First, yes /tmp is just a regular filesystem on HP-UX. I don't think it need to be backs up. In fact, it really needs a cron job to clear it out.

Some physical volumes are boot physical volumes and they a BDRA (boot data reserved area) which is outside of any logical volume. The BDRA is similiar to a boot block, but more grandiose.

You need some way to recover from the loss of your boot disk. One way is to just re-install the OS, that will recreate the BDRA. Some people have a second boot disk.

I disagree with Hugo about Ignite. I wouldn't use it for true backups. But the make_recovery command will build a bootable tape. And when you boot the bootable tape, it can restore your boot disk. It is a great way to recover from the loss of your boot disk. I have also used it to clone a system.

What program you use for backups is really a matter of opinion. I dislike cpio. HP's fbackup is actually really great. HP says it is intended for system with 1 GB or less. But what they really mean is that if you have a GB or more, they want to sell you a copy of their OmniBack product.

installboot

installboot(1M) 														   installboot(1M)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk	       The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
		       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

	      example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
		   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

	   directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

	   second level program to boot from a disk or CD

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
