Can netbackup catalog resotation be done if I have all below files and folders ( from Master Server) on a remote server:

C:\Program Files\Veritas\Volmgr\database
C:\Program Files\Veritas\NetBackup\db
C:\Program Files\Veritas\NetBackup\var
C:\Program Files\Veritas\NetBackup\vault
C:\Program Files\Veritas\Volmgr\vm.conf

Why do you want to do a catalog restore - please explain.

There is more to a catalog restore than just file and folders.

Which version of NBU? Those folders look like pre-6.x version folders, missing the EMM database location.

Why would you have a copy of certain folders an not proper catalog backup?

Short answer is no.

As Nicolai points out, there is more to a catalog backup than just files and folders.  For starters, unless the copy of the NBDB was made with servces stoppped, it will be useless.

Generally speaking, attempts at recovery via any method other than a 'proper' catalog restore end in failure, or leave is system in a 'only partially' working state.

Hi Nicolai, 

I am new to Backups and have observered in our existing infra that Catalogues are failing frequently due to tape frezzes , media full and unavailable, drive down, and various others. Also in past we had faced an issue where in our backup master server went down and was not turning up, and we were not able to fetch, of all the hundreds to media, which one had the latest catalogue backup. Thus we were exploring secondary backup option for catalogues

You have not mentioned your NBU version?

In your 1st post, you listed folders that were only applicable to pre-NBU 6.0 versions.

The issues that you describe sounds like you are battling with old, failing servers, tape drives and media.

You need to find out from your management how serious they are about Data Protection.
You cannot manage an environment with unreliable server(s) and devices.

 

Hi ,
We are having 6.5. What would be  EMM database location ?

6.5 went out of support years ago, you really need to get that upgraded to 7.7.3 or 8.0.

The DB is located in /usr/openv/db/data - but these files cannot be backed up with the services running.  There is also part of the catalog in /usr/openv/netbackup/db/images.  Aside of those areas, the catalog backup backs up many other files that required for a complete restore - so there is no shortcut

A temp idea would be to configure a filder as basic disk, and backup the catalog to that area  It is very very far from idea, as it is on the server itself (as opposed to removeable tape) but is better than nothing.  The smallish part of the catalog is NBDB itself, this could be backedup with this command.

/usr/openv/db/bin/nbdb_backup -online /usr/openv/db/staging

You could then copy the files in /usr/openv/db/staging off to another machine, or back them up to tape (smallish backup so maybe that would work).  This would at least protect the NB database.  The .f files (under ...db/images ) are usually the largest part of the catalog and difficult it would seem for you to protect at the moment, but these can be re-created (it's not quick to do, but not impossible, by reading in the backup tapes).

Ultimately, as Marianne expertly explains, you need to sit down with management and explain that your backup server(s) need some very serious attention, very urgently (and probably money spending as well) to sort out the issues it is having.

Thanks Marianne,

We are putting up a business case with our management for new procurments ( New Tape Library and Veritas latest version ) . 

We are planing to have 2 master servers, each at remote location. These 2 master servers would act as media sever for their own locations onnected to their respective tape library. Apart from these, there would be 7 media servers, each at different physical locations and connected to their respective tape library.

I am, at this point not sure, if its possible. But we want configuration such that, out of these 7 media servers, 3 media servers should have one master servers as its primary master servers ( say , master server A ) and other master server ( say , Master server B ) as secondary i.e in case primary master server is down, secondary master server become active for these 3 media servers. Similary vice versa for remaining 4 media severs. For these 4 media servers , master server B is primary and master server A is secondary

All these media and master servers would be able to reach each other over network after allowing access from 2, 3firewalls that come in way

 

For above, Tape library has been identified but we are yet to zero down to veritas licenses/products required as the catalog is confusing.  Can some one assist with the same.

There is no such thing as primary and secondary master server in NBU. A media server can only 'belong' to one master server.
There are various suggestions and options in NBU High Availability Guide, like Catalog replication with and without clustered master server.  
Else, Dedupe storage that will enable Automatic Image Replication, etc...

We cannot assist here with backup design.
There are simply too many factors to take into account.

You need to contact a knowledgeable reseller who can sit with your backup, network and server team to design a proper Production and DR backup solution.

All the best!
In the meantine, you need to make it very clear to your management that the aging infrastructure cannot cope with the day-to-day backup demands.
