简介: 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.
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:与directory进行通讯.
Catalog:负责维护所有备份文件的索引和数据库.
Monitor:监控directory、file、storage的守护进程.
使用2台服务器来做这个网络备份的测试环境,环境如下:
10.10.2.226 作为directory、storage、catalog.
10.10.2.162 作为file.
bacula的安装不是很复杂,我这里安装的是bacula的2.4.3版本的.
#tar zxvf bacula-2.4.3.tar.gz
#./configure --with-mysql
#make&&make intall
默认情况下,bacula的安装路径为/etc/bacula.
#./grant_mysql_privileges
#./ create_mysql_database
#./ make_mysql_tables
在这里说明下,bacula的主要配置都在directory这个配置文件里面的,这个算是一个核心文件了,一定要搞清楚里面配置文件的配置项都代表什么意思,否则很难配置成功.

directory端的配置：

SD配置:
Storage {
Name =dbsd //这里要与director配置文件的storage的name一样
SDAddress=10.10.2.226 //这里是SD的IP
SDPort = 9103
WorkingDirectory = "/var/bacula/working"
Pid Directory = "/var/run"
Maximum Concurrent Jobs = 20 //job的最大连接数
}
Director {
Name =linux-0fdr-dir //这里要与directory的name相同
Password = "5jipKA7pekDel6BUjgIwD3LkPPBgxcecbLpLfl9puj0c " //这里与directory中storage的password相同
}

AutomaticMount = yes;
RemovableMedia = no;

}
Messages {

director = linux-0fdr-dir = all
}
console端的配置：
Director {
Name = linux-0fdr-dir //这里要与directory的name相 同
DIRport = 9101
address = 10.10.2.226 //console端的IP
Password = "MJ8SyFywMm+4ntJf2EupggRWIWE6LozmLfIKC8J9nYt7"
//这个密码要与directory的password一样
}
在server端,只启动directory和storage的进程,启动命令如下:
#./bacula-ctl-dir start
#./bacula-ctl-sd start
启动之后,要给bacula添加存储介质,
linux-0fdr:/etc/bacula # ./bconsole
