Another thought is to get with the 2000's and backup to disk! ;).

wondering if the drive is waiting for buffers to become full before writing.
What are you NUMBER_DATA_BUFFERS and SIZE_DATA_BUFFERS

I have a crazy situation here, so wonder if anyone with HP G3 ESL experience
can help.
7.5 environment, separate Media Server that can backup to LTO4 Library and new
ESL Library.
Problem. Backups over the LAN throughput is really bad going to the LTO5

To give you an idea, 20 hours to backup 100GB.
I cancel the job, revert backup policy to the LTO4 library, same media server
and backups of the same capacity done in 2 hours.
Someone check my math, but 100gb in 2 hours, 50gb/hour, 853mb/hour, or
14mb/sec. I wonder if the LTO4 is able to slow

something wrong there. Maybe shut that one down to see if it has an issue.

With a 10x performance difference between backing up to the LTO4 drives and the
LTO5 drives, I'd suggest checking the fibre path from the server to the tape
drive in the LTO4 library and comparing it to the LTO5 library. You might want
to check port errors at the switch.
I have my doubts this
