Modification:
When an online catalog backup is run, it normally generates four jobs on NetBackup 6.5: a parent job, a child job for copying database files to a staging directory, a child job for NetBackup relational database tables, and a child job for catalog images and configuration data.

Here is an example of how a catalog backup might look in the Activity Monitor (Figure 1):

 

In this example:

  • JOBID 1 is the parent job.
  • JOBID 2 is a child job that makes a temporary copy of database files to a staging directory (/usr/openv/db/staging for UNIX and Linux, <install_path>\NetBackupDB\staging for Windows)
  • JOBID 3 is a child job for NetBackup relational database(s)

Configuration files (server.conf, database.conf, vxdbms.conf)
Database files:
NBDB.db
NBDB.log
EMM_DATA.db
EMM_INDEX.db

If BMR has been installed:
BMRDB.db
BMRDB.log
BMR_DATA.db
BMR_INDEX.db

  • JOBID 4 is a child job for image catalog backup.

Note: Transaction logs are truncated after a successful full or incremental backup.
If the transaction logs are manually changed or deleted, there could be a hole in the recovery.
