    Please take time and read through the Perf Tuning guide.
    Go through the exercise to test disk read speed with bpbkar followed by a network copy, such as ftp. Also see buffer tuning section, but only change buffers once you have analysed default settings in bptm log (details in the Tuning guide).

    A quick win is normally to increase max jobs per client to +- 4, allow multiple data streams in policy attribute (assuming that Backup Selection is ALL_LOCAL_DRIVES or multiple filesystems), increase MPX value in STU to 4 as well as MPX of 4 in Policy schedule.

    Hope this helps.

    PS: Updated license keys are free if NBU maintenance is up to date.
