Backup locale con BackuPc

Si usa il metodo Tar locale, eseguito come root tramite sudo.

• Creare il file di configurazione:

sudoedit /etc/backuppc/myclient.pl

# Local server backup of / as user backuppc
#
$Conf{XferMethod} = 'tar';

$Conf{TarShareName} = [
        '/',
];

$Conf{TarClientCmd} = '/usr/bin/env LC_ALL=C /usr/bin/sudo $tarPath --one-file-system -c -v -f - -C $shareName'
                                                . ' --totals';
# Please note the use of sudo and --one-file-system

# remove extra shell escapes ($fileList+ etc.) that are
# needed for remote backups but may break local ones
$Conf{TarFullArgs} = '$fileList';
$Conf{TarIncrArgs} = '--newer=$incrDate $fileList';
 
# Minimum period in days between full and incremental backups:
# 1 Full alla settimana
$Conf{FullPeriod} = 6.97;
# 2 o almeno un incr al giorno
$Conf{IncrPeriod} = 0.49;

# Number of full and incremental backups to keep:
$Conf{FullKeepCnt} = 12;
$Conf{IncrKeepCnt} = 93;

# Level of verbosity in Xfer log files:
$Conf{XferLogLevel} = 1;

# Compression level to use on files. 0 means no compression. See notes
# in main config file before changing after backups have already been done.
$Conf{CompressLevel} = 9;
$Conf{BackupFilesExclude} = [
        '/cdrom',
        '/dev',
        '/floppy',
        '/lost+found',
        '/mnt',
        '/proc',
        '/sys',
        '/var/lib/backuppc/cpool',
        '/var/lib/backuppc/log',
        '/var/lib/backuppc/pc',
        '/var/lib/backuppc/poll',
        '/var/lib/backuppc/trash',
        '/var/spool/squid',
        '/var/spool/squid3',
];

• Aggiungere l'host con il nome:

echo "myclient    0       backup@example.com      backuppc" | sudo tee /etc/backuppc/hosts > /dev/null

• Sistemare le permission

sudo chown backuppc:www-data myclient.pl
sudo chmod 0640 myclient.pl

• Riavviare backuppc

sudo invoke-rc.d backuppc restart

• Abilitare l'utente backuppc ad eseguire sudo senza password

sudo visudo

...
backuppc ALL = NOPASSWD: /bin/tar
...

• Testare un backup locale

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