一、bacula概述
1.bacula的组件
bacula,被誉为开源软件中最好的备份还原软件,它提供了企业级的客户机/服务器的备份解决方案，能够通过网络来管理文件的备份，恢复和核实工作.既有windows版本的,也有Linux，Unix的.
一个完整的bacula备份系统，由以下五个主要部分或服务组成：
Directory: 管理所有备份,恢复,验证,和存档事务,定制备份和恢复文件的计划.
Storge: 指定进行存储和恢复文件属性和数据的物理备份媒介.
File: 安装在被备份机器上的程序,将被directory调用时候,它提供关于自己的操作系统、文件属性、数据等资料.
Console: 管理控制台，与directory进行通讯.
Catalog: 负责维护所有备份文件的索引和数据库.Catalog服务允许系统管理员或用户能够快速地找到并恢复任何需要的档案。catalog服务是Bacula和简单的tar，bru备份命令的主要区别，因为catalog维护所有Volume使用情况的记录，所有任务的运行情况，和所有档案的保存情况，允许有效的恢复和Volume管理。 Bacula目前支持的三个数据库（postgresql、mysql、sqlite），在安装Bacula时,必须选择其中之一。
Monitor: 监控directory、file、storage的守护进程
bacula各个组成部分的关联性
2. 部署结构
主机名 ip地址 应用角色 OS
baculaserver 192.168.32.30 Director、SD、Console rhel5.5
baculaclient 192.168.32.31 FD rhel5.5
二、安装
1.bacula服务器端安装和初始化
1.1. bacula软件安装
[root@baculaserver ~]# tar -zxf bacula-5.0.1.tar.gz
[root@baculaserver ~]# cd bacula-5.0.1
[root@baculaserver bacula-5.0.1]# ./configure --prefix=/usr/local/bacula --with-mysql
#指定安装路径和所用数据库
[root@baculaserver bacula-5.0.1]# make && make install
1.2 MySQL数据库初始化
[root@baculaserver ~]# cd /usr/local/bacula/etc
[root@baculaserver etc]# ./grant_mysql_privileges
[root@baculaserver etc]# ./create_mysql_database
[root@baculaserver etc]# ./make_mysql_tables
#在执行上面三行mysql初始化时，默认由数据库管理员root执行，因此可能需要输入root密码或设置root密码为空。
2.bacula客户端安装
[root@baculaclient ~]# tar -zxf bacula-5.0.1.tar.gz
[root@baculaclient ~]# cd bacula-5.0.1
[root@baculaclient bacula-5.0.1]# ./configure --prefix=/usr/local/bacula --enable-client-only
#指定安装路径，和只安装客户端组件
[root@baculaclient bacula-5.0.1]# make && make install
三、bacula的配置
1. bacula的console端配置(bconsole.conf)
[root@baculaserver etc]# vim bconsole.conf
# Bacula User Agent (or Console) Configuration File
#
Director {
Name = 2012-02-15-dir #主控台名称，自定义，要求与bacula-dir.conf中定义相同
DIRport = 9101 #控制台服务器端口
address = 192.168.32.30 #控制台服务器IP，不要用localhost
Password = "xgjYPXCfgFT6ZS/9tQQTtfrFZ90CFFfIcj+qDKm8FpO0" #控制台密码
}
2. bacula的Director端配置（bacula-dir.conf)
2.1 bacula-dir.conf的组成
bacula-dir.conf是Director端的配置文件，也是bacula的核心配置文件，该文件由以下10个逻辑端组成：
Director：定义全局设置
Catalog：定义后台数据库
Jobdefs：定义默认执行任务
Job：自定义一个备份或恢复任务
Fileset：定义备份哪些数据，不备份哪些数据
Schedule：定义备份时间策略
Pool：定义供Job使用的池属性
Client：定义要备份的客户端
Storage：定义数据的存储方式
Messages：定义发送日志报告和日志的记录
2.2 bacula-dir.conf配置
[root@baculaserver etc]# vim bacula-dir.conf

}
四、 bacula服务的启动
1. 在服务器端启动bacula的Director Daemon和Storage Daemon
1.1 启动方式一
[root@baculaserver etc]#/usr/local/bacula/etc/bacula {start|stop|restart|status}
1.2 启动方式二：分别管理各个配置端的方式，依次启动或关闭每个服务
[root@baculaserver etc]#/usr/local/bacula/etc/bacula-dir {start|stop|restart|status}
[root@baculaserver etc]#/usr/local/bacula/etc/bacula-sd {start|stop|restart|status}
[root@baculaserver etc]#/usr/local/bacula/etc/bacula-fd {start|stop|restart|status}
#由于fd端在baculaclient上，在此无需自动bacula-fd服务
[root@baculaserver etc]# netstat -tnpl | grep 910
tcp 0 0 0.0.0.0:9101 0.0.0.0:* LISTEN 1507/bacula-dir
tcp 0 0 0.0.0.0:9102 0.0.0.0:* LISTEN 1333/bacula-fd
tcp 0 0 0.0.0.0:9103 0.0.0.0:* LISTEN 1323/bacula-sd
#在启动bacula的所有服务前，必须启动MySQL数据库，否则连接bacula的控制端是会报错。
2. 在客户端启动bacula的File Daemon
[root@baculaserver etc]#/usr/local/bacula/etc/bacula {start|stop|restart|status}
[root@baculaserver etc]#/usr/local/bacula/etc/bacula-fd {start|stop|restart|status}
#由于baculaclient只做fd端，在此只需启动bacula-fd服务即可
五、bacula备份文件
1. 创建卷组
[root@baculaserver etc]# ./bconsole
Connecting to Director 192.168.32.30:9101
1000 OK: 2012-02-15-dir Version: 5.0.1 (24 February 2010)
Enter a period to cancel a command.
*label #创建一个卷组
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
Automatically selected Storage: dbsd
Enter new Volume name: webbak #卷组名称，可随意指定，指定完毕后，会在bacula-dir.conf中Device逻辑字段指定的/home/webbak下生成一个文件
Automatically selected Pool: dbpool
Connecting to Storage daemon dbsd at 192.168.32.30:9103 ...
Sending label command for Volume "webbak" Slot 0 ...
3000 OK label. VolBytes=202 DVD=0 Volume="webbak" Device="dbdev" (/home/webbak)
Catalog record for Volume "webbak", Slot 0 successfully created.
Requesting to mount dbdev ...
3906 File device "dbdev" (/home/webbak) is always mounted.
You have messages.
#只有在使用磁带卷时才需要这样，而像我们刚才使用的磁盘卷，Bacula是可以自动进行label的。想要删除测试数据的话，就将/tmp目录下的卷直接删除，再使用drop_mysql_tables和make_mysql_tables脚本
2. 执行备份
2.1 第一次增量备份，默认会是一个完全备份 #备份前fd中文件有index1.html
*run
A job name must be specified.
The defined Job resources are:

#到处为止，可以开始备份了，在bacula-dir.conf文件中定义的webjob是一个增量备份，因此这个备份只是一个增量操作，由于是第一个备份，因此默认webjob会做一个完全备份，第二次备份时才执行增量备份
2.2 第二次增量备份，只做增量操作 #备份前fd中文件有index1.html、index2.html
*run
A job name must be specified.
The defined Job resources are:

#这是第二备份，只做一个增量操作
2.3 第三次备份，手动改为差异备份 #备份前fd中文件有index1.html、index2.html 、index3.html
*run
A job name must be specified.
The defined Job resources are:
1: webjob
2: Restoreweb

也可以
status dir 查看director 的状态
status client 查看 client 的状态
status storage 查看 storage 的状态
2. show 查看资源信息。
pools filesets clients storages schedule jobs message
3. list llist
list pools | jobs | jobtotals | media <pool=pool-name> | files <jobid=nn>
4. run 手动运行一次编好的任务。
5. reload 从新载入配置文件（当修改配置文件后用这个，不需要停止服务）
6. estimate 对某次任务进行评估。它会连接到客户端，并输出这次任务的fileset 中 文件数,和这次备份任务所占的空间。
7. purge prune
一般不会用到，我们设定的是过期自动清除。
purge 危险！！！！！ 这是一个危险命令。他能清除一个客户端的所有备份任务，文件，和卷。
prune 这个命令和 purge 相似，但安全很多，它只会清除过期的文件，任务，和卷。
8. time 查看时间。
9. delete 删除volume ， pool 或某次任务。
10. disable 和 enable 是一对，它可以禁止和启用某个任务。
11 cancel 取消一次正在运行的任务。例如：某次任务由于设置不当，卡住不动了,我们就可以使用这条命令，去取消这次任务。
cancel 20 取消任务ID=20 的任务。
12 update 修改 volumes ,pool 参数。
