主要包括rootvg备份和用户数据备份.

1.

操作系统和系统程序的备份:

将一盘新磁带或无用磁带插入磁带机

#tctl

-f

/dev/rmt0

rewind

#smit

mksysb

在"备份设备或文件"中添入"/dev/rmt0"后回车.

系统会运行很长时间,

等到屏幕显示OK后拿出磁带.

这时候,

系统备份完成.

注意:

mksysb仅备份rootvg中已安装的文件系统.

2.

恢复

·

启动机器进入维护模式

参见安装手册,

当出现"Welcome

选3

"Start

·

恢复系统

继续选4

"Install

Backup"

出现"Choose
