Measuring disk performance with bpbkar

Use this procedure.

To measure disk I/O using bpbkar

  1. Turn on the legacy bpbkar log by ensuring that the bpbkar directory exists.

    UNIX

    /usr/openv/netbackup/logs/bpbkar

    Windows

    install_path\NetBackup\logs\bpbkar

  2. Set logging level to 1.

  3. Enter the following:

    UNIX

    /usr/openv/netbackup/bin/bpbkar -nocont -dt 0 -nofileinfo
  -nokeepalives file system > /dev/null

    Where file system is the path being backed up.

    Windows

    install_path\NetBackup\bin\bpbkar32 -nocont X:\ > NUL

    Where X:\ is the path being backed up.

  4. Check how long it took NetBackup to move the data from the client disk:

    UNIX: The start time is the first PrintFile entry in the bpbkar log. The end time is the entry "Client completed sending data for backup." The amount of data is given in the entry "Total Size."

    Windows: Check the bpbkar log for the entry "Elapsed time."
