My rdiff-backup main repo is in a encfs filesystem.  Encfs may not be
a fully secure as other choices (I don't know), but it does allow
rsync of the encrypted data to a remote site.  (I do that).

I have done test restores to a third machine and unencrypted my data
via encfs on that machine.

So if encfs is secure enough for you, it works fine with rdiff-backup.

fyi: what is a "spare file"?
