BackupPC 3.3 est disponible sur les dépôts officiel de Debian:

# apt install backuppc

Il faut configurer Apache2, donc commencer par :

# rm /etc/apache2/sites-enabled/*

Il faut ensuite créer un VirtualHost d'Apache2 dans /etc/apache2/sites-available comme ceci :

backuppc.conf

<VirtualHost *:80>
    DocumentRoot /usr/share/backuppc/cgi-bin
    Alias /backuppc /usr/share/backuppc/cgi-bin/
    <Directory /usr/share/backuppc/cgi-bin/>
        AllowOverride None
        Allow from all
 
        Options ExecCGI FollowSymlinks
        AddHandler cgi-script .cgi
        DirectoryIndex index.cgi
 
        AuthUserFile /etc/backuppc/htpasswd
        AuthType basic
        AuthName "BackupPC admin"
        require valid-user
    </Directory>
</VirtualHost>

Puis de l'activer :

# a2ensite backuppc.conf
# systemctl reload apache2

On va aussi définir un mot de passe a l'utilisateur backuppc en rentrant la commande :

# htpasswd /etc/backuppc/htpasswd backuppc

Il faut ensuite créer la clés SSH de l'utilisateur backuppc en lançant les commandes :

# sudo -i -u backuppc
# ssh-keygen -t rsa -b 4096
# exit

Attention à ne pas mettre de Passphrase a la clé.

Pour changer l'emplacement de travail de BackupPC (en l’occurrence des backups), il faut d'abord copier le dossier de travail dans la nouvelle destination :

# rsync -aAXv /var/lib/backuppc /path/to/dest/

puis de modifier les champs suivants dans la fichier /etc/backuppc/config.pl :

$Conf{TopDir}      = '/path/to/dest/';
$Conf{LogDir}      = '/path/to/dest/log';

Puis relancer le service

# systemctl restart backuppc

Attention, cela nécessite de compiler le packet. J'ai donc réalisé ce script pour le faire a votre place :)

backuppc4-setup.sh

#!/bin/bash

	echo -e "usage : ./backuppc4-setup.sh --install (or upgrade from backuppc 3)\nor: ./backuppc4-setup.sh --upgrade\nMUST BE RUN AS ROOT"
