Backup

Ubuntu nutzt Deja-dup ¹⁾, das wiederum auf duplicity basiert.

Duplicity-Backup-script von Hetzner: http://wiki.hetzner.de/index.php/Duplicity_Script

Zugänglich via Systemeinstellungen→Sicherung

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

cat duplicity.sh 
#!/bin/sh
#
# Script created on 17-6-2008
#
# This script was created to make Duplicity backups.
# Full backups are made on the 1st day of each month.
# Then incremental backups are made on the other days.
#
# Quielle: http://wiki.hetzner.de/index.php/Duplicity_Script

# Loading the day of the month in a variable.
date=`date +%d`

# call with parameter 'full' for a full backp

servername="ftp://[xxx].your-backup.de"

# Setting the pass phrase to encrypt the backup files. Will use symmetrical keys in this case.
PASSPHRASE='[password]'
export PASSPHRASE

# Setting the password for the FTP account that the
# backup files will be transferred to.
FTP_PASSWORD='[ftp-pw]'
export FTP_PASSWORD

# Check to see if we're at the first of the month.
# If we are on the 1st day of the month, then run
# a full backup. If not, then run an incremental
# backup.
if [ $date = 01 ] || [ "$1" = full ]
