NetBackup tuning parameters for the backup host
Following are the NetBackup tuning parameters for the backup host:
DNAS_LOOKAHEAD_CACHE_SIZE_PER_VOLUME_MB: The crawler uses the DNAS_LOOKAHEAD_CACHE_SIZE_PER_VOLUME_MB memory for cache purposes during each volume's backup job.
The default value is 100 MB per volume. During a backup, the crawler looks ahead to the snapshot file system and uses this additional cache space to store information for the backup job.
You can configure the parameters in the
bp.conf
file for the backup hosts of NetBackup 10.3 onwards. You must set this configuration on all the backup hosts that are associated with the backup host pool.For example, if you configure the value to 512, then it means that 512 MB memory per volume is used as cache.
IGNORE_FILE_ACLS: Set this parameter in the
bp.conf
file to 1, to ignore the backup of file-level ACLs and user group information. Note that only the directory ACLs are backed up, the file-level ACLs are not backed up.During the restore operation, the Directory permissions are inherited. You can configure the parameters in the
bp.conf
file for backup hosts of NetBackup 10.3 onwards. Administrators must set this configuration on all the backup hosts that are associated with the backup host pool.
