GRT enabled backups complete with status code 1 (partially successful) and Nbfsd shows mkdir failed (2)

Problem

When using the Active Directory or Exchange Granular Restore option, backups complete with status code 1 (Partial Success). The message "Exchange granular restore from this image may not work" occurs in the Activity Monitor Job Details. NBFSD log on the Media Server will show the following 'mkdir failed (2) - D:\NBU\temp/nbfsd_ivfs_tempfiles/ivfs__7060_0004'

Error Message

Activitiy Monitor Job Detailed Status will show:
"Exchange granular restore from this image may not work" and "the requested operation was partially successful(1)" Status 1

*Bpgetconfig on Media Server:
C:\Program Files\Veritas\netbackup\bin\admincmd\bpgetconfig" -g Media_Server_Name -L shows:
NBFSD_STAGING_DIR = D:\NBU\temp

*Registry on the Media Server also shows:
HKEY_LOCAL_MACHINE/Software/VERITAS/NetBackup/CurrentVersion/Config
NBFSD_STAGING_DIR = REG_SZ = "D:\NBU\temp"

Cause

The Nbfsd process required for Granular (GRT) to function uses a Temporary Staging area to store temporary files. The default location will go to %install_path%\Netbackup\Temp. If this directory does not exist or the location has moved using the NBFSD_STAGING_DIR registry workaround, or if NetBackup does not have access to this location then the Nbfsd process will fail causing the NetBackup Job to complete with a status 1. This only affects the Granular part of the job and the non Granular data will still be recoverable.

Solution

Use Windows explorer or command line mkdir to make sure the NBFSD staging path exists on the Media Server and is writable by NetBackup.

Check the path either using the bpgetconfig command or for NBU_STAGING_DIR  in the following registry key HKEY_LOCAL_MACHINE/Software/VERITAS/NetBackup/CurrentVersion/Config on the Media Server
 

Applies To

This affects all GRT enabled backups where the NBFSD staging area no longer exists
