ignite backup

Hi,

I was reading coldinstall process. It discusses ignite backup ... My question is, is it necessary to use ignite to do the backup? Is it necessary to setup an ignite server? Is it ok to use the same thirdparty tool that is currently being used? Please explain the difference briefly.

You do not need to do an Ignite backup to do a cold install.

The confusion you may be running into is that the Cold Install process uses the Ignite Install Interface. Its the same product.

Ignite is the best tool for backup up your boot configuration. It is the only tool that can create a disaster recovery tape that you can boot off of and restore your system configuration in hours.

Please clarify your goal for further advice.

Hi Kiran,

You can take a look at the ignite site, which could probably answer some of your quetions.

Hope this helps.

Thanks you very much for the reply...

We have to perform cold-install on 4-5 boxes ..

Pre-Migration Tasks for Everyone
In addition to your normal, periodic system back-up procedures, you should create a back-up 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 is a very simple procedure to restore the system to its original state.

This section offers three alternatives
...

If you plan to migrate many systems in your enterprise, we recommend using an Ignite-UX server to create an OS archive from which to migrate. This archive can contain the HP-UX 11.0 OS, other applications and any needed patches. Once the archive is in place, either on the Ignite-UX server or on another system, migration on each client system is a single-pass operation; you will only need to reboot once.

We have a third party tool (omniback) that is used to perform daily backups. Can we use that here?

Also, could you clarify what the following means?

Ignite-UX recovery commands offer more flexibility than fbackup/frecover, including the ability to recover non-bootable systems.

I am sure omniback will help during disaster recovery but I am not really clear about NONBOOTABLE SYSTEMS ... Don't know why HP emphasized ignite and how is it different for a backup. Would it make recovery faster in case of a problem?

Thanks in advance.

fbackup can restore files. Its good at that.

Ignite, As I stated earlier or in other thread can restore your system from non-bootable to bootable condition.

Scenario: A patch install goes bad, system won't boot.

Boot system off ignite tape that you made right before the patch install with make_tape_recovery. System is bootable in a couple of hours. You looke good.

Hi,
OmniBack (or, the new product name Data Protector) is not a 3-party product, it is genuine HP.

It is possible to use OB or DP for OS backup ("disk delivery# or rawdisk backup method) but, it is not as easy to restore the system from as an Ingnite backup when it come to distaster recovery. To use OB for distaster recovery you must first boot the system on a secondry disk before you can use OB.

With Ignite you can boot the system on the Ignite server (or Ignite tape).

Both Ignite and OB/DP is HP products but, intended for different use. Ignite is a pure system recovery tool, OB/DP a general backup tool.

Addition:
- omniback is a normal backuptool like legato networker (does this still exist?), great for backup of datas but not for a re-install of a OS

- with ignite/make_net_recovery you are also able to modify the size of partitions and other parameters at the installation.

use ignite for the OS and omniback for data and (perhaps) large applications

Hi,

I have a couple of questions ..

Is there a way to determine if a server is ignite confugured fully ... This box has /opt/ignite/bin ... that has just one .. print_manifest

Can we cold install multiple systems over a network ...

Any network requirements to sync a remote system with ignite server?

Thanks in advance.

There should be a lot more in /opt/ignite/bin than that. Download and install the latest version from here:

Hi,

That means if one machine in a n/w is ignite, it can backup/restore other systems in the n/w. correct? If so, any newtork config/things to check?

Thanks again ....

I'm not all that familiar with doing Ignite over the network, but they do have a make_net_recovery facility which makes a network image to another machine for disaster recovery purposes. You can also create a so-called "Golden Image" which can then be used to "Ignite" new servers. There's quite a bit of information about these and other Ignite topics on the url I gave you.

Thanks, could someone tell a common procedure ... if there are 3 systems in 3 different locations, and if all of them require ignite backup .. should we make ignite tape physically at 3 locations? Thanks in advance.
