Veritas Netbackup简介
Veritas NetBackup 简称 NBU 是一款商业化的备份和恢复软件，在金融行业占据了 86%以上的市场份额，除了软件产品以外也开始推自家的备份一体机。关于产品方面的介绍交给 NBU 的售前就行了，行业内负责备份恢复的朋友基本也都清楚我就不再赘述了。文章重点记录了 NBU 培训时的原理和三层架构，比较核心的内容当然是 Policy 部分，上述内容都在 PPT 里有详细的介绍，此外还增加了简单的动手实践环节方便大家在自己的虚拟机中练习和理解。
Vistor简介
Vistor虚拟带库系统是cofio公司的一款虚拟带库软件解决方案，用来实现高性能的磁盘备份，同真实带库一样的磁带管理机制提高了管理效率。Vistor支持iscsi和FC，可以模拟多种型号的磁带库，允许创建多个不同的带库，支持TSM、NBU、LegatoNetworker、Bakbone等多款备份软件。
Vistor配置虚拟带库
系统版本：Centos 5.2 x32位
软件版本：vistor 2.1.1
安装Vistor
1.将vistor_2_1_1.tgz上传到vistor服务器中
2.解压vistor
[root@vistor vistor]# tar xf vistor_2_1_1.tgz
3.运行./vs-install

4.将系统盘挂载到系统下，手动安装所需系统包
kernel-devel-2.6.18-128.el5.i686.rpm libgomp-4.1.2-42.el5.i386.rpm kernel-headers-2.6.18-92.el5.i386.rpm glibc-headers-2.5-24.i386.rpm glibc-devel-2.5-24.i386.rpm gcc-4.1.2-42.el5.i386.rpm [root@vistor CentOS]# rpm -ivh kernel-devel-2.6.18-92.el5.i686.rpm warning: kernel-devel-2.6.18-92.el5.i686.rpm: Header V3 DSA signature: NOKEY, key ID e8562897 Preparing... ########################################### [100%] 1:kernel-devel ########################################### [100%] [root@vistor CentOS]# rpm -ivh libgomp-4.1.2-42.el5.i386.rpm warning: libgomp-4.1.2-42.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897 Preparing... ########################################### [100%] 1:libgomp ########################################### [100%] [root@vistor CentOS]# rpm -ivh kernel-headers-2.6.18-92.el5.i386.rpm warning: kernel-headers-2.6.18-92.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897 Preparing... ########################################### [100%] 1:kernel-headers ########################################### [100%] [root@vistor CentOS]# rpm -ivh glibc-headers-2.5-24.i386.rpm warning: glibc-headers-2.5-24.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897 Preparing... ########################################### [100%] 1:glibc-headers ########################################### [100%] [root@vistor CentOS]# rpm -ivh glibc-devel-2.5-24.i386.rpm warning: glibc-devel-2.5-24.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897 Preparing... ########################################### [100%] 1:glibc-devel ########################################### [100%] [root@vistor CentOS]# rpm -ivh gcc-4.1.2-42.el5.i386.rpm warning: gcc-4.1.2-42.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID e8562897 Preparing... ########################################### [100%] 1:gcc ########################################### [100%]
5.安装完成后再次运行vm-install

6.vistor安装完成后默认安装在目录/usr/cofio/vistor
查看web是否可用，使用http:192.168.1.101:5050登陆，首次登陆无密码，直接点击login登陆。
[root@vistor vistor]# netstat -anpt | grep 5050 tcp 0 0 :::5050 :::* LISTEN 6689/httpd tcp 0 0 ::ffff:192.168.1.60:5050 ::ffff:192.168.1.108:60573 ESTABLISHED 6705/httpd
点击setting 进入设置页面
输入vistor软件的key，需要将系统时间改为2008年
主页里显示可以管理磁带库
在Linux操作系统可以启动和停止Vistor虚拟磁带库
[root@vistor vistor]# ./vs-httpd start [root@vistor vistor]# ./vistor start Load iscsi transport modules ViStor services started successfully
配置ISCSI TargetAddress：
[root@vistor iscsi]# cd/usr/cofio/vistor/iscsi [root@vistor iscsi]# ./bw_core_cfg -L 192.168.1.60 1 Bridgeworks Protocol-Neutral APPl (v3_01_ALPHA26 Jan 31 2008 13:43:40)
使用lsmod验证磁带库及磁带机驱动加载状态
[root@vistor vistor]# lsmod | grep st st 38749 0 scsi_mod 134605 7 st,sg,initiator_wrapper,vs_mls,vs_drv,libata,sd_mod [root@vistor vistor]# lsmod | grep sg sg 36189 0 scsi_mod 134605 7 st,sg,initiator_wrapper,vs_mls,vs_drv,libata,sd_mod
至此Vistor虚拟磁带库配置就完成了，紧接着配置客户，这里的客户端是安装Netbackup 7.7.3的Nbumaster Server服务器，首先在控制面板中选择iscsi发起协议，点击发现门户，将vistor的targetaddress地址输入进去
点击目标选择刚才添加的iqn，点击连接
iqn连接完成后，在设备管理器中就能查看到磁带驱动器和媒体更换其设备，至此就可以对虚拟带库进行使用了
接下来配置NBU，识别添加磁带存储设备
添加配置存储设备
选择对应的主机添加存储设备
扫描设备发现4个驱动器以及1个机械手
上拉驱动器到配置选项，点击NEXT继续配置完成
配置完成后在Media选项菜单点击右键选择清点磁带设备
首先清点磁带，然后选择更新卷组配置
至此，NBU磁带设备全部添加完成识别，所需用的时候可以新建不同的磁带Pool分配使用
