1.1 谁需要bacula

第一章 什么是bacula？

Bacula是一套计算机程序，她允许系统管理员通过不同类型的计算机网络备份，恢复数据,并可检查数据备份的准确性。 Bacula也可以运行于一台计算机，可以备份到不同类型的媒体，包括磁带和磁盘。

在技术方面，它是一个网络客户机/服务器的备份程序。 Bacula相对易于使用和高效，同时提供许多先进的存储管理功能，可以很容易地找到并且恢复丢失或损坏的文件。由于它采用模块化设计，Bacula既适合小型单一的计算机系统，也可用于数百台电脑组成的大型网络。

1.1 谁需要bacula

If you are currently using a program such as tar, dump, or bru to backup your computer data, and you would like a network solution, more flexibility,or catalog services, Bacula will most likely provide the additional features you want. However, if you are new to Unix systems or do not have offsetting experience with a sophisticated backup package, the Bacula project does not recommend using Bacula as it is much more difficult to setup and use than tar or dump.

 

如果您目前使用tar、dump、bru(unix的命令)程序，备份您的计算机数据，你又想要一个网络解决方案，具有更大的灵活性，或目录服务， Bacula将最有可能提供你需要的功能，甚至超出您的需要。然而，如果您是Unix方面的新手或没有准备先进的备份方案的经验， Bacula项目不建议您使用Bacula，因为它相对于tar、dump更难以安装。

 

If you want Bacula to behave like the above mentioned simple programs and write over any tape that you put in the drive, then you will find working with Bacula difficult. Bacula is designed to protect your data following the rules you specify, and this means reusing a tape only as the last resort. It is possible to “force” Bacula to write over any tape in the drive, but it is easier and more efficient to use a simpler program for that kind of operation.

如果你想Bacula的操作像上述简单的程序那样，可以将数据写入放入驱动器的任何磁带，是不可能的，你会发现与那些程序相比较而言，Bacula运用起来要困难的多。 Bacula是用来按照您所指定的规则保护您的数据，这意味着重用一盘磁带只能作为最后的手段。Bacula可能会强行写入任一磁带驱动器，但它的操作比其他简单的程序更加容易和高效。

 

If you are running Amanda and would like a backup program that can write to multiple volumes (i.e. is not limited by your tape drive capacity),Bacula can most likely fill your needs. In addition, quite a number of Bacula users report that Bacula is simpler to setup and use than other equivalent programs.

如果您正在使用的是Amanda，又希望备份程序，可以写入多个Volume（即不仅限于你的磁带驱动器的能力） ，那么Bacula可以满足您的需求。此外，相当数量的Bacula用户认为 Bacula比其他备份程序更易于安装，且使用方便。

 

 

If you are currently using a sophisticated commercial package such as Legato Networker. ARCserveIT, Arkeia, or PerfectBackup+, you may be interested in Bacula, which provides many of the same features and is free software available under the GNU Version 2 software license.

如果您目前使用是先进的商业程序，如Legato Networker. ARCserveIT ， Arkeia ，或PerfectBackup + ，您可能会感兴趣的Bacula ，它不仅提供了许多相同的功能，而且还是免费软件，具有GNU2软件许可。
