Feel like my second home at the mo....

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 Library.

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.

I have gone through all settings on the ESL, cannot see anything, found nothing to research, but I cannot sustain this sort of throughput!

Yet, I cannot quite understand why this is happening.

Any ideas welcome!

Simon
