsync. It goes something like this:
