Need default duplicity GnuPG passphrase for manual restore

[on4aa]

Intro: How I got into problems:
Being a bubba2 newbie with an additional Bubba Storage drive, I made the mistake of including the entirety of the "storage" directory (where pictures and music are stored by default) to my weekly full backup schedule without any encryption.

What I did not realise, was that the external additional Bubba Storage drive is also happens to be mounted under the "storage" directory, in a subdirectory of the "extern" directory. So week after week, I was backing up also all my backups until no place was left on the 1TB Bubba Storage drive.

I would not have noticed anything if it were not for accidentally deleting two IMAP e-mail folders (possibly because of poor interaction of Evolution with dovecot), that I now needed my backup.

What I need:
Although the web interface does not allow any restore, I have noticed via ssh that a couple of backup manifest files mention the Mail folders I am after. Running duplicity restore from the shell, I receive the following prompt, although I never specified any encryption password for my backups:

Code: Select all

Warning, found incomplete backup sets, probably left from aborted session
GnuPG passphrase: 

I tried my user, admin and root passwords without success. My question: What GnuPG passphrase does backup use with duplicity by default ???

Should you need to run duplicity manually at the command line in attempt to recover a partial backup etc., you need to become su in a ssh. The default password for su is "excito" and so is the GnuPG passphrase.
