bacula完全恢複與不完全恢複功能的實戰示範

一、執行個體示範bacula的完全恢複功能

1、通過差異備份進行完全恢複

操作步驟如下：

*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.

從這裡的備份狀態可知，JobId 為69的任務是一個完全備份，而JobId 為70、71、72的3個任務是差異備份。下面進行恢複操作：

* 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
