Bacula basic configuration

Description

Bacula is an enterprise-grade backup utility. This HowTo explains how to set up bacula on Fedora while respecting Fedora's configuration way.

Applicable to Fedora Versions

• Fedora 12

Requirements

Bacula supports a few database backends, so, you will need to choose one. On this document, I will choose the mysql backend. Clients do not need a database backend.

Also, you will need to decide which console(s) you want and configure them. I will choose the commandline console.

Storage, database and director could be distributed but, in this case, everything will be managed on the same server.

Server requirements

• bacula-common
• bacula-console
• bacula-director-common
• bacula-director-mysql
• bacula-sysconfdir
• bacula-storage-common
• bacula-storage-mysql
• mysql-server

Client's requirements

• bacula-client

Storage, database and director could be distributed but, in this case, everything will be managed on the same server.

Doing the Work

Configuring the server

• Install mysql-server:

su -c 'yum install mysql-server'

• Install the relevant bacula packages

su -c 'yum install bacula-common \
bacula-console bacula-director-common \
bacula-director-mysql bacula-storage-common \
bacula-storage-mysql bacula-sysconfdir'

• Start the mysql server

su -c 'service mysql start'

• Grant privileges to the bacula user

su -c '/usr/libexec/bacula/grant_mysql_privileges'

• Create the database

su -c '/usr/libexec/bacula/create_mysql_database'

• Create the necessary tables

su -c '/usr/libexec/bacula/make_mysql_tables'

• Add a strong password to the bacula user

su -c 'mysql -u root'
UPDATE mysql.user SET Password=PASSWORD(',Somes7r0nGp4$5w_rD--') WHERE User='bacula';
FLUSH PRIVILEGES;

• Set /etc/bacula/bacula-dir passwords

• Configure bacula's mysql user on the /etc/bacula/bacula-dir.conf

Catalog {
  Name = MyCatalog
  dbname = "bacula"; dbuser = "bacula"; dbpassword = ""
}

to:

Catalog {
  Name = MyCatalog
  dbname = "bacula"; dbuser = "bacula"; dbpassword = ",Somes7r0nGp4$5w_rD--"
}

• Set /etc/bacula/bacula-fd passwords

• Set /etc/bacula/bacula-sd passwords

+ Open up the relevant iptables port

su -c 'iptables -A INPUT -m state --state NEW -m tcp \
-p tcp --dport 9101 -j ACCEPT'
su -c 'iptables -A INPUT -m state --state NEW -m tcp \
-p tcp --dport 9103 -j ACCEPT'

• Start the storage and dir services

su -c 'service start bacula-sd'
su -c 'service start bacula-dir'
su -c 'service start bacula-fd'

Since you need to generate quite a few secure passwords, I recommend using apg; specifically: apg -M LCN -m 32 -x 32. This tool can be installed from the repositories.

Configuring the clients

• Install the bacula client

su -c 'yum install bacula-client'

• Configure the client's and monitor's names, addresses and passwords. These ones need to be present in the server configuration so, keep track of the passwords and names.

# Default  Bacula File Daemon Configuration file
#
#  For Bacula release 3.0.3 (18 October 2009) -- redhat 
#
# There is not much to change here except perhaps the
# File daemon Name to
#

#
# List Directors who are permitted to contact this File daemon
#
Director {
  Name = bacula-dir
  Password = "fd_password" # change to a nice and strong password
}

#
# Restricted Director, used by tray-monitor to get the
#   status of the file daemon
#
Director {
  Name = bacula-mon
  Password = "mon_fd_password" # change to a nice and strong password
  Monitor = yes
}

#
# "Global" File daemon configuration specifications
#
FileDaemon {                          # this is me
  Name = bacula-fd
  FDport = 9102                  # where we listen for the director
  WorkingDirectory = /var/spool/bacula
  Pid Directory = /var/run
  Maximum Concurrent Jobs = 20
}

# Send all messages except skipped files back to Director
Messages {
  Name = Standard
  director = bacula-dir = all, !skipped, !restored
}

+ Open up the relevant firewall port; in this case, 9102

su -c 'iptables -A INPUT -m state --state NEW -m tcp \
-p tcp --dport 9102 -j ACCEPT'

Disclaimer

I haven't had the opportunity to test this HowTo since I lack of a networked PC to do it, so you may run into problems, if you do, come to #fedora on irc.freenode.net or leave me messages so I know what's up. Feel free to propose changes and stuff.
