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

        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。

                           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.
Do you want installer to create 'beoper' user group? [y, n] (y)
Do you want to use specific group ID when creating 'beoper' user group? [y, n] (n)

    Creating group 'beoper': ............................................ Done  // 如果系统不采用NIS管理用户，安装向导会在本地组中添加beoper组，属于beoper组中的用户可以用于备份该主机上的资源，在备份服务器连接该主机时使用。

Do you want to add the 'root' user to 'beoper' user group? [y, n] (y)

    Adding 'root' user to 'beoper' user group: ......................... Done  // 如果将root用户加入beoper组，则可以在备份服务器使用root用户连接到该主机，可备份或恢复根下的所有文件和目录。

二、配置部分
BE11d的Oracle Agent与以前的版本有本质的不同，它采用RMAN来备份Oracle数据库，也支持Linux系统上的Oracle数据库，很多用户对它的配置还不熟悉，特别是在Linux系统上的配置，下面是我所做的一个配置实例。中文部分是我加的说明。

[root@ora10g lib]# /opt/VRTSralus/bin/AgentConfig // 安装好RALUS之后，请使用root用户来配置代理程序。

Symantec Backup Exec Remote Agent Utility

1. Configure database access
2. Configure Oracle instance information
3. Quit
Please enter your selection: 1 // 要完成两个部分的配置，数据库访问和Oracle实例，下面先配置数据库访问。

2. Edit system credentials used for Oracle operations
3. Remove system credentials used for Oracle operations
4. View system credentials used for Oracle operations
5. Quit

Enter the password:
Re-enter password:
Validating credentials.......
Do you want to use the full computer name/IP address for Oracle operations? (Y/N):n // 指定名字的好处是，避免因为计算机名字或IP地址的变化导致Recovery Catalog中的记录信息混乱。
Do you want to use a custom port to connect to the media server during Oracle operations? (Y/N): n

// 默认的端口号是5633，建议不要改动它，除非这个端口己经被其它应用程序占用，如果这里做出了改变，介质服务器端也要做同样的修改。

Commit Oracle operation settings to the configuration file? (Y/N): y
SUCCESS: Successfully added the entry to the configuration file.

//上述配置中的计算机名（如果没有指定就是在介质服务器上连接这台机器时所使用的名字或IP地址），用户名和密码必须也介质服务器全局选项中Oracle选项页中配置的为Oracle和DB2所设置的验证信息完全一致。

Configuring machine information
Choose one of the following options:
1. Add system credentials for Oracle operations
2. Edit system credentials used for Oracle operations

Enter the Oracle database SYSDBA password:
Re-enter password:
Validating credentials.......
Enter the media server name or IP address: be11d // 这里输入介质服务器的名字
Do you use a recovery catalog? (Y/N):n // 如果你己经安装好了用做Recovery Catalog的实例并做了初始化，就在这里输入实例名和登录账号，如果没有Recovery Catalog就选n，RMAN编录信息将被写入控制文件。

Do you want to use a customized job template? (Y/N): n // 这里不需要定义作业模板名，因为你在RMAN脚本中可以使用send “NBBSA_JOB_TEMPLATE=模板名”命令为每个备份指定不同的模板名，当然你要预先在介质服务器端创建好这个模板。

Commit Oracle operation settings to the configuration file? (Y/N): y
Renamed file /u01/app/oracle/oracle/product/10.2.0/db_1/lib/libobk.so to /u01/app/oracle/oracle/product/10.2.0/db_1/lib/libobk.so.oracle.org
Created symbolic link for /opt/VRTSralus/bin/libobk.so at /u01/app/oracle/oracle/product/10.2.0/db_1/lib/libobk.so // 配置向导在Oracle数据库的库文件目录下将libobk.so链接到RALUS的文件，BE接管了RMAN向磁带机写入数据的备份接口，RMAN向 sbt或sbt_tape设备写入数据时，RALUS会把数据传送到介质服务器。
