Installazione e Configurazione di BackupPc

Attenzione questo articolo è ancora incompleto. Sentiti libero di contribuire cliccando sul tasto edit.

Installazione

sudo apt-get install backuppc rsync libfile-rsyncp-perl par2 smbfs apache2

Cambiare la password di default per l'accesso a backuppc:

sudo htpasswd /etc/backuppc/htpasswd backuppc

Se installa anche apache, rimuoverlo:

sudo apt-get remove --purge apache apache-common
sudo rm -rf /etc/apache

Installare il file di configurazione di backuppc in apache2

cd /etc/apache2/sites-available/
sudo ln -s /etc/backuppc/apache.conf backuppc
sudo touch /etc/apache2/httpd.conf

Attivare la configurazione

sudo a2ensite backuppc

Impostare l'autostart di apache2

cat | sudo tee /etc/default/apache2 > /dev/null <<EOFile
# 0 = start on boot; 1 = don't start on boot
NO_START=0
EOFile

Riavviare apache 2

sudo /etc/init.d/apache2 restart

Testare apache2

• Vedere se mostra "It worls !" http://fireber

Testare backuppc

• Loggarsi con backuppc/password_impostata http://fireber/backuppc (attivare javascript !!!)
• Lanciare un backup di localhost dall'interfaccia

Configurazione BackuPC

Cambiare i seguenti parametri:

sudoedit /etc/backuppc/config.pl

$Conf{Language} = 'it';

Configurazione del backup di un host via ssh

Inserire il nome del pc da backuppare:

echo berserver   1       backuppc | sudo tee -a /etc/backuppc/hosts > /dev/null

Creare il file di configurazione scegliendo cosa backuppare:

cat | sudo tee /etc/backuppc/berserver.pl < /dev/null <<'EOFile'

sudo chown backuppc\: /etc/backuppc/berserver.pl
sudo chmod o= /etc/backuppc/berserver.pl

Riavviare backuppc

sudo /etc/init.d/backupp restart

Controllare via web che l'host sia presente

Configurazione dell'accesso ssh sulla macchina da backuppare

Creare la chiave privata di backuppc sul server backuppc

sudo su backuppc
ssh-keygen -t rsa

Generating public/private rsa key pair.
Enter file in which to save the key (/var/lib/backuppc/.ssh/id_rsa): <-- <ENTER>
Created directory '/var/lib/backuppc/.ssh'.
Enter passphrase (empty for no passphrase): <-- <ENTER>
Enter same passphrase again: <-- <ENTER>
Your identification has been saved in /var/lib/backuppc/.ssh/id_rsa.
Your public key has been saved in /var/lib/backuppc/.ssh/id_rsa.pub.
The key fingerprint is:
74:20:65:73:47:1c:cb:ba:5d:9b:5d:56:cf:91:1a:1a backuppc@server1.example.com

Copiare /var/lib/backuppc/.ssh/id_rsa.pub sul server da backuppare

sudo cp /var/lib/backuppc/.ssh/id_rsa.pub /tmp
scp /tmp/id_rsa.pub berserver:/tmp

Sul server da backuppare, aggiungere questa chiave per l'utente

$ cat /tmp/id_rsa.pub | sudo tee -a /root/.ssh/authorized_keys

Controllare che l'utente backuppc possa loggarsi via ssh senza password su server da backuppare

mnt.vvngrl@fireber:/tmp$ sudo -u backuppc ssh root@berserver

Configurazione dell'accesso SAMBA sulla macchina da backuppare

• Il tutto vale per Windows XP PROFESSIONAL. Per XP Home non va.
• Assicurarsi di poter accedere con utente e password alle condivisoni
• Se si usano C$ e D$, assicurarsi di aver disabilitato la "Condivisione files semplice" da "Strumenti - Opzioni Cartella - Visulizzazione - Impostazioni avanzate" di Explorer.

Lanciare un backup di prova da commandline:

sudo -u backuppc /usr/share/backuppc/bin/BackupPC_dump -v -f rosnotcri
