1.7 Bacula不是什么

Bacula is a backup, restore and verification program and is not a complete disaster recovery system in itself, but it can be a key part of one if you plan carefully and follow the instructions included in the Disaster Recovery Chapter of this manual. With proper planning, as mentioned in the Disaster Recovery chapter, Bacula can be a central component of your disaster recovery system. For example, if you have created an emergency boot disk, a Bacula Rescue disk to save the current partitioning information of your hard disk, and maintain a complete Bacula backup, it is possible to completely recover your system from “bare metal” that is starting from an empty disk. If you have used the WriteBootstrap record in your job or some other means to save a valid bootstrap file, you will be able to use it to extract the necessary files (without using the catalog or manually searching for the files to restore).

 

Bacula 是一个备份，还原，验证的程序，而本身不是一个完全的灾难恢复系统，但它可以成为一个关键组成部分之一，如果你仔细计划，并按照指示包括在本手册里灾难恢复章节。通过适当的规划，如所提到的灾难恢复章节， Bacula可以成为你的灾难恢复系统一个核心组成部分。例如，如果您已经创建了一个紧急启动磁盘，一个Bacula救援磁盘去挽救当前的分区信息的硬盘，并保持一个完整的Bacula备份，有可能从”裸机”完全恢复你的系统，也就是开始从一个空盘。如果在你的工作你使用了WriteBootstrap记录或其他一些手段来挽救一个有效的启动文件，你将能够使用它来提取必要的文件。（不使用目录或手动搜索的文件恢复）

 

1.8 Bacula Services间的合作

The following block diagram shows the typical interactions between the Bacula Services for a backup job. Each block represents in general a separate process (normally a daemon). In general, the Director oversees the

 

flow of information. It also maintains the Catalog.
