Hi All,
Can anyone tell me the difference between netbackup volume and image database; as well as when each are updated and kindly share an article or technote for the same.

The image data base contains files that conatin information about 'what' is backed up (a list of files effectively) and where they are backed up (on which media), and by which media server. It also holds information about when the images will expire.
This lives in ...
/usr/openv/netbackup/db/images
This information is updated for example when :
A backup or duplication is run
Images are expired

the volume database contains the following information about a media (tape)

Different parts of NBU catalogs and databases are described and explained in NBU Admin Guide I http://www.symantec.com/docs/DOC3650
Chapter 18 has the following sections:
■ About NetBackup catalogs
■ Parts of the NetBackup catalog

Please note that from NetBackup 7.5 image metadata will now be held in the EMM database, which will provide performance improvements on scheduling, expiration and restoration.

Only part of the image catalog will be in EMM, the 'Image header files' - the corresponding .f file will be in the same location.

Indeed, adding the files file to the EMM database would not provide any improvement as these are data files.
