Creating Encrypted FTP Backups With duplicity And duply On Debian Squeeze

[biggdog]

I have followed you instructions and have had no reson to think I had a problem until now.
I had to redo my mail server and I now want to restor my backups made on my NAS unit but I am not able to do so.

duply exampleuser restore /var/vmail

--- Start running command RESTORE at 17:35:39.360 ---
NcFTP version is 3.2.4
Restore destination directory /var/vmail/biggdog.biz already exists.
Will not overwrite.
17:35:39.469 Task 'RESTORE' failed with exit code '11'.
--- Finished state FAILED 'code 11' at 17:35:39.469 - Runtime 00:00:00.108 ---

Now it seems I may have done these backups for nothing.

Please help.

I may have found the issue. I need to know how to put back the original key into the new system. Will that work???
