Bacula是款开源免费的基于网络的备份工具，可以在网络上各种不同的系统之间，实现文件的备份、恢复和验证等功能。它是基于传统的客户/服务器模式的网络备份程序，被誉为开源平台下

最优秀的网络备份工具之一。其功能强大完全可以和商用备份软件相媲美。Bacula支持完全备份,差异备份,增量备份；支持把备份写到硬盘文件中,也支持写到磁带中，支持多平台异构系统之

间的备份。
一、主服务器 (红色字体是维护人员需要交换的命令)
#cd  /home/bacula
##进入bacula安装目录
#./bacula
Connecting to Director 10.10.2.226:9101
1000 OK: linux-0fdr-dir Version: 2.4.3 (10 October 2008)
Enter a period to cancel a command.
*run
Automatically selected Catalog: dbcatalog
Using Catalog "dbcatalog"
A job name must be specified.
The defined Job resources are:
1: dbjob
2: restrory
Select Job resource (1-2): 1
Run Backup job
JobName: dbjob
Level: Full
Client: dbfd
FileSet: dbfs
Pool: dbpool (From Job resource)
Storage: dbsd (From Job resource)
When: 2012-06-25 15:23:14
Priority: 10 OK to run? (yes/mod/no): yes
Job queued. JobId=990
*list jobs
990| dbjob | 2012-06-25 15:23:18 | B | F | 0 | 0 | R | //这里会出现一个列表,我当前只复制
最新的一个JOBID,这里注意红色的R表示已
经在运行了,要是E或者C就是有问题了，要
是T就表示复制完成了.
*status
Status available for:
1: Director
2: Storage
3: Client
4: All Select daemon type for status (1-4): 3
Automatically selected Client: dbfd
Connecting to Client dbfd at 10.10.2.162:9102
……………………………………………………… //这里省略一部分输出信息
54 Full 1,628 9. 7M OK 25- 8 2012-06-25 15:27 dbjob
//看到这里已经显示OK了,表示备份成功
现在去看看备份路径下面是否生成了备份文件
# du -sh *
9.7M fzh
可以看到这个卷有9.7M的大小了,原来是4K的文件,再次证明了备份成功了.
下面做还原的操作,我们把client端的被备份目录下面文件进行删除
[root@localhost bacula]# rm -rf *
[root@localhost bacula]# ls
二、directory端还原操作
# ./bconsole
