So first of all Thank You for your help.

I think that there is no 100% solution to avoid telling passwordphrases to 
Because you must tell duplicity e.g the password for FTP connection, a intruder 
could also
login to your FTP remote Server and delete all backup archives.

Make it over a shell script would be best, but if the attacker gets root 
permission on the Server 
... it´s to late anyway.

Backing up per hand and not with the help of a cron job isn´t that convinient I 
think it should be.

The PASSPHRASE="***" option is not described in the manual, so I couldn´t find 

Thanks to all of you for help!
