Beim 1. Backup fragt einen das Programm, ob man verschlüsseln will… (und arbeitet dabei mit der .ICEauthority)

neues Script: ²⁾

#
# Simple script for creating backups with Duplicity.
# Full backups are made on the 1st day of each month or with the 'full' option.
# Incremental backups are made on any other days.

# USAGE: backup.sh [full]

DATE=`date +%d`

# Set protocol (use scp for sftp and ftp for FTP, see manpage for more)

# set user and hostname of backup account
BUSER='u10000'
BHOST='u10000.your-backup.de'

# Setting the password for the Backup account that the
# backup files will be transferred to.
# for sftp a public key can be used, see:
