New to ecryptfs, what do I need to backup?
I am a new ecryptfs user and I am wondering what I need to backup if I setup an encrypted folder pair by hand.
For example, I encrypt the /srv directory on top of itself using sudo mount -t ecryptfs -o ecryptfs_
I am now interested in what I have to remember. Obviously my passphrase that I entered at first. Do I also need to remember (write down) the FNEK signature?
What about the file /root/.
I have moved the folder to another VBox and tried it again and it seemed that my passphrase was sufficient. Is the FNEK signature generated from the passphrase + my username or so?
Also: What parts should I not backup online? The Ubuntu tutorials mention a /home/.ecryptfs (when encrypting the home folder = not my case) or similar that needs to be remembered but shouldn't be stored online in order to avoid weakening the encryption. I couldn't find anything similar after running the above command, should I?
I have tried to find this, but the tutorials didn't seem to mention it. I really need to know this before starting backups of my encrypted folder though, obviously.
I hope you understand.
