About the track logs for accelerator
NetBackup accelerator uses track log to detect the new, change, and modify files in the subsequent Full and Increment backups. The track log is a binary file that you should not attempt to edit. For D-NAS policy each backup stream maintains its own track log. The number of backup streams depend on the policy attribute .
Track log location on the backup host:
