I would like to use Encfs to encrypt a copy of / for a backup by using the reverse option and then running my backup tool on the virtual, encrypted filesystem. Whenever I back up through other tools (rsync for example), they have an option to not cross filesystem boundaries.

Is there an equivalent option in Encfs? Or would such attributes pass through to the encrypted version, and I should just run my backup tool with the one filesystem option?

The question above was answered by @Azendale. So this here cant be a dupe. – Takkat Sep 30 '12 at 15:35
@January I already know about the reverse option. (I found that question and answered it when I was writing my question.) My question as about tweaking the behavior of the reverse option. – Azendale Sep 30 '12 at 20:07
Sorry, I retract my statement. – January Oct 1 '12 at 5:07

I have been looking for an answer to the same question, and I am afraid the answer is nope, this is not (yet) possible with encfs.

The closest I found was this bug report:

encfsctl encode is also capable of encrypting single files, but that's an overkill for excluding other filesystems (or even single files).
