difference between NBU catalog and EMM?

Please can you read the manuals, all answers are there.

This is covered on the admin guide. To answer the question, emm db is an a sql database that contains many db tables that contain various information such as master/ media server details, the media db, details of image, copy, fragments for disk backups,- there are too many tables to list and only tech support need to be concerned about them.

The image db contains info on what files are backed up, and where they are stored. At nbu 7.5 part of the image db will be moved to the emm db. These two parts, along with some other config files make up the catalog.

From the NetBackup 7.1 Admin  for Unix  guide (part 1) page 742

The catalog consists of the following parts:

■ The image database.

The image database contains information about the data that has been backed

up. It is the largest part of the catalog.

See “About the NetBackup image database” on page 743.

■ NetBackup data that is stored in relational database files.

The data includes media and volume data describing media usage and volume

information, which is used during the backups.

See “About the NetBackup relational database” on page 745.

■ NetBackup configuration files.

The configuration files (databases.conf and server.conf) are flat files that

contain instructions for the SQL Anywhere daemon.

See “About the NetBackup server.conf file” on page 774.

See “About the databases.conf file” on page 775.

NO CHANGES should EVERY be made to the image catalog manually (unless directed by techniocal support) - this is the quickest and easiest way to damage the catalog and loose data,

I've been looking at this post all weekend and one question comes to mind:

Why on earth are you point blank REFUSING to READ anything? Do you really want to be spoon-fed?

I have already TWICE (in another post and in private emails) referred you to the following topic in  NBU Admin Guide 1:

Parts of the NetBackup catalog

This section contains ALL of the info that you need. It lists the directory structures, explains the different components and also how to protect them.

Once you have read this section and anything is still unclear, pkease come back with reference to the specific section that you don't understand, and we will happily try to explain/clarify.
