NBU磁带库备份系统的安装步骤

1、软件安装软件安装主要包括masterserver、mediaserver、软件的安装。在备份系 统屮，选择hp做为masterserver,同时充当mediaserver的角色。为便于管理， 确定masterserver作备份系统的global database host,用于存放所有的配置 和备份信息。下面逐一介绍每一种软件的安装过程，软件安装列表见附件三。2. 4. 1 netbackup datacenter masterserver installition安装前作如下准备工作，在mediaserver安装时也要作同样的准备：连接硬件所有mediaserver/masterserver

2、以及带库、磁带机均连接到一台san 光纤交换机。硬件识别在安装软件之前，要保证系统能够识别磁带机和机械手（只需 masterserver识别机械手）#ioscan 一fnc tape系统空间安装masterserver之前，确保系统空间大小：ram 彡512mb安装目录可用空间彡64mb/tmp可用空间 32mb系统配置在备份环境中甸台主机都要修改/etc/hosts文件，提供hostname/ip的 解析。在masterserver端的/etc/hosts文件中增加如下内容：主机iphp10.46.0.xxxsunv880 a10.46.0.132sunv880一b10.46.0.133表2

41、备的配置。机械手用来抓 取、识别磁带，有一条光纤与交换机相连。sanmediaserver执行备份任务时需 要使用机械手，如果机械手设置为共享方式，则sanmediaserver之间要进行 vmd/tldcd等进程间的通讯，这样既增加了配置的复杂程度，同时防火墙要放宽更 多的过滤规则，安全性降低，因此机械手由masterserver(同时也是一个 mediaserver)控制，这样其他mediaserver右对机械手的请求吋，只和masterserver 进行通讯即，这样不仅使配置简化，还堉加y系统安全性，减少丫ip的网络流量, 同时它能满足系统的备份要求。由sanmediaserver共享使

42、用，并且机械手和磁 带机支持device serialization.，这是设备firmware的一个特征，nbu通过设备 序列号识别和标识机械手与磁带机。3. 3介质配j3. 3. 1配置说明介质配置主要包括volume、volume pool及calalog volume配置。一个volume对应一盒磁带，一个volume pool包含多个volume。volume pool概念的 引入是为了便于备份数据的管理。可以根据不同的备份类型划分不同的pool,例 如文件系统备份和数据库备份可以放在不同的pool里；也可以根据不同的部门或 不同的主机划分不同的pool。每盒磁带上都有一个条形码(b

43、arcode)，在磁带库 加电自检时都可识别到。在veritas nbu中，每一个volume都有一个meida 1d， 此id可以自己定义，也可以由nbu自动定义，它根据barcode产生mediald。一般 情况下由nbu自动产生mediald，这样mediald与barcode可以对应。另外，系统提供一个scratch volume pool，它的作用是当其他volume pool 屮没有可用的磁带时，nbu从scratch volume pool屮抓取一盒未曾用过的volume 加入其中，以保证备份能顺利进行。volume pool己用slot规划slotsybase-pool1-15

51、eunit的failover，我们引入/存储单元组(storageunit group )，它把ha系统中两台mediascrvcr的storageunit组成一个group，同时它 也可以和storageunit样用于polciy的定义中。nbu执行备份时，如果group中 的第一个storageunit可用，则用第一个进行备份，否则就用第二个。如果备份 的cl ient冋吋也是连接到storageuni t的mediaserver,则本地的storageunit拥 有优先权去响应备份请求。4. 2 storageunitstorageunit的配罝可以通过图形界面进行，步骤如下：stepl
