概述:
OS: AIX 6100-05-01-1016
NETBACKUP CLIENT: 6.5
本文描述,在AIX 6.1上安装netbackup client,用于备份aix 操作系统中的部分数据目录.
本文涉及的AIX 6.1操作系统上安装了TCP_WRAPPER软件,用于系统的安全加固,所以配置netbackup client时需要开部分权限给netbackup server .

一. 拷贝netbackup client 6.5安装目录到aix系统中
本例中是将安装文件拷贝到/imp32/netbackup_client/目录中.

xxdb_node1:/imp32/netbackup_client/#ls
IA64 NB_65_ICS_1.4.37.3_WIN32 X86 x64
Launch.bat NB_65_ICS_1.4.37.3_WINIA64 autorun.inf
NBClients NB_65_ICS_1.4.37.3_WINX64 install
xxdb_node1:/imp32/netbackup_client#chmod -R 755 *

二. 运行install程序,进行client软件的安装
xxdb_node1:/imp32/netbackup_client#./install

Installing NetBackup Client Software

NOTE: To install NetBackup Server software, insert the appropriate
NetBackup Server cdrom.

Do you wish to continue? [y,n] (y) y
Do you want to install the NetBackup client software for this client? [y,n] (y) y

This package will install RS6000/AIX5 client.

This package will install NetBackup client 6.5.

Enter the name of the NetBackup server : netbackup

Would you like to use "xxdb_node1" as the configured
name of the NetBackup client? [y,n] (y) y

The following temporary file can be deleted after you verify the proper
modification of /etc/inittab:

/tmp/SYMCnbclt-inittab.7602452.i

An automatic startup script, /etc/rc.client.netbackup has been installed.
This will cause NetBackup client daemons to be automatically
restarted each time the server boots.

That file can be deleted after you are sure the install was successful.

三. 配置tcp_wrapper ,允许netbackup server通过bpcp等程序的访问aix主机
本节主要针对aix系统中安装了tcp_wrapper防护软件的情况,如果aix系统没有安装tcp_wrapper,可以跳过此节

xxdb_node1:/imp32/netbackup_client#vi /etc/hosts.allow
##添加相关服务器的访问权限
bpcd:51.123.12.149:allow
vnetd:51.123.12.149:allow
bpcd:51.123.12.143:allow
vnetd:51.123.12.143:allow

其中: 51.123.12.149 是netbackup server
51.123.12.143 是netbackup media server

编辑好/etc/hosts.allow 文件后,通过下面的命令,刷新一下inetd服务
xxdb_node1:/#refresh -s inetd
0513-095 The request for subsystem refresh was completed successfully.

四. 配置aix系统/etc/hosts文件,增加netbackup相关服务器的地址
yxdb_node1:/#more /etc/hosts
......
51.123.12.149 netbackup-svr
51.123.12.143 netbackup-mssvr

五. 配置netbackup相关服务器上的hosts文件,添加aix系统的地址
本例中netbackup有两个服务器,一个主控服务器,一个是媒体管理服务器.
需要编辑windows系统的hosts文件,本例为:C:WINDOWSSYSTEM32DRIVERSETCHOSTS文件
添加如下内容:
51.123.13.150 xxdb_node1

注意:这里的主机名称应该和操作系统的hostname完全相同,否则在备份和恢复的时候容易出现意想不到的错误.
可以事先在aix系统中,运行hostname命令,查看主机名称
xxdb_node1:/#hostname
xxdb_node1

六.配置netbackup client的配置文件bp.conf,添加相关服务器的信息
xxdb_node1:/#more /usr/openv/netbackup/bp.conf
SERVER = netbackup-svr
CLIENT_NAME = xxdb_node1
MEDIA_SERVER = netbackup-mssvr

七.在aix系统中,重新启动netbackup client进程.
在aix系统中安装了netbackup client后,安装程序在/etc/inittab 文件的最后一行增加一下内容，用于在下次操作系统重新启动时自动启动netbackup client 进程。
xxdb_node1:/#more /etc/inittab
......
tty0:2:off:/usr/sbin/getty /dev/tty0
nbclient:2:wait:/etc/rc.client.netbackup start

安装程序在安装的最后，提示有启动netbackup client的操作步骤，但实际上没有成功，在netbackup server 无法识别到。
需要手工启动netbackup client，启动前先关闭一下,然后在启动,如下:
xxdb_node1:/#/etc/rc.client.netbackup stop
xxdb_node1:/#/etc/rc.client.netbackup start

八.定义备份策略后,进行备份
登陆到netbackup server,进入netbackup 管理端,定义备份策略,使用手工启动备份的方式测试一下是否可以正常备份.

笔者曾经因为没有配置好/usr/openv/netbackup/bp.conf文件(忘了配置netbackup media server),导致备份的时候报下面的错误:
bpcd on xxxx_node1 exited with status 59: access to client was not allow

旧的bp.conf文件内容:
xxdb_node1:/#more /usr/openv/netbackup/bp.conf
SERVER = netbackup
CLIENT_NAME = xxdb_node1

添加了media server的配置信息,新的bp.conf文件内容如下:
xxdb_node1:/#more /usr/openv/netbackup/bp.conf
SERVER = netbackup
CLIENT_NAME = xxdb_node1
MEDIA_SERVER = netbackup-ms

然后进行手工启动备份,备份任务开始正常运行.
