The first image was copied using nbudr-hcart3-robot-tld-0 and the second using nbudr-hcart3-robot-tld-1.
that is the possible cause of using two tapes.
why?
I do not have and answer. But you can solve this by changing the "maximum number of partially full media" to 1 at the volume pool properties
04-05-2022 05:47 AM
yes.
If you put 1, netbackup will not ask for a new tape before the tape gets full, unless you use different retention or take the tape out of the library

There are now 40 tapes in the scratch pool. When Duplicate starts, one tape is moved to the DB_DATA pool. Then, can I change the value of "maximum number of partially full media" to '1' in DB_DATA pool?

yes.

I tried changing the "maximum concurrent write drives" value to 1. I think this was the wrong way. Thank you very much, I will try to solve it tomorrow.
