利用bacula完成數據的備份恢復

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服務即可

五、bacula備份文件
1. 創建卷組
[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           #創建一個卷組
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
Automatically selected Storage: dbsd
Enter new Volume name: webbak        #卷組名稱，可隨意指定，指定完畢后，會在bacula-dir.conf中Device邏輯字段指定的/home/webbak下生成一個文件
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是可以自動進行label的。想要刪除測試數據的話，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. 執行備份
2.1 第一次增量備份，默認會是一個完全備份 #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
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webjob會做一個完全備份，第二次備份時才執行增量備份

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
*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 23:40:15
Priority: 10
OK to run? (yes/mod/no): mod         #mod修改備份任務參數
Parameters to modify:
     1: Level
     2: Storage
     3: Job
     4: FileSet
