Importing Backup Exec into NBU is discussed in the UNIX Admin Guid vol 1 starting on pg 366 - that is a good place to start. My apologies if you've already gone through the admin guide. I personally have never attempted to import Backup Exec images into NBU, but I know it can be done - not sure about the entire Backup Exec catalog though.
Below is a link to a related technote that references both the 6.0 and 6.5 admin guides.
Hi T_N, sorry I haven't been back earlier.
You can learn more about BETR (it IS included in 6.5 - you should already have it, right now, if you've installed NetBackup!) by looking at the manual pages referenced in the TechNote I linked above. For you, that means pages 330-340 of the Windows Admin Guide I. Get THAT from here:
Veritas NetBackup (tm) 6.5 Administrator's Guide for Windows, Volume 1: Provides information on performing most common configuration and administration tasks with NetBackup 6.5 including: - Managing media, storage units, unit groups, catalogs and lifecycle policies - Firewall Configuration - Firewall ports used for communication
It's a pretty detailed set of instructions for import. (This is actually the same thing rjumfelt said above, only he used the UNIX documentation instead of the Windows version.)
