For VG00, you can use make_net_recovery.

For the rest of the data you need to use whatever your corporate backup product is.

Hi,

you use make_sys_image if you want to use an ignite server (and use the image for several installations)
Else you use make_net_recovery or make_tape_recovery.

Normally you only create this backup for vg00.
Anything else you can backup with any backup utility (for ex. fbackup). Be sure that your applications are down for this backup.

what are the files that I should check from the OS perspective and h/w perspective to swing the server to another N class..

I think this is more likely a system clone. Here is a link with basic clone process, following it can lead you to the right direction.

One last query..

I have a NFS mount set up... How can I use make_net_recovery to take images here at the mount.. also how to do it with fbackup..

For make_net_recovery to work.. wat s/w do I need on the Server..

Re: Backup's

Tingli — Thu, 20 Aug 2009 14:34:06 GMT

to make make_net_recovery work, you need ignite installed in your ignite server.

V. Nyga — Thu, 20 Aug 2009 14:45:38 GMT

Hi,

it makes no sense to make images from nfs mounts.

fbackup is in SAM - Backup and Recovery - Interactive Backup and Recovery -- then you need a connected backup device (tape) or use a remote backup device.

Hmmm - with make_sys_image there are some system file which are not stored, they are created new - /etc/passwd, /etc/hosts, /etc/fstab (your nfs informations)
I don't know how it is with make_net_recovery ...

from the above link I see that both mk_sys image and mk_nte recovery can be used to clone systems... each has it's own pro's & con's

I have a rp5450 and I am cloning it to a new rp5450 and move this a different place..

Which method do u think would be the best.. In any method where will the image be stored...

Do I nees to have a Different Ignite server for this or should I install the Ignite depot on each of these boxes...

Re: Backup's

Tingli — Thu, 20 Aug 2009 14:59:32 GMT

I still suggest using the clone method, as you can just use the existing old ignite file to build the new system. You can use a single server for the build up but you need to have the new machine and the server in the same subnet to boot it up.

Re: Backup's

Grayh — Thu, 20 Aug 2009 15:05:29 GMT

ok..

So do I need to hit this command at source(I have to make a exact copy of this on new server) or target(new system)

#make_net_recovery

Is it just that one line.... or do I have to specify a sequence of commands.. if so plz advise

Re: Backup's

Tingli — Thu, 20 Aug 2009 15:21:46 GMT

Usually, I make the ignite backup through gui from there server. It is a lazy but easy way.

Re: Backup's

Grayh — Thu, 20 Aug 2009 15:26:38 GMT

Thats nice... Could you plz tell how to take backup using ignite in GUI...

Could you plz give me any doc on how to do it...

Re: Backup's

Tingli — Thu, 20 Aug 2009 15:30:44 GMT

In your server, set up its DISPLAY first. Then use ignite & to start it. The server will scan the net to find the clients by itself and creates icon for each client. And you can open the icon, which will lead you to where you want.

Gokul Chandola — Thu, 20 Aug 2009 15:36:03 GMT

Hi,
For Ignite backup you have to install ignite s/w in a separate machine that will work as Ignite Server and from client end we can difine ignite Server for that and we will push for backup and time-to-time we can synchronise it and whenever we required restore.
We can Full system restore to Put Server ip in booting time.
Your full system will restore.

please read the Ignite document for that, this is simple and very safe But you need a separate server for that.

Grayh — Thu, 20 Aug 2009 15:37:18 GMT

I am confused...

Should I take backups to clone the target from the source or from the Ignite server...

Where should I hit these commands or invoke the gui...

First, you make a vg00 backup from your old system. Then you create a backup clone following the clone document. After that, you install the new system from the backup clone.
