To measure disk I/O using the bpbkar command

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

   • Linux/UNIX:

     /usr/openv/netbackup/logs/bpbkar

   • Windows:

     install_path\NetBackup\logs\bpbkar

2. Set the logging level to 1.

3. Enter the following:

   • Linux/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:

   • Linux/UNIX:

     The start time is shown in the bpbkar initialize entry in the bpbkar log. The end time is shown in the entry bpbkar main: INF - Client completed sending data for backup. The elapse time is the time duration between the start time and the end time.

     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". For example:

     Elapsed time: 1622 secs 59370573 bps
