RESILIENT_BACKUP_JOB_DEFERRAL_CACHE_FILE_PATH option for NetBackup servers
This directory path specifies where the media server processes write the job deferral caches. The deferral cache files are written to /usr/openv/tmp on Linux, and install_path\NetBackup\temp on Windows by default. For the Flex Appliance, the deferral cache file path is set to /mnt/nbstage/usr/openv/tmp.
NetBackup backups generate metadata relative to the amount of data that is backed up. If a media server has many active backups running in parallel, NetBackup can write a significant amount of data to the deferral cache files.
Be aware of the relationship between the RESILIENT_BACKUP_JOB_DEFERRAL_CACHE_FILE_PATH and MINIMUM_DEFERRAL_CACHE_FREE_SPACE_MB values. Use RESILIENT_BACKUP_JOB_DEFERRAL_CACHE_FILE_PATH to specify where to write the cache information. Use MINIMUM_DEFERRAL_CACHE_FREE_SPACE_MB to specify how much free disk space to maintain.
