    In-Depth Troubleshooting Guide for Status 84: http://www.symantec.com/docs/TECH43243 
    (Old, but still valid)

    As per above TN - NBU relies on OS for I/O, so, all troubleshooting needs to be done at Os level.

    See manual for NBU and OS-related logs to be enabled for troubleshooting.

    Be aware that status 84 is a generic write failure. It's often related to bad tape drives, but a fragile SAN infrastructure could also generate status 84's.

    Inspect syslog or event log for SCSI sense codes:

    If you find some - post them.

    How to collect the log?

    Have you tried to go through links in the replies to your post?

    The Status 84 In-Depth Troubleshooting Guide tells you to enable bptm log on media server. 
    You enable the log by creating the folder.

    OS log is Windows Event Viewer System log.
