hpux操作系统磁带备份与恢复
一.扫描磁带机(注意:定期用清洗带为磁带机做清洗)

二.进行磁带备份
根据磁带类型,放入同类型磁带
/opt/ignite/bin (这个是make_tape_recovery 所在的目录)
make_tape_recovery -A v (默认磁带 /dev/rmt/0mn,此备份为常用备份方式)
注意:如果扫描出的磁盘是 /dev/rmt/0mn ,并且类型是HP,可以直接使用上述命令。
如果扫描出的磁盘是 /dev/rmt/2mn(或者其他),并且类型是HP,就需要指定路径: make_tape_recovery -A v -a /dev/rmt/2mn
-A : 指定要备份整个Root disk / Volume Group
-v : 用于显示备份过程的提示信息
-a:指定路径
备份成功显示信息如下:

三.磁带恢复系统
把磁带放入磁带机,把安装光盘放入光驱,
磁带恢复系统,需要用到安装光盘引导,到此步骤,选择 Boot from CD/DVD,Recover from Tape,然后进行恢复
