Hi All,
Just a query came in here,
 
After facing Disaster, at the time of DR. We need to have the Server with same OS as it was earlier.
How can we get the details of OS previously there on the server.

By using a configuration plan and a configuration system.

Alternative mail/dropbox netbackup policy configuration to a location in the world far away.

Thanks Nicolai,
 
I was thinking the same, but is this the only way we can get the details ?
 
Can we do it in a way, like import the catalog media on other server and get the /usr/openv/netbackup/version file restored. Would it work anyhow ?

There is not need for OS to be exactly the same.

It only needs to be of the same 'OS family'.

So, if you know you had a Windows master, you can install a 'current' version, like W2008 R2. catalog restore will work.

If you had a Unix or Linux master, any supported Unix/Linux server will work.

See all of these TechNotes for general guidelines:

Thanks Marianne,
 
Thanks for sharing such an important T.N, they really made the concept clear to me now.

Do you want info for all client or just the master/media ?

I mean - in a real DR where all servers are gone everybody will run around and ask what server XXX ran (that what I had in mind).

I also do recommend for Windows system to run "systeminfo" once every day and pipe the information to a file that netbackup the can protect. In a DR this file can be restored and version verified.

I guess systeminfo can be mail outside the organization as well if using Windows master and media servers.

Following the expert advice aboe from the wonderful Marianne and amazing Nicolai, the answer should be in the system documentaion that is protected so it is available in the case of DR.

Ths should document evrything required to rebuild the server the way it was - OS type / version / patch level etc ...

In the case of DR for a master server, a good starting point is the nbsu -c -t output - this contains a lot of informtion that could be useful.  It could be scripted so that it is email / stored away from  the master.

We still don't know what your actual requirement is...
- just OS info on NBU master?
- or info of all servers and clients in the environment?

Some more reading matter:

DOCUMENTATION: Recovering a Master Server at a disaster recovery site from a catalog backup requires the same topology.

PS: Although above TN says 'same OS', we know from TNs mentioned in my previous post that this means 'same OS family'. 

I certainly hope that you are asking this for DR preparation purposes...
If so, well done. Good documentation and DR testing is key when preparing.
