== Concepts and definitions ==
=== Basic description of bacula ===
The basic system comprises three components: the director, the file daemon and the storage daemon. To take them in reverse order, the storage daemon takes data from the file daemon and stores it wherever directed. The file daemon gets the data (files) to be backed up and passes it to the storage daemon. The director then does the rest of the work; that is, defines the task to be performed and the schedule for them to be performed. The basic unit for a backup is the job. This describes what is to be backed-up, when it is to occur and where the data is to be stored.
=== Some definitions ===
'''Volume''' - basic unit of storage, e.g. a tape, a dvd, a file on a hard drive.
'''Pool''' - a collection of volumes, usually used for the same purpose.
'''FileSet''' - the files to be backed up.
'''Job''' - the overall definition of the work to be performed.
'''Catalogue''' - storage area for information about all jobs that have run.
'''Full Backu'''p - every file in the FileSet is to be copied.
'''Incremental''' - a backup that contains all files that have changed since the last full, differential or incremental backup.
'''Differential''' - a backup that contains all files that have changed since the last full backup.
=== Configuration files ===
To configure each component there is a .conf file in /etc/bacula. Each file defines the interconnectivity with the others, so you need make sure all the passwords agree one with another (you'll see what I mean when you look at the details). bacula-sd.conf defines the storage devices that you want to use, and bacula-fd.conf merely defines itself. The main work is done in bacula-dir.conf, which sets up the everything else. The configuration files are used to define those components that are to be run automatically: ad-hoc jobs can be run through the console.
=== Workflow ===
The method of operation for bacula is that the requisite data is stored on Volumes, which are essentially container files stored on differing media. These volumes are organized into Pools in a many to one relationship. Filesets are the collections of files that you want to backup using the same volumes. The timing for preforming backups are defined using Schedules, and all these are tied together as jobs, which define the pool (and hence volumes) to be used to create backups of the files defined within a fileset at a particular schedule.

=== Using MySQL backend in Fedora 17+ ===
Starting in Fedora 17, Bacula RPMs from the official repository are shipped with postgresql support by default. To use the MySQL backend, as shown in the article, do the following:
* Stop Bacula services if they are running:
<pre>
su -c 'service bacula-dir stop'
su -c 'service bacula-fd stop'
su -c 'service baucla-sd stop'
</pre>
 
* Change the "libbaccats" (the catalogue library) symlink to the real library. To change to a different backend, issue the following command:
 
<pre>su -c 'alternatives --config libbaccats.so'</pre>
 
There are 3 programs which provide 'libbaccats.so'. You'll see something like the following:
 
<pre>
  Selection    Command
-----------------------------------------------
  1          /usr/lib64/libbaccats-mysql.so
  2          /usr/lib64/libbaccats-sqlite3.so

Enter to keep the current selection[+], or type selection number:
</pre>
Select <code>1</code> to specify the MySQL backend.[http://repos.fedorapeople.org/repos/slaanesh/bacula/README.txt]

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 - NOTE: Package no longer offered in Fedora 18
  • 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.

Concepts and definitions

Basic description of bacula

The basic system comprises three components: the director, the file daemon and the storage daemon. To take them in reverse order, the storage daemon takes data from the file daemon and stores it wherever directed. The file daemon gets the data (files) to be backed up and passes it to the storage daemon. The director then does the rest of the work; that is, defines the task to be performed and the schedule for them to be performed. The basic unit for a backup is the job. This describes what is to be backed-up, when it is to occur and where the data is to be stored.

Some definitions

Volume - basic unit of storage, e.g. a tape, a dvd, a file on a hard drive.

Pool - a collection of volumes, usually used for the same purpose.

FileSet - the files to be backed up.

Job - the overall definition of the work to be performed.

Catalogue - storage area for information about all jobs that have run.

Full Backup - every file in the FileSet is to be copied.

Incremental - a backup that contains all files that have changed since the last full, differential or incremental backup.

Differential - a backup that contains all files that have changed since the last full backup.

Configuration files

To configure each component there is a .conf file in /etc/bacula. Each file defines the interconnectivity with the others, so you need make sure all the passwords agree one with another (you'll see what I mean when you look at the details). bacula-sd.conf defines the storage devices that you want to use, and bacula-fd.conf merely defines itself. The main work is done in bacula-dir.conf, which sets up the everything else. The configuration files are used to define those components that are to be run automatically: ad-hoc jobs can be run through the console.

Workflow

The method of operation for bacula is that the requisite data is stored on Volumes, which are essentially container files stored on differing media. These volumes are organized into Pools in a many to one relationship. Filesets are the collections of files that you want to backup using the same volumes. The timing for preforming backups are defined using Schedules, and all these are tied together as jobs, which define the pool (and hence volumes) to be used to create backups of the files defined within a fileset at a particular schedule.

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'
  • Start the mysql server
su -c 'service mysqld 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('Somes7r0nGp4s5wrD') WHERE User='bacula';
FLUSH PRIVILEGES;

Passwords

Passwords were the confusing part until now. This diagram will help you understand.

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.
I've had had problems while using symbols on bacula's passwords. I'd recommend not using them for now.

Firewall

  • Open up the relevant iptables port for the director
su -c 'iptables -A INPUT -m conntrack --ctstate NEW -m tcp \
-p tcp --dport 9101 -j ACCEPT'
  • Open up the relevant iptables port for the storage
su -c 'iptables -A INPUT -m conntrack --ctstate NEW -m tcp \
-p tcp --dport 9103 -j ACCEPT'

Services

  • Activate the services on boot
su -c 'chkconfig bacula-sd on'
su -c 'chkconfig bacula-dir on'
su -c 'chkconfig bacula-fd on'
  • Start the storage and dir services
su -c 'service bacula-sd start'
su -c 'service bacula-dir start'
su -c 'service bacula-fd start'

Configuring the clients

  • Install the bacula client
su -c 'yum install bacula-client'

Passwords

  • 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.

#
Director {

  Password = "fd_password" # change to a nice and strong password
}

#
# Restricted Director, used by tray-monitor to get the
#   status of the file daemon
#

  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
}

Firewall

  • Open up the relevant firewall port; in this case, 9102
su -c 'iptables -A INPUT -m conntrack --ctstate NEW -m tcp \
-p tcp --dport 9102 -j ACCEPT'

Troubleshooting

How to test

Common problems and fixes

Using MySQL backend in Fedora 17+

Starting in Fedora 17, Bacula RPMs from the official repository are shipped with postgresql support by default. To use the MySQL backend, as shown in the article, do the following:

  • Stop Bacula services if they are running:
su -c 'service bacula-dir stop'
su -c 'service bacula-fd stop'
su -c 'service baucla-sd stop'
  • Change the "libbaccats" (the catalogue library) symlink to the real library. To change to a different backend, issue the following command:
su -c 'alternatives --config libbaccats.so'

There are 3 programs which provide 'libbaccats.so'. You'll see something like the following:

  Selection    Command
-----------------------------------------------
   1           /usr/lib64/libbaccats-mysql.so
   2           /usr/lib64/libbaccats-sqlite3.so
*+ 3           /usr/lib64/libbaccats-postgresql.so

Enter to keep the current selection[+], or type selection number: 

Select 1 to specify the MySQL backend.[1]

  • Go to the configuration scripts location
 cd /usr/libexec/bacula


  • Change the default_db_type from postgres to mysql in files:
    • create_bacula_database
    • drop_bacula_database
    • drop_bacula_tables
    • grant_bacula_privileges
    • make_bacula_tables
    • update_bacula_tables
    • make_catalog_backup
sed -i -e 's/default_db_type=postgresql/default_db_type=mysql/g' *
  • Start bacula services again:
su -c 'service bacula-dir start'
su -c 'service bacula-fd start'
su -c 'service baucla-sd start'

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 and, if You know what You're doing, then make the necesary changes with cool comments and, maybe, some discussion.

Feel free to propose changes and stuff.
