Accelerator messages in the NDMP backup job details log

This topic provides explanations of some specific messages that appear in an NDMP job details log when Accelerator for NDMP is enabled.

The messages in the NetBackup job details include messages that are generated directly from the filer. To find the messages from the filer, look for the NDMP host name in the message following the PID number as in the following example:

mm/dd/yyy hh:mm:ss - Info ndmpagent (pid=10780) [NDMP_host_name]: 
Filetransfer: Transferred 146841088 bytes in 2.855 seconds 
throughput of 50231.929 KB/s

Note:

Some messages that are generated directly from the filer, such as filer volume is full, may require your immediate attention. Consult the documentation for the filer to determine how to resolve any issues with the filer that are indicated by a message from the filer in the job details.

First Accelerator-enabled full backup

Messages similar to the following appear in the job details log for the first full NDMP backup that uses Accelerator for NDMP.

 mm/dd/yyyy 1:28:47 PM - Info bpbrm(pid=3824) accelerator enabled
...
...
 mm/dd/yyyy 1:28:53 PM - Info ndmpagent(pid=10556) accelerator 
optimization is <off>, unable to locate accelerator tracklog
...
...
 mm/dd/yyyy 1:29:05 PM - Info ndmpagent(pid=10556) accelerator sent 
1310720 bytes out of 1310720 bytes to server, optimization 0.0%

Note the following items about messages for the first Accelerator-enabled full backup:

  • accelerator enabled

    This message indicates that the Accelerator option is being used.

  • accelerator optimization is <off>, unable to locate accelerator tracklog

    Because this is the first full backup, NetBackup creates a new track log. More information about the locations of the track log is available:

    See NetBackup logs for Accelerator for NDMP.

  • accelerator sent 1310720 bytes out of 1310720 bytes to server, optimization 0.0%

    Because this is the first full backup, all data is backed up and no optimization occurs yet.

Subsequent Accelerator-enabled incremental backup

Messages similar to the following appear in the job details log for subsequent incremental NDMP backups that use Accelerator for NDMP.

 mm/dd/yyyy 2:01:58 PM - Info ndmpagent(pid=8652) accelerator 
optimization is <on>
 mm/dd/yyyy 2:01:58 PM - Info ndmpagent(pid=8652) BASE_DATE will be 
used to determine changed files for accelerator
 mm/dd/yyyy 2:01:58 PM - Info ndmpagent(pid=8652) please ignore 
references to LEVEL in future messages
...
...
 mm/dd/yyyy 2:14:14 PM - Info ndmpagent(pid=10044) accelerator sent 
1104896 bytes out of 100310720 bytes to server, optimization 15.7%

Note the following items about messages for the subsequent incremental accelerator backups:

  • accelerator optimization is <on>

    This message indicates that a track log exists and the backup shall perform with the Accelerator option.

  • BASE_DATE will be used to determine changed files for accelerator and please ignore references to LEVEL in future messages

    These messages are a reminder that Accelerator for NDMP uses BASE_DATE and DUMP_DATE rather than dump levels to identify changed data. Messages that refer to dump levels come from the filer. However, the message to ignore references to LEVEL also appears in the job detail logs as a reminder that dump levels are not used with Accelerator for NDMP.

  • accelerator sent 1104896 bytes out of 100310720 bytes to server, optimization 15.7%

    This message provides the amount of data that was sent to the server and the percentage of optimization that was realized.

Next Accelerator-enabled full backups

Messages similar to the following appear in the job details log for subsequent full NDMP backups that use Accelerator for NDMP.

 mm/dd/yyyy 2:01:58 PM - Info ndmpagent(pid=8652) accelerator 
optimization is <on>
 mm/dd/yyyy 2:01:58 PM - Info ndmpagent(pid=8652) BASE_DATE will be 
used to determine changed files for accelerator
 mm/dd/yyyy 2:01:58 PM - Info ndmpagent(pid=8652) please ignore 
references to LEVEL in future messages
...
...
 mm/dd/yyyy 1:40:27 PM - Info ndmpagent(pid=12244) accelerator sent 
887296 bytes out of 1159725056 bytes to server, optimization 99.9%

Note the following items about messages for the subsequent incremental accelerator backups:

  • accelerator optimization is <on>

    This message indicates that a track log exists and the backup shall perform with the Accelerator option.

  • BASE_DATE will be used to determine changed files for accelerator and please ignore references to LEVEL in future messages

    These messages are a reminder that Accelerator for NDMP uses BASE_DATE and DUMP_DATE rather than dump levels to identify changed data. Messages that refer to dump levels come from the filer. However, the message to ignore references to LEVEL also appears in the job detail logs as a reminder that dump levels are not used with Accelerator for NDMP.

  • accelerator sent 887296 bytes out of 1159725056 bytes to server, optimization 99.9%

    This message provides the amount of data sent to the server and the percentage of optimization that was realized.

Accelerator-enabled forced rescan full backup

Messages similar to the following appear in the job details log for full NDMP backups that use Accelerator for NDMP with the Accelerator forced rescan option.

 mm/dd/yyyy 2:13:43 PM - Info bpbrm(pid=8628) Accelerator enabled 
backup with "Accelerator forced rescan", all data will be scanned and 
processed.Backup time will be longer than a normal Accelerator enabled 
backup.
...
...
 mm/dd/yyyy 2:13:46 PM - Info ndmpagent(pid=10044) accelerator 
optimization is <on> but 'forced rescan' is enabled

Note the following items about messages for accelerator forced rescan backups:

  • Accelerator enabled backup with "Accelerator forced rescan", all data will be scanned and processed. Backup time will be longer than a normal Accelerator enabled backup and accelerator optimization is <on> but 'forced rescan' is enabled

    These messages indicate that a forced rescan is enabled and that the job shall run longer than a normal Accelerator full backup. Though accelerator optimization is on, the job may run slightly longer than accelerated full backups.
