NBU 7.6.0.3
i am having issues with backup performance and am looking at the default settings the vendor configured for our NBU server. in another thread, someone suggested that i have a look at max jobs per client, multiplexing, and STU (i still have to find what STU means :) ).
in my tape drive i found:
robot type: TLD
density: hcart2
max concurrent drives: 2 (i do have only 2 tape drives)
multiplexing is disabled but with a greyed out value of "1". fragment size is 1048575
with the above findings, if i want to increase backup performance should i change the values like enable multiplexing (my max jobs per client is now 4 from 99) ?
if i do change the data streams number, what should i do to make a configuration backup first of NBU in case the changes doesn't work and i want to restore the previous settings?
