HP-UX 11i Version 1.6 Installation and Configuration Guide

Preparing for Cold Install
Backing Up Your System
Chapter 252
Backing Up Your System
In addition to your normal, periodic system backup procedures, you
should create a network backup of your root volume group (see
“Cold-installing HP-UX 11i v1.6” on page 35). Do this first before
performing a cold-install, and again after the cold-install. If a problem
occurs, it’s a very simple procedure to restore the system to its original
state.
This section offers two alternatives for performing system backups:
fbackup, and make_net_recovery.
Using fbackup Many administrators use the basic fbackup command to back up the
entire system to tape. You do not need to unmount any imported file
systems; fbackup does not cross NFS boundaries unless specified.
Using the normal tape location to do a full backup, insert a new tape and
enter:
fbackup -f/dev/rmt/0m -i -v
Later, if you wish to return the system to its previous state, use the
frecover command. See the fbackup (1M) manpage for examples.
Ignite-UX recovery
command
For recovering a system, a better alternative to using fbackup and
frecover is to use the make_net_ recovery command available with
Ignite-UX, which offers more flexibility than fbackup and frecover,
including the ability to recover non-bootable systems.
The Ignite-UX server software for HP-UX 11i v1.6 is provided on the
HP-UX 11i v1.6 DVD, and can be cold-installed along with HP-UX 11i
v1.6 to create a new server. See “Updating Your Ignite-UX Server” on
page 48 for details.
NOTE You cannot use make_tape_recovery and make_recover with HP-UX
11i v1.6. The make_net_recovery command is available.
Using make_net_
recovery
The Ignite-UX server has the make_net_recovery command to create a
system recovery archive on another system on the network. The archive
created by make_net_recovery is specific to the system it was created
