Linux系统上安装和配置Backup Exec 12.5 Oracle Agent详细步骤

一、安装部分

Backup Exec是一款主要用于Windows平台的数据保护产品，但是它也包含了用于Linux或Unix的代理程序。要清楚你所使用的Backup Exec支持哪些Linux或Unix系统，请访问技术支持网站上的软件兼容性列表，以现在用户数量最多的BE10d为例，它的兼容性列表网址是：

http://support.veritas.com/docs/278254

你可以在软件兼容性列表中发现两个用于Linux或Unix的代理产品，它们的兼容性不同：

Remote Agent for Linux and UNIX Servers (RALUS) Compatibility // 即RALUS，新的代理程序，收费，性能较高。

Legacy Linux/UNIX/Mac Compatibility  // 传统的代理程序，免费，性能较低，以后会被RALUS取代。

查过兼容性列表之后，如果你所使用的操作系统包括在兼容性列表之中，就可以考虑采用Backup Exec来保护你的系统。如果兼容性列表中没有列出你所使用的系统，则可能存在兼容性问题，建议先进行测试，确认可以使用再购买。

下面将介绍RALUS的安装（Legacy Agent现在很少有人使用，就不介绍了）

下面假定你的Media Server（安装有Backup Exec的备份服务器）己经安装好，并且安装了RALUS选件。

首先，RALUS的安装程序较大，被放在单独的光盘中提供。如果没有安装光盘，也可以通过Symantec网站下载：

http://support.veritas.com/docs/279329

下载的安装包是压缩的，需要先解包，光盘中的安装程序不是压缩的，可以直接安装。下面是我的安装记录（用的是BE11d RALUS安装程序），中间加了一些解释（红色部分）。

[root@redhatas3 /]# mount /mnt/cdrom

[root@redhatas3 /]# cd /mnt/cdrom

[root@redhatas3 cdrom]# ./installralus     // 执行安装脚本

Remote Agent Media Server Configuration

To display the Remote Agent as a selection in a media server's backup selection tree, and to be able to specify a local network for use between the Remote Agent and a media server, enter the names or IP addresses of the media servers that you want the Remote Agent to communicate with.

An IP Address: XXX.XXX.XXX.XXX

A Host Name: COMPUTERNAME

Enter a directory host:mybeserver   // 输入备份服务器的名称，RALUS会定期向备份服务器通告自己的存在，收到通知后备份服务器会在备份选择窗口中显示该Linux/Unix主机。

Do you want to add another name or address for this agent? [y, n] (n)

Remote Agent Media Server Configuration

Hostnames and/or IP addresses verification:

Is this information correct? [y, n] (y)

Remote Agent User Group Setup

To perform backups, you must have a 'beoper' user group. This user group can be created only if you are not using NIS server. Your system will be scanned to detect a NIS server, group and membership.

Press [Return] to continue:

Checking if system uses NIS server: .................................. No

The installer will now check your system for the 'beoper' user group and root membership.

Press [Return] to continue:

Checking for 'beoper' user group: .............................. Not Found

Checking for 'root' user membership in 'beoper' user group: .... Not Found

You can create 'beoper' user group manually or you can choose to have it created automatically.
