Difference between Golden Image & Ignite backup

[piyush mathiya]

Hi Gurus,

I want to understand the difference between Golden image & Ignite backup. Which one is good, the advantage & disadvantage and so on...

I think, difference only is sufficient for me, I already got few documents but it is not that much clear.


Thanks in advance,
Piyush Mathiya

Hi Piyush,

Ignite-UX is an HP-UX administration toolset that allows:
* Simultaneous installation of HP-UX on multiple clients
* The creation and use of custom installations
* The creation of recovery media
* The remote recovery of clients

=====================================

Golden image is a toolset of ignite.
A golden image is a combination of a golden archive (an archive with files set to the
newconfig state) and a configuration file describing a systemâ s disk layout and file
system. A golden image is used as a common configuration to install systems.
Golden images allow:
* Increased installation speed versus using swinstall, the command used by
Ignite-UX when installing software from SD depots.
* Exact replication of a customized system configuration to clients.
* Mass deployment of a customized system configuration to clients.
* Disaster recovery at the newconfig level.

======================================

* If you want complete system recovery/cloning you would use golden image.
* Normal ignite backup is used to backup only vg00 and some essential files (The list of essential files to be included in the recovery image is available as a
simple text file: /opt/ignite/recovery/mnr_essentials.)

Hope this helps..

Hello Piyush,

As per my understanding,

Golden Image :

1]In simple words Golden Image is a Zero Defect image/Standard image that can be the ideal image for the clients.

2]Usually it is used while there are number clients to be installed with the same standard of configuration.

3]The advantages of Golden images are

-It is the fresh image with zero defects.

-Installtion speed is high.

-Exact replication of custmized system configurations to clients.

4]The golden image will play very important role at the time of disaster Recovery.


Ignite Image :

1] Ignite Image is OS image of a perticular client.

2]It is not the fresh image as it take the backup of vg00 of existing client so it may have defects/error which old client is having.

3]It may take more time to recover OS from Ignite image.

Hi Piyush,

In very simple terms
Golden image is golden :D
its actually a environment specific image, where u want each server to have same kindda configuration.
Lets say u need a server with some specific patches and configuration, install one server with this config and create golden image from this server and push this image on other clients so you would be having all the clients with same configuration.

It saves ur time to configure each server.

Ignite image is a server specific image as you normally do changes the server setting according to need.So this image would be only specific to this server and could not be used to install other servers.

Hope this would help.

Golden image and Ignite backup/recovery images are similar. The same underlying Ignite tools create both kinds.

Golden images are intended to be general-case images that can be used for multiple, different system targets for system cloning. System identity info are stripped from golden images (for example, hostname is stripped).

Ignite recovery images are specific to a particular system target. Intended to restore or re-install the system from which it was created. These images contain target-specific info, such as hostname.
