一、bacula概述

1.bacula的組件
  bacula,被譽(yù)為開源軟件中最好的備份還原軟件,它提供了企業(yè)級的客戶機(jī)/服務(wù)器的備份解決方案，能夠通過網(wǎng)絡(luò)來管理文件的備份，恢復(fù)和核實(shí)工作.既有windows版本的,也有Linux，Unix的.
一個完整的bacula備份系統(tǒng)，由以下五個主要部分或服務(wù)組成：
Directory:  管理所有備份,恢復(fù),驗(yàn)證,和存檔事務(wù),定制備份和恢復(fù)文件的計(jì)劃.
Storge:     指定進(jìn)行存儲和恢復(fù)文件屬性和數(shù)據(jù)的物理備份媒介.
File:       安裝在被備份機(jī)器上的程序,將被directory調(diào)用時候,它提供關(guān)于自己的操作系統(tǒng)、文件屬性、數(shù)據(jù)等資料.
Console:    管理控制臺，與directory進(jìn)行通訊.
Catalog: 負(fù)責(zé)維護(hù)所有備份文件的索引和數(shù)據(jù)庫.Catalog服務(wù)允許系統(tǒng)管理員或用戶能夠快速地找到并恢復(fù)任何需要的檔案。catalog服務(wù)是Bacula和簡單的tar，bru備份命令的主要區(qū)別，因?yàn)閏atalog維護(hù)所有Volume使用情況的記錄，所有任務(wù)的運(yùn)行情況，和所有檔案的保存情況，允許有效的恢復(fù)和Volume管理。 Bacula目前支持的三個數(shù)據(jù)庫（postgresql、mysql、sqlite），在安裝Bacula時,必須選擇其中之一。
Monitor:   監(jiān)控directory、file、storage的守護(hù)進(jìn)程

2. 部署結(jié)構(gòu)
主機(jī)名          ip地址          應(yīng)用角色               OS  
baculaserver    192.168.32.30   Director、SD、Console  rhel5.5
baculaclient    192.168.32.31   FD                     rhel5.5
 
二、安裝
1.bacula服務(wù)器端安裝和初始化
1.1. bacula軟件安裝
[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 
#指定安裝路徑和所用數(shù)據(jù)庫
[root@baculaserver bacula-5.0.1]# make && make install
 
1.2 MySQL數(shù)據(jù)庫初始化
[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
#在執(zhí)行上面三行mysql初始化時，默認(rèn)由數(shù)據(jù)庫管理員root執(zhí)行，因此可能需要輸入root密碼或設(shè)置root密碼為空。
 
2.bacula客戶端安裝
[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 
#指定安裝路徑，和只安裝客戶端組件
[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     #主控臺名稱，自定義，要求與bacula-dir.conf中定義相同
  DIRport = 9101            #控制臺服務(wù)器端口
  address = 192.168.32.30   #控制臺服務(wù)器IP，不要用localhost
  Password = "xgjYPXCfgFT6ZS/9tQQTtfrFZ90CFFfIcj+qDKm8FpO0"  #控制臺密碼
}
 
2. bacula的Director端配置（bacula-dir.conf)
2.1 bacula-dir.conf的組成
bacula-dir.conf是Director端的配置文件，也是bacula的核心配置文件，該文件由以下10個邏輯端組成：
Director：定義全局設(shè)置
Catalog：定義后臺數(shù)據(jù)庫
Jobdefs：定義默認(rèn)執(zhí)行任務(wù)
Job：自定義一個備份或恢復(fù)任務(wù)
Fileset：定義備份哪些數(shù)據(jù)，不備份哪些數(shù)據(jù)
Schedule：定義備份時間策略
Pool：定義供Job使用的池屬性
Client：定義要備份的客戶端
Storage：定義數(shù)據(jù)的存儲方式
Messages：定義發(fā)送日志報(bào)告和日志的記錄
 
2.2 bacula-dir.conf配置
[root@baculaserver etc]# vim bacula-dir.conf
Director {                            #控制臺的全局配置

3. bacula的SD配置(bacula-sd.conf)

4. bacula的FD端配置(bacula-fd.conf)
[root@balucaclient etc]# vim bacula-fd.conf
Director {
  Name = 2012-02-15-dir         #定義一個允許連接FD的控制端，必須與bacula-dir.conf中Director邏輯端名稱相同

  Maximum Concurrent Jobs = 20
}
 
# Send all messages except skipped files back to Director
Messages {
  Name = Standard
  director = balucaclient-dir = all, !skipped, !restored
}
 
四、 bacula服務(wù)的啟動 
1. 在服務(wù)器端啟動bacula的Director Daemon和Storage Daemon
1.1 啟動方式一
[root@baculaserver etc]#/usr/local/bacula/etc/bacula {start|stop|restart|status}
 
1.2 啟動方式二：分別管理各個配置端的方式，依次啟動或關(guān)閉每個服務(wù)
[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，在此無需自動bacula-fd服務(wù)
[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 
#在啟動bacula的所有服務(wù)前，必須啟動MySQL數(shù)據(jù)庫，否則連接bacula的控制端是會報(bào)錯。
 
2. 在客戶端啟動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，在此只需啟動bacula-fd服務(wù)即可
 
五、bacula備份文件
1. 創(chuàng)建卷組
[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           #創(chuàng)建一個卷組
Automatically selected Catalog: MyCatalog

Automatically selected Pool: dbpool

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.
#只有在使用磁帶卷時才需要這樣，而像我們剛才使用的磁盤卷，Bacula是可以自動進(jìn)行l(wèi)abel的。想要刪除測試數(shù)據(jù)的話，就將/tmp目錄下的卷直接刪除，再使用drop_mysql_tables和make_mysql_tables腳本  
                                                                                                  
2. 執(zhí)行備份
2.1 第一次增量備份，默認(rèn)會是一個完全備份  #備份前fd中文件有index1.html
*run
A job name must be specified.
The defined Job resources are:
     1: webjob
     2: Restoreweb
Select Job resource (1-2): 1        #選擇備份任務(wù)
Run Backup job
JobName:  webjob
Level:    Incremental
Client:   2012-02-15-fd
FileSet:  dbfs
Pool:     dbpool (From Job resource)
Storage:  dbsd (From Job resource)
When:     2012-02-15 23:29:58
Priority: 10
OK to run? (yes/mod/no): yes
Job queued. JobId=1          
#到處為止，可以開始備份了，在bacula-dir.conf文件中定義的webjob是一個增量備份，因此這個備份只是一個增量操作，由于是第一個備份，因此默認(rèn)webjob會做一個完全備份，第二次備份時才執(zhí)行增量備份
 
2.2 第二次增量備份，只做增量操作 #備份前fd中文件有index1.html、index2.html                                                                                                         
*run
A job name must be specified.
The defined Job resources are:
     1: webjob
     2: Restoreweb
Select Job resource (1-2): 1
Run Backup job
JobName:  webjob
Level:    Incremental
Client:   2012-02-15-fd
FileSet:  dbfs
Pool:     dbpool (From Job resource)
Storage:  dbsd (From Job resource)
When:     2012-02-15 23:37:00
Priority: 10
OK to run? (yes/mod/no): yes
Job queued. JobId=2                                                                                                                              
#這是第二備份，只做一個增量操作
 
2.3 第三次備份，手動改為差異備份  #備份前fd中文件有index1.html、index2.html 、index3.html

也可以
  status dir      查看director 的狀態(tài)
  status client   查看 client  的狀態(tài)
  status storage  查看 storage 的狀態(tài) 
 
2. show  查看資源信息。
  pools   filesets  clients storages schedule jobs message
 
3. list llist 
list pools | jobs | jobtotals | media <pool=pool-name> | files <jobid=nn>
 
4. run  手動運(yùn)行一次編好的任務(wù)。
 
5. reload    從新載入配置文件（當(dāng)修改配置文件后用這個，不需要停止服務(wù)）
 
6. estimate  對某次任務(wù)進(jìn)行評估。它會連接到客戶端，并輸出這次任務(wù)的fileset 中 文件數(shù),和這次備份任務(wù)所占的空間。
 
7. purge prune
  一般不會用到，我們設(shè)定的是過期自動清除。
  purge    危險�。。。�！ 這是一個危險命令。他能清除一個客戶端的所有備份任務(wù)，文件，和卷。
  prune    這個命令和 purge 相似，但安全很多，它只會清除過期的文件，任務(wù)，和卷。 
8. time    查看時間。 
9. delete   刪除volume ， pool 或某次任務(wù)。
10. disable 和 enable 是一對，它可以禁止和啟用某個任務(wù)。
11 cancel   取消一次正在運(yùn)行的任務(wù)。例如：某次任務(wù)由于設(shè)置不當(dāng)，卡住不動了,我們就可以使用這條命令，去取消這次任務(wù)。
   cancel 20   取消任務(wù)ID=20 的任務(wù)。 
12 update   修改 volumes ,pool 參數(shù)。
