Backup + Bacula + 備份於 DVD 光碟

必需重新編譯 dvd+rw-tools，讓它支援 bacula
wget http://fy.chalmers.se/~appro/linux/DVD+RW/tools/dvd+rw-tools-5.21.4.10.8.tar.gz
tar zxvf dvd+rw-tools-5.21.4.10.8.tar.gz
cd dvd+rw-tools-5.21.4.10.8.
patch -p1 < ../bacula-1.38.11/patches/dvd+rw-tools-5.21.4.10.8.bacula.patch

編譯
make

之後把產生的執行檔覆蓋於 /usr/bin目錄

測試
/usr/local/bacula/etc/dvd-handler /dev/dvd test

設定 DVD設備

vi /usr/local/bacula/etc/bacula-sd.conf

# 加入 DVD device設定
#
# A DVD device
#
Device {
   Name = "DVD-Writer"
   Media Type = DVD
   Archive Device = /dev/hdd
# lets Bacula label unlabeled media
   LabelMedia = yes;
   Random Access = Yes;
# when device opened, read it
   AutomaticMount = yes;
   RemovableMedia = yes;
   AlwaysOpen = yes;
   #MaximumPartSize = 800M;
   RequiresMount = yes;
   MountPoint = /media/dvd;
# %a = Archive device name
# %m = mount point
   MountCommand = "/bin/mount -t iso9660 -o ro %a %m";
   UnmountCommand = "/bin/umount %m";
   SpoolDirectory = /usr/local/bacula/backup;
# %e = erase (set if cannot mount and first part)
# %v = last part name (i.e. filename)
   WritePartCommand = "/usr/local/bacula/etc/dvd-handler %a write %e %v"
   FreeSpaceCommand = "/usr/local/bacula/etc/dvd-handler %a free"
}

mkdir /usr/local/bacula/backup

mkdir /media/dvd

vi /usr/local/bacula/etc/bacula-dir.conf

## [ cross ] END

   /usr/local/bacula/etc/bacula restart

把 bac-dvd-cross作個 Label
/usr/local/bacula/etc/bconsole
*label
      -> x: bac-dvd-cross

接下來就直接跑個 Job吧

備份之前的準備動作，執行
/usr/local/bacula/etc/dvd-handler /dev/hdd prepare

附註:
指令抹除光碟片
快速
dd if=/dev/zero bs=1025 count=512 | growisofs -Z /dev/hdd=/dev/fd/0

完整
growisofs -Z /dev/hdd=/dev/zero

燒錄
growisofs -Z /dev/hdd FILENAME

續燒
growisofs -M /dev/hdd FILENAME
