Recovery

[KINGSLEY_1]

Dear Sirs,

I am back again with more questions about recovery. I hope i have not gotten on your nerves so far. Just bear with me since i love hp-ux and want to get the best solution for my institution in case of a crash.

Last week your contributions on IGNITE went down well with me and i tell you i am now comfortatble with it.

In spite of this, i am still thinking about something that i want you to help me.

Supposing my harddisk crashes and i had a backup of VG00 which i used DATA PROTECTOR to backup, after installing hp-ux on a fresh harddisk can't i restore the backup made from DATA PROTECTOR earlier to have all my patches, configurations, interfaces for my banking software etc intact and ready to use?

Thank you.

The first problem I see with that approach is that installing a fresh copy of HP-UX does not mean that you have Data Protector installed. You will have to install that separately, configure it, restore it's database, etc, etc. Quite a complex task.

If you just let Ignite do the recovery, data protector will be recovered automatically and you can then restore as needed.

There is no reason for not using ignite as it is a free software. You know if you have ignite backups, you can recover your system if it crashes.

Hi Pete!

In my environment we have a separate server that houses DATA PROTECTOR. It is enterprise solution.

What i meant was that in case i took backup of VG00 of the banking software server with DATA PROTECTOR(which is sitting on a seperate server) and the banking server crashes later, can't i just install a fresh copy of hp-ux on the banking server and then restore the backup which i took of the banking server earlier to make my banking server ready for use?

Thanks.

That would make it easier but you will still have to install the Data Protector client onto your newly loaded machine. Not too difficult.

I don't remember from your previous question how your banking software/data/server is laid out so I can only answer in very general terms. If you can describe how things are laid out we might be able to be of more help but I can say that restoring an Ignite tape is going to be faster than loading HP-UX from scratch and all your configurations will be restored as well.

Kingsley sir:

The Fundamental point is the Ignite is designed as a Recovery solution --- and in Business/Mission Critical environments - time is a big factor...

As Pete and RO put across so neatly, the best way for the OS -- VG00 "recovery" is ignite; from DP you can "restore"...

Now kindly assign points to all; otherwise may be I would be the last forum-er to help you out ;-)

Take the ignite backup over network of vg00 and that would be faster way to recover the system instead of doing a fresh install and then restore entire vg00.

HI KINGSLEY,

As i understood from your question is, you wanna know after fresh installation does dataprotector restore all patches
s, configuration & banking software to fresh installed server.

The answer will be no.

If your system is recovered with ignite then the answer will be yes.
DATAPROTECTOR will restore bytes by bytes data to your disk.
Ignite recovery will recover the system image and all patches, configuration & any third party software.

Hope this understand you.

Unless DP is very smart, it can't change the kernel, libc on a system that is currently using them.
