Bacula for Linux

Detailed guide for setting up Bacula backup on your Linux server.

---

Log in to your server via SSH. To install the packages required for Bacula to work, you need to log in as root.

Run this command to install the Bacula software (note that the exact command may vary depending on which Linux distribution you are using):

Command

apt-get install bacula-client

Open the file /etc/bacula/bacula-fd.conf and replace the existing content with the configuration shown below.

If your server is placed in Stockholm:

/etc/bacula/bacula-fd.conf

Director {
        Name = bacula02-fbg-fd
        Password = "YourPasswordGoesHere"
}  
FileDaemon {
        Name = ds*****
        FDport = 9102
        FDAddress = 0.0.0.0
        WorkingDirectory = /var/lib/bacula
        Pid Directory = /var/run/bacula
        Maximum Concurrent Jobs = 20
}  
Director {
        Name = bacula02-fbg-mon
        Password = "LkRjyq760wGbAXeah4ofS55bG41q4p"
        Monitor = yes
}  
Messages {
        Name = "Standard"
        director = bacula02-fbg-dir = all, !skipped
}

If your server is placed in Falkenberg:

/etc/bacula/bacula-fd.conf

Director {
        Name = bacula06-vbdc-dir
        Password = "YourPasswordGoesHere"
}
FileDaemon {
        Name = ds*****
        FDport = 9102
        FDAddress = 0.0.0.0
        WorkingDirectory = /var/lib/bacula
        Pid Directory = /var/run/bacula
        Maximum Concurrent Jobs = 20
}
Director {
        Name = bacula06-vbdc-mon
        Password = "gRTYk9qEJebexvA4BtguTCQ26kmo4J9ajY"
        Monitor = yes
}
Messages {
        Name = Standard
        director = bacula06-vbdc-dir = all, !skipped
}

Replace YourPasswordGoesHere with a password you choose. Also, change ds****-fd to your server’s name, e.g., ds1234-fd.

Bacula requires the directories /var/lib/bacula and /var/run/bacula to exist (unless you have specified different paths in your configuration).

If they were not created during installation, create them with:

Command

mkdir -p /var/lib/bacula /var/run/bacula

Then, restart Bacula by using the command:

Command

/etc/init.d/bacula-client restart

Enter your password in the form at https://secrets.glesys.com/ and send the link together with a list of the directories you want to back up to [email protected]. Preferably in the format shown below:

Example format for email

- name: 'ds****'
  address: '1.2.3.4'
  password: 'YourPasswordGoesHere'
  files: ['/root', '/etc', '/usr/local', '/var/spool/cron', '/home']
  excludes: ['/home/mapp1', '/home/mapp2']
  runbeforejob: '/usr/local/bin/mysqlbackup.sh root NOPASS /root/mysqldumps'
  storage: 150
  email: [email protected]än

Keep in mind that if you are using a firewall to protect your server, you need to allow traffic from Bacula; the iptables rules are listed below:

iptables rules to allow traffic from Bacula

iptables -A INPUT -p TCP --dport 9102 -s 195.20.207.32/28 -j ACCEPT # Bacula_VBDC
iptables -A INPUT -p TCP --dport 9102 -s 195.238.77.0/28 -j ACCEPT # Bacula_FBG
iptables -A OUTPUT -p TCP --dport 9103 -d 195.20.207.32/28 -j ACCEPT # Bacula_VBDC
iptables -A OUTPUT -p TCP --dport 9103 -d 195.238.77.0/28 -j ACCEPT # Bacula_FBG
iptables -A INPUT -p TCP --sport 9103 -m state --state ESTABLISHED -j ACCEPT # Bacula

MySQL backup with Bacula

Backups with Bacula operate at the file level and read data directly from disk. For MySQL, it isn’t always guaranteed that all data has been flushed to disk, and restoring MySQL’s raw data files doesn’t always work. Therefore, we recommend dumping the database to SQL files at regular intervals.

Example script for dumping data in MySQL:

/root/mysqlbackup.sh

#!/bin/sh
if [ -z $3 ]; then
    echo "Wrong syntax..."
    echo "use: $0 <mysql_root> <mysql_password> <dump_dir>"
    exit
fi
echo Dumping MySQL database to $3.
umask 077
rm $3/*
mkdir $3 &>/dev/null
cd $3
for i in `echo "SHOW DATABASES" |/usr/bin/mysql -s -u $1 -p$2`; do
     /usr/bin/mysqldump --single-transaction -f -u $1 -p$2 $i >$i.sql
    if [ $? -ne 0 ] ; then
            echo ERROR: Fail when dumping $i
    fi
done
du -sh $3
echo Databasedump done

This script could be scheduled in crontab with the following entry to save the database to a file every day at 22:00.

Example crontab entry

0 22 * * * /root/mysqlbackup.sh root YOUR_DATABASE_PASSWORD /root/mysqldumps
