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 depends on the policy attribute
.Track log location on the backup host:
Windows:
Install_path\NetBackup\track\master_server\storage_server\client\policy_name\backup selection\S1\
Linux:
Install_path/netBackup/track/master_server/storage_server/client/policy_name/backup_selection/S1/
Track log location on the primary server:
Windows:
Install_path\NetBackup\db\track\master_server\storage_server\client\policy_name\backup selection\S1\
Linux:
Install_path/NetBackup/db/track/master_server/storage_server/client/policy_name/backup_selection/S1/
Where S1, S2… Sn
are the number of streams.
You can manually delete track logs safely if any of the following situations occur:
You can disable the
option.The backup selections are changed.
The policy is renamed.
The storage server that is used to perform the backup is changed.
The primary server that is used to control the backups is changed.
