Cat_import Requirement

Hi,

just in curiosity, if both the production and DR server(Master/Media) has the same hostname&config do we still need to do catalog import and export.

 

Nope. 
You will see in my post above that I have suggested catalog backup and restore.

Replication of catalogs can also be done.
Supported replication technologies and HOWTO is listed in NBU HA Guide:  http://www.symantec.com/docs/DOC5183

Hi,

Please find the similarirty and difference betwen the environ.

Similarirty:

Hostname,Netbackup Version,Same set of Tapes( Backup in Primary and restoration in secondary),

Diffenernce

IP Address,Tape Libaray Hardware,Extra tapes for Secondary Environment backup.

Hi Marianne,

Any option other than Cluster setup.

Hi Marianne,

The above white paper explains my current 7.1 environment.

In our secondary setup, we have replicated production image database where the soft link is created between the Secondary setup and Replicated Production Image Database.

In 7.1, we just replicate and get the catalog. But in 7.5, I need to perfrom the cat_export and cat_import.

Whether the cat-export and import option is feasilble for daily exercise.?

Suppose, today i have done cat_import in secondary setup and doing restoration. Tomorrow if i go for replication it will change the image database to prev state. Daily do i need to cat_import and Cat_export for entire Image Databse.Entire Production Image Database is around 1 TB.

 

The above white paper got updated last year with a section for 7.5 (and later...) that explains why and how to use cat_export. Have you had a look at it yet?

It seems we are going in circles... same question, same answer.

... feasilble for daily exercise?

You will have to test this and see how long it takes.
cat_export have different options, but nothing to specify a date range. So, there is no option to only export images written since yesterday. 
See Commands manual: http://www.symantec.com/docs/DOC5182
 

In the meantime, it will be best to investigate other HA/recovery solutions.

Have a look at the section of NetBackup in Highly Available Environments Administrator's Guide http://www.symantec.com/docs/DOC5183 that deals with catalog replication (continuous replication that guarantees write order fidelity). It also explains how the relational databases can be moved to the same volume as the image databases so that all databases will be replicated together.
 

Image catalog of 1 TB is very big - looks like it may be time to split environment?

Hi Maranne,

Thanks for yopur reply. We have plan to test the white paper in the coming week.

We plan to import the catalog of specific client for which restoration has to be perfromed in Seconary site.

Will update the status once the testing is over.

Hi All,

We have tested the Partial Catalog recovery in 7.5 and it was sucessful. We plan to do in Prodcution on coming week.. Will update once i done with the Production.

Logged a call with symantec as I faced some error. They recommended to make few changes as per the Technote and completed sucessfully.Will share the details.

Hi Marianne/nagella,

One query, In partial catalog recovery, do the master server name has to be same( both PR and DR).

We have same hostname in exsisting 7.1 setup.( I feel that need not to be same)

But requesting your input in this.
