利用bacula完成数据的备份恢复

 
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)

#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:
     1: webjob
     2: Restoreweb
Select Job resource (1-2): 1        #选择备份任务
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:
     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                                                                                                                              
#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
Select Job resource (1-2): 1
Run Backup job
JobName:  webjob
Level:    Incremental
Client:   2012-02-15-fd

OK to run? (yes/mod/no): mod         #mod修改备份任务参数
Parameters to modify:
     1: Level
     2: Storage
     3: Job
