  • Impostare l'host fittizio di backup
sudoedit /etc/backuppc/hosts

archive         0               backuppc        miaemail@dominio.dom
  • Creare il file di configurazione
cat | sudo tee /etc/backuppc/archive.pl >/dev/null <<'EOFile'

$Conf{XferMethod} = 'archive';
$Conf{ClientTimeout} = 172800 ;
$Conf{ArchiveComp} = '/usr/bin/pigz';
$Conf{ArchiveCompExt} = '.gz';
$Conf{ArchiveSplit} = '0';
#$Conf{ArchiveSplit} = '1999M';
$Conf{ArchiveDest} = '/media/archive';
$Conf{ArchivePostUserCmd} = '/usr/local/bin/ArchivePostUserCmd $client $xferOK $host $HostList $BackupList $moreUsers'
EOFile
  • Creare lo script di notifica
cat | sudo tee /usr/local/bin/ArchivePostUserCmd </dev/null <<'EOFReal'
#!/bin/bash
RECIPIENTS="user1@example.com,user2@example.com"

client="$1"
xferOK="$2"
host="$3"
hostList="$4"
BackupList="$5"
moreUsers="$6"

if [ "$xferOK" -eq 1 ]
then
        SUBJECT="Archiving Succesful on $client"
        MSG=$(cat <<EOFile
The Archiving of $client was succesfull.

Parameters are:
client="$1"
xferOK="$2"
host="$3"
hostList="$4"
BackupList="$5"
moreUsers="$6"
EOFile
)

else
        SUBJECT="Archiving UNSUCCESSFUL on $client"

        MSG=$(cat <<EOFile
The Archiving of $client was UNSUCCESSFUL.

Parameters are:
client="$1"
xferOK="$2"
host="$3"
hostList="$4"
BackupList="$5"
moreUsers="$6"
EOFile
)
fi

echo -e "echo $MSG  mail -s ${SUBJECT} ${RECIPIENTS}
/usr/bin/logger -t BackupPcArchive "${SUBJECT} - ${MSG}"
echo -e $MSG | mail -s "${SUBJECT}" ${RECIPIENTS}
echo -e $MSG | mail -s "${SUBJECT}" ${RECIPIENTS}
/usr/bin/logger -t BackupPcArchive "Umounting device."
sudo umount /dev/sdd1
sudo rmdir /media/archive
EOFReal
  • Impostare i destinatari della notifica:
sudoedit /usr/local/bin/ArchivePostUserCmd
  • Rendere lo script eseguibile
sudo chmod +x /usr/local/bin/ArchivePostUserCmd
  • Riavviare backuppc
sudo invoke-rc.d backuppc restart
  • Creare la cartella:
sudo mkdir -p /var/lib/backuppc/pc/archive; sudo chown backuppc:www-data /var/lib/backuppc/pc/archive; sudo chmod o-rwx /var/lib/backuppc/pc/archive
  • Da interfaccia web, selezionare l'host archive e fare l'archiviazione, oppure lanciarla da command line:
sudo -u backuppc /usr/share/backuppc/bin/BackupPC_archiveStart  archive backuppc host_da_archiviare

Fix per Debian Squeeze

  • Con Debian Squeeze, lo script per sottomettere l'archiviazione non permette di comprimere e splittare.
  • Copiare lo script:
sudo cp  /usr/share/backuppc/bin/BackupPC_archiveStart /usr/local/sbin/BackupPC_archiveStart.custom
  • Modificare come segue:
vi /tmp/patch1.diff

cd /usr/local/sbin
patch --dry-run < /tmp/patch1.diff
  • Inserire i parametri nel file di config:
sudoedit /etc/backuppc/archive.pl 

$Conf{XferMethod} = 'archive';
$Conf{ClientTimeout} = 172800 ;
$Conf{ArchiveComp} = '/usr/bin/pigz';
$Conf{ArchiveCompExt} = '.gz';
$Conf{ArchiveSplit} = '0';
#$Conf{ArchiveSplit} = '1999M';
$Conf{ArchiveDest} = '/media/archive';
$Conf{ArchivePostUserCmd} = '/usr/local/bin/ArchivePostUserCmd $client $xferOK $
host $HostList $BackupList $moreUsers';
  • Sottomettere il job con questo script, che provvede a conservare solo gli ultimi 4 backup di ogni host:
sudoedit /usr/local/sbin/BackupPcArchive

#!/bin/bash
/usr/bin/logger -t BackupPcArchive "Udev parameters: ACTION=${ACTION} - DEVICE=${DEVICE}"
/usr/bin/logger -t BackupPcArchive "Starting archiving ..."
/usr/bin/logger -t BackupPcArchive "Creating mount point ..."
sudo mkdir -p /media/archive
/usr/bin/logger -t BackupPcArchive "Mounting device ..."
sudo /bin/umount /media/archive > /dev/null 2>&1
sudo mount /dev/sdd1 /media/archive > /dev/null
# Erase oldest files
cd /media/archive
HOSTS2BACKUP="firemar marsrv01 marstor01"
for BKPHOST in $HOSTS2BACKUP
do
        FILES2DELETE=$( (/bin/ls -1v ${BKPHOST}* 2>/dev/null | /usr/bin/tail -n 4;/bin/ls -1 ${BKPHOST}* 2>/dev/null)| /usr/bin/sort | /usr/bin/uniq -u )
        if [ -n "$FILES2DELETE" ]
        then
                /usr/bin/logger -t BackupPcArchive "Deleting files '$FILES2DELETE'"
                /bin/rm -f $FILES2DELETE
        fi
done
# These scripts forks in the background
/usr/bin/logger -t BackupPcArchive "Queueing archiving of ${HOSTS2BACKUP} ... "
#/usr/share/backuppc/bin/BackupPC_archiveStart  archive backuppc marsrv01 firemar marstor01
/usr/local/sbin/BackupPC_archiveStart.custom  archive backuppc ${HOSTS2BACKUP}
/usr/bin/logger -t BackupPcArchive "Jobs queued."
# umount and remove mountpint is done in /usr/local/bin/ArchivePostUserCmd
