Preparing to Migrate to HP-UX 11i v2
Backing Up Your System
Chapter 472
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
Chapter 5, “Cold-Installing HP-UX 11i v2,” on page 79). 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 several alternatives for performing system backups:
fbackup and frecover, and make_net_recovery and
make_tape_recovery.
Using fbackup and
frecover
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
commands
For recovering a system, a better alternative to using fbackup and
frecover is to use the make_net_recovery or make_tape_recovery
commands available with Ignite-UX, which offer more flexibility than
fbackup and frecover, including the ability to recover non-bootable
systems.
The Ignite-UX server software for HP-UX 11i v2 is provided on the
HP-UX 11i v2 DVD, and can be cold-installed or updated along with
HP-UX 11i v2 to create or update a new server. See “Updating Your
Ignite-UX Server” on page 65 for details.
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
for and its identity includes hostname, IP_address, networking
information, and so on. In the event of a root disk failure, you use the
Ignite-UX server to restore the system by installing the recovery archive.
