Instructions

NetWorker sends messages to two types of logs. Plain text log files that are saved with the .log extension and unrendered log files that are saved with the .raw extension. The .log files and the messages that appear in NMC use the locale setting of the service that generates the log message. To view the contents of .log files, use any text editor. Before you can view .raw files in a text editor, render the .raw file into the locale of the local machine. You can manually render the raw log files or configure NetWorker to render the log files at runtime.

NetWorker Client Log Files:
 

Component File name and default location Description
NetWorker Client daemons
  • Linux/UNIX: /nsr/logs/daemon.raw
  • Windows: C:\Program Files\EMC NetWorker\nsr\logs\daemon.raw /nsr/logs/daemon.raw
 Main NetWorker log file.
Use the nsr_render_log program to view the contents of the log file.
User log C:\Program Files\EMC NetWorker
\logs\networkr.raw		 For Windows only, contains a record of every file that was part of an attempted manual backup or recovery operation that is started by the NetWorker User program. Subsequent manual backup or recover operations overwrite the file. Use the nsr_render_log program to view the contents of the log file.
Windows Bare Metal Recovery (BMR) The following files in the X:\Program Files\EMC NetWorker\nsr\logs\ directory:
ossr_director.raw		 Contains the recovery workflow of the DISASTER_RECOVERY:\ and any
errors that are related to recovering the save set files or Windows ASR writer errors. Use the nsr_render_log program to view the contents of the log file.
... recover.log  Contains the output that is generated by the NetWorker recover.exe program and error messages that are related to critical volume data recovery.
... winPE_wizard.log Contains workflow information that is related to the NetWorker BMR wizard
user interface.
... winpe_nw_support.raw Contains output from the winpe_nw_support.dll library. The output provides information about communications between the NetWorker BMR wizard and the NetWorker Server. Use the nsr_render_log program to view the contents of the log file.
... winpe_os_support.log Contains output information that is related to Microsoft native API calls.
CloudBoost - NetWorker Client The following log files in the
/nsr/logs/cloudboost directory:

MagFS.log.ERROR.date-timestamp.pid.txt
MagFS.log.FATAL.date-timestamp.pid.txt
MagFS.log.INFO.date-timestamp.pid.tx		 These files appear on a client direct-enabled NetWorker Client and contain information about data stored on a CloudBoost device. The severity of the message determines which log file that error message is written to. The maximum size of the log files is 100 MB.

Before a client direct backup, the save process checks the size of the file. When the maximum size is reached, save starts an automatic trimming mechanism, which renames and compresses the log file. The maximum number of versions for a file is 10. When the number of renamed log files reaches the maximum version value, NetWorker removes the oldest log when a new version of the log file is created.

NOTE: The Troubleshooting manual backups section of the NetWorker Administration Guide describes how to use the CB_LOG_DIR_LOCATION environment variable to change the default log file location.
CloudBoost - CloudBoost Appliance The following log files in the /nsr/logs/
cloudboost directory:

MagFS.log.ERROR.date-timestamp.pid.txt
MagFS.log.FATAL.date-timestamp.pid.txt
MagFS.log.INFO.date-timestamp.pid.txt		 These files appear on the CloudBoost appliance and contain information about operations that are performed on a CloudBoost device. The severity of the message determines which log file that error message is written to. The maximum size of the log files is 100 MB.

When the maximum size is reached, the nsrmmd process starts an automatic trimming mechanism, which renames and compresses the log file. The maximum number of versions for a file is 10. When the number of renamed log files reaches the maximum version value, NetWorker removes the oldest log when a new version of the log file is created.
