Centos6.3 deployment of Bacula for Remote Backup Recovery

Bacula is an open-source cross-platform network backup tool that provides an enterprise-class CS-based backup solution. You can back up, restore, and verify data integrity.

Features: Full backup, Incremental backup, and differential backup are supported. Multiple recovery methods are supported, including ext3, ext2, reiserfs, xfs, jfs, smbfs, iso9660, and ntfs) supports a variety of backup media support a variety of operating systems powerful internal functions a complete bacula backup system, consists of the following five parts Director Daemon: monitors all backup, recovery, verification, archiving transactions, and custom backup and recovery file plans, and records the operating status of the entire system in one database file. Its configuration file is bacula-dir.conf. Storage Daemon (SD): it is mainly responsible for backing up data to the Storage medium, and transmitting data from the Storage medium during data recovery. Its configuration file is bacula-sd.conf. File Daemon (FD): a Daemon installed on the machine on which data is backed up. When backing up data, the Daemon is responsible for transferring files out, receives and recovers data when restoring data. The configuration file is bacula-fd.conf. Console: The management Console. You can use this console to connect to Director Daemon for backup and recovery management. Monitor: Process Monitoring end. Workflow: 1. Connect to ctor through the console and start the Backup recovery operation. 2. Director transfers record information from your own database to coordinate the storage SD and client FD tasks. 3. The client FD is responsible for verifying the operation permission of ctor. If the verification is successful, it is allowed to connect to the storage-side SD4. The client FD connects to the SD according to the request sent by Director, back up data on the FD end to the storage medium specified by the SD end, or transmit data on the SD end storage medium back to the specified position of the FD on the client end to complete the backup and recovery process.

I personally feel that Bacula seems to be rarely used in domestic production environments, and I do not know how many people have used this backup tool. However, I personally think this backup tool is still very good, if you like Bacula or study Bacula, contact me to learn more about this backup tool!

1. Install the Bacula master

1.1. Introduction

This document describes how to install Bacula from the source program using simple commands.

If you are using another Linux release version of Fedroa, Redhat, or Centos, refer to this document. The command name and path may vary depending on the release package or operating system. Therefore, you may need to work out the installation documents.

If you are using another Linux or other system, or want to learn more, you can find it on the official Wikipedia (http://wiki.bacula.org.

3. Configure the SD of bacula

SD can be a separate server, or on a machine with Director, this example will put the SD and Director end together for configuration, the SD configuration file is a bacula-sd.conf

Maximum Concurrent Jobs = 20

}

Director {# define a storctor that controls StorageDaemon

Name = chenyi-dir # The "Name" value must be the same as the Name of the Director logical segment in the bacula-dironf configuration file of ctor.

Password = "u1nxynwrinyi?sulvmkp/uGTYiy2C5OY7wnSqkz2voU" # The "Password" value here must be the same as the Storage logical segment Password in the Director end profile bacula-dir.conf

}

Director {# define a monitor Director

Name = chenyi-mon # The "Name" value must be the same as the Name of the Console logical segment in the bacula-diconf configuration file of ctor.

Password = "/I9QK/9tvB63eOHT2TGJuO7KMzOkrNGi8UtOMGq9LHga" # here the "Password" value is the same as the Password in the Console logical segment in the Director end configuration file bacula-dir.conf

Monitor = yes

}

Device {# define Device

Name = FileStorage # defines the Name of the Device, which is referenced in the Storage logical segment Device item in the Director configuration file bacula-dir.conf

Media Type = File # specifies the storage Media Type. File indicates that the File system is used for storage.

Archive Device =/tmp/backup # Archive Device is used to specify the backup storage media, such as cd, dvd, and tap. Here, the backup files are saved in the/tmp/backup directory.

LabelMedia = yes; # use the Label command to create a volume File

Random Access = Yes; # Set whether to use Random Access to the storage media. Here, select yes.

AutomaticMount = yes; # indicates whether to use the storage device automatically when it is turned on.

RemovableMedia = no; # whether to support removable devices, such as tap or cd. Select no here.

AlwaysOpen = no; # Whether to ensure that the tap device is always available. The tap device is not used here, so it is set to no

}

Messages {# define a log or message processing mechanism for the storage device SD

Name = Standard

Director = chenyi-dir = all

}

At this point, the main control end of Bacula is roughly configured, and then the process of Bacula will be started [this article is from www.itchenyi.com, but you must keep the original link]

Configure the Client (for the Client to be backed up)

1. Compile and install Bacula

Set the environment variable and set $ HOME to/usr/local.

[Root @ chenyi bacula-5.2.6] # HOME =/usr/local/

[Root @ chenyi bacula-5.2.6] # CFLAGS = "-g-Wall"

Run the Bacula configuration script. The configure option has been introduced in the <install Bacula Console> section. The following is an example:

[Root @ chenyi ~] # Tar zxf bacula-5.2.6.tar.gz

[Root @ chenyi ~] # Cd bacula-5.2.6

Pre-Configuration
