I have been troubleshooting how the backup for a system with total disk usage 
of 9GB could produce a 24 GB backup.

What I found is that apparently, bacula backs up the same file two or sometimes 
three times within a job. On this system, all data is contained in a single 
file system. The file set contains root, as well as several subdirectories. 
Apparently, the problem occurs for directories that are named explicitly, and 
also included through a parent. For instance, /var/log/messages got backed up 
three times with the file set listed below - probably because it is included 
through /, /var and /var/log.

Bacula-fd: Bacula 2.4.2 (on CentOS 5.4)
Bacula-dir (and bacula-sd): Bacula 3.0.3 (on OpenSUSE 11.2)

Is that because of an incompatibility between 2.4 and 3.0, or am I doing 
something else wrong?


FileSet {
  Name = "Linux Full Set"
  Include {
    Options {
      signature = MD5
    }
    File = /
    File = /boot
    File = /home
    File = /srv
    File = /usr
    File = /var
    File = /var/log
    File = /var/lib/bacula
  }
  Exclude {
    File = /proc
    File = /dev
    File = /sys
    File = /tmp
    File = /.journal
    File = /.fsck
    File = /srv/installimage
    File = /var/lock
    File = /var/run
    File = /var/tmp
    File = /var/cache
    File = /var/spool/postfix/public
    File = /var/spool/amavis/virusmails
    File = /var/spool/postfix/private
    File = /var/lib/mysql
    File = /var/lib/dhcp/dev/log
    File = /var/lib/php5
    File = /var/lib/named/dev/log
    File = /var/lib/samba/winbindd_privileged/pipe
    File = /var/lib/zypp/cache
    File = /var/lib/zmd
    File = /var/lib/ntp
    File = /var/lib/logrotate.status
    File = /var/spool/cron/lastrun
    File = /var/log/zmd-*
    File = /var/log/ntp
    File = /var/log/httpd/error.*
    File = /virtual
  }
}
