腾讯云 技术升级10大核心产品年终让利>>>   

一、基本拓扑

server端:192.168.232.31 包括:bacula-dirbacula-sd bconsole

client端:192.168.232.32 包括:bacula-fdbconsole

二、安装

1、下载bacula-5.2.13.tar.gz(server和client端),MySQL-community-release-el7-5.noarch.rpm(仅server端)

2、检查系统是否安装mysql相关,若有则删除干净

3、rpm -ivh mysql-community-release-el7-5.noarch.rpm(仅server端)

4、yum installmysql-devel(否则编译安装bacula,./configure提示找不到mysql.h文件)(仅server端)

5、server和client端解压bacula压缩包,cd bacula-5.2.13

server端执行./configure--prefix=/usr/local/bacula --with-mysql

client端执行./configure--prefix=/usr/local/bacula --enable-client-only

6、server端进入/usr/local/bacula/etc目录直接执行以下脚本文件:

./grant_mysql_privileges

./create_mysql_database

./make_mysql_tables

7、执行完成后查看mysql数据库showdatabases能够查看到bacula库

三、配置

提示:除了增加配置文件,还要注意baculadir baculasd baculafd console之间的密码和name相对应。

四、启动

4.1、server端启动:

./bacula start 启动失败提示信息找不到libbacfind-5.2.13.so文件,find查看系统内有该文件

执行:

cd /usr/local/bacula/lib

ln -s/root/bacula-5.2.13/src/findlib/.libs/libbacfind-5.2.13.so./libbacfind-5.2.13.so

./bacula start启动成功

4.2、client端启动:

./bacula start

 

五、使用测试

*exit

!!!!(delete可以删除一个label,cancel可以取消一个job,出现备份任务执行失败的问题,提示新建一个卷,卷不是append的状态,与pool的定义有关)

5.3 测试从备份恢复丢失的文件

5.3.1、首先在客户端删除bacula-dir中的FileSet逻辑段中定义的备份文件(我的测试文件是/aaa/bbb/test1)

5.3.2、恢复操作如下(Client端执行)

[root@ctl02 etc]# ./bconsole

Connecting to Director 192.168.232.31:9101

1000 OK: ctl01-dir Version: 5.2.13 (19February 2013)

Enter a period to cancel a command.

*restore

Automatically selected Catalog: MyCatalog

Using Catalog "MyCatalog"

 

First you select one or more JobIds thatcontain files

to be restored. You will be presentedseveral methods

of specifying the JobIds. Then you will beallowed to

select which files from those JobIds are tobe restored.

 

To select the JobIds, you have thefollowing choices:

    1: List last 20 Jobs run

    2: List Jobs where a given File is saved

    3: Enter list of comma separated JobIds to select

    4: Enter SQL list command

    5: Select the most recent backup for a client

    6: Select backup for a client before a specified time

    7: Enter a list of files to restore

    8: Enter a list of files to restore before a specified time

    9: Find the JobIds of the most recent backup for a client

   10: Find the JobIds for a backup for a client before a specified time

   11: Enter a list of directories to restore for found JobIds

   12: Select full restore to a specified Job date

   13: Cancel

Select item:  (1-13): 5

Defined Clients:

    1: client_fd

    2: ctl01-fd

Select the Client (1-2): 1

The defined FileSet resources are:

    1: Client_epsi

    2: Full Set

Select FileSet resource (1-2): 2

+-------+-------+----------+----------+---------------------+-------------+

附:bacula基础知识

1.支持多种备份方式

(1)完全备份

完全备份就是完整的备份业务数据。

优点:当数据丢失时,只是需要当时的备份就能还原

缺点:由于每天对整个系统进行完整备份,难免造成备份数据大量重复。不但占用大量空间成本也要增加,备份时间长。

(2)增量备份

增量备份以上次备份为基准的备份方式,只是对每次更新或者修改的时间进行备份。

优点:只是备份每天更新或者增加的数据数据量小节点了空间节省成本。

缺点:恢复过程比较麻烦。

(3)差异备份

差异备份是以完全备份为基准的一种备份方式。

假如星期一至星期五,星期1进行了一次完整备份,星期二会把星期1到星期2期间的数据不同的数据进行备份以此类推星期3会把星期1到星期3的不同的数据进行备份。

优点:避免了上面两种备份的缺陷。同时又具有上面两种方式的所有有点,他无需每天对系统做完全备份,因此备份数据量小,备份时间短,节省空间,灾难恢复简单只需要两个备份就可以将系统回复。
