Enabling tracing

Diagnostic tracing is disabled by default. When investigating a problem, Quest Technical Support might ask you to enable tracing on the relevant NetVault Backup machines to capture diagnostic information about the error condition. This information helps in determining the source of error condition. Once the traces are enabled for the server, warning is displayed as Diagnostics in the Header Pane of NetVault Backup.

 
* 
IMPORTANT: Tracing can affect performance of the application and generate large amounts of data on the server and client machines. You should only enable tracing when requested by Quest Technical Support, and disable this option after the issue is resolved.

By default, the trace container directory is created under the NetVault Backup installation directory. You can modify the default settings to specify a new location for the container directory. When tracing is enabled, a session directory is created under the container directory; all trace files generated during the session reside in this directory.
