Generating a diagnostic file for troubleshooting Backup Exec

Last published : Apr 02, 2026
Backup Exec includes a diagnostic application (Bediag.exe) that gathers information about a Windows computer for troubleshooting purposes. This application can be run from within Backup Exec or it can be run from a command line. This application can be run for a local server or a remote server. You can run diagnostics on a remote Backup Exec server if Backup Exec is installed on the remote server and the Backup Exec services are running.
The Bediag application collects the following types of information:
  • Account groups, account privileges, and environment settings.
  • Backup Exec software version and registry information, Backup Exec agent listing, Windows version information, SCSI hardware configuration, SQL Server information, Driver services information, and Windows Services information.
