一、实例演示bacula的完全恢复功能
1、通过差异备份进行完全恢复
操作步骤如下：
*status Status available for: 1: Director 2: Storage 3: Client 4: All Select daemon type for status (1-4): 1 f10-64-build-dir Version: 3.0.2 (18 July 2009) x86_64-unknown-linux-gnu RedHat Daemon started 21-Aug-09 15:01, 1 Job run since started. Heap: heap=253,952 smbytes=84,808 max_bytes=85,641 bufs=266 max_bufs=279 Scheduled Jobs: Level Type Pri Scheduled Name Volume ======================================================================= Incremental Backup 10 21-Aug-09 23:05 Client1 cicro4 Incremental Backup 10 21-Aug-09 23:05 Client cicro4 Incremental Backup 10 21-Aug-09 23:05 BackupCatalog cicro4 Running Jobs: Console connected at 21-Aug-09 16:32 Console connected at 21-Aug-09 16:33 No Jobs running.

从这里的备份状态可知，JobId 为69的任务是一个完全备份， 而JobId 为70、71、72的3个任务是差异备份。下面进行恢复操作：
* restore Automatically selected Catalog: MyCatalog Using Catalog "MyCatalog" First you select one or more JobIds that contain files to be restored. You will be presented several methods of specifying the JobIds. Then you will be allowed to select which files from those JobIds are to be restored. To select the JobIds, you have the following 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 JobId 13: Cancel Select item: (1-13): 3 Enter JobId(s), comma separated, to restore: 69,72 You have selected the following JobIds: 69,72
#这里仅仅指定了差异备份的第一个全备份和差异备份的最后一个备份的JobId，
#即可完全恢复的数据
Building directory tree for JobId(s) 69,72 ... 26 files inserted into the tree. You are now entering file selection mode where you add (mark) and remove (unmark) files to be restored. No files are initially added, unless you used the "all" keyword on the command line. Enter "done" to leave this mode. cwd is: / $ mark cicro 29 files marked. $ done Bootstrap records written to /opt/bacula/var/bacula/working/f10-64-build-dir.restore.1.bsr The job will require the following Volume(s) Storage(s) SD Device(s) ======================================================================= cicro4 dbsd dbdev Volumes marked with "*" are online. 29 files selected to be restored.

(yes/mod/no): yes Job queued. JobId=74 这样，一个完全的恢复就通过差异备份方式完成了。可以在远程备份机器（即FD端）上看到，数据已经恢复了。
