About Process flow and troubleshooting
The XBSA interface is provided to insulate the XBSA applications from knowing about the internals of NetBackup and the processes and calls that are required to do backups and restores. This is appropriate when the application is working correctly. In the event that a problem occurs, this chapter gives a brief description of the NetBackup processes that get instantiated for each backup and restore. If process fails, a log is produced that contains information pertaining to the failure. All logs should be examined, however, for the root cause of the failure.
