Back Up Your System!

In addition to your normal, periodic system backup procedures, you
should create a backup tape or a network backup of your root volume
group. Do this first before performing a cold-install or update, and again
after the cold-install or update. If a problem occurs, it's a very simple
procedure to restore the system to its original state.
This section offers three alternatives for performing system backups:
fbackup, make_recovery and make_net_recovery.
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, mount 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.
A better alternative to using fbackup/frecover is to use the recovery
commands available with an Ignite-UX server. Ignite-UX recovery
commands offer more flexibility than fbackup/frecover, including the
ability to recover non-bootable systems.
The Ignite-UX server software for HP-UX 11i is provided on the HP-UX
11i OE CD1, and can be either cold-installed along with 11i to create a
new server or specified in the update-ux command to update an existing
Ignite-UX server to 11i. See Chapter 2 for details.
The Ignite-UX server's make_tape_recovery command creates a bootable
recovery tape for an LVM or whole disk file system while it is up and
running. When a system has a logical volume layout, the recovery tape
will only include data from the root volume group, plus data from any
non-root volume group containing the /usr directory.
To create the bootable recovery tape, enter:
/opt/ignite/bin/make_tape_recovery -ACv
where: v is for verbose mode and A specifies the entire root disk or
