Output from the NetBackup support utility (nbsu)

By default, the nbsu command creates the output as a compressed file in the same directory where the nbsu executable is located. The format of the command output is:

NBSU_hostname_role_mmddyyyy_timestamp.extension

For example:

  • UNIX/Linux: NBSU_mylinuxvm_master_11072017_152100.tgz

  • Windows: NBSU_mywindowsvm_master_11072017_152100.cab

The NetBackup environment where nbsu runs determines the particular files that nbsu creates. nbsu runs only those diagnostic commands that are appropriate to the operating system and the NetBackup version and configuration. For each diagnostic command that it runs, nbsu writes the command output to a separate file. As a rule, the name of each output file reflects the command that nbsu ran to obtain the output. For example, nbsu created the NBU_bpplclients.txt by running the NetBackup bpplclients command and created the OS_set.txt file by running the operating system's set command.

Each output file begins with a header that identifies the commands that nbsu ran. If output from more than one command was included in the file, the header identifies the output as an "internal procedure."

The following is an example of part of the nbsu output file for the bpgetconfig command. The STDERR is shown as the output of the command and is captured in the output file. Exit status is outputted into the output file as follows: Exit status: <exit status code>

If a supported archive program is available on the host where nbsu runs, nbsu bundles its output files into an archive file. If a supported compression utility is available, nbsu compresses the archive file. Otherwise, the individual output files remain unarchived and uncompressed.

An example of a compressed archive file that nbsu created is as follows:

/usr/openv/netbackup/bin/support/NBSU_host1_master_01172018_220505.tgz

where host1 is the name of the host on which nbsu ran, and primary indicates that the host is a NetBackup primary server. The date is embedded in the file name in the mmddyyyy format.

nbsu supports tar for archive and gzip for compression.

A complete description of nbsu is in the NetBackup Commands Reference Guide.
