Hi,

we're experiencing slow performance while backing up a 1,5 TByte MS SQL 2008R2
database with the TDP SQL Agent 6.3. As for DR-scenarios, we're doing legacy
backups only. The actual speed is usually around 20 MByte/s, backups go to
LTO-5 tape directly. The backup stream has to pass through 3 different
firewalls, so we're not quite sure where the bottle neck is located, MS SQL
API, TDP Agent or IP-firewall (SAN-Storage and TSM-Server should outperform
everything else).

Maybe someone can share his performance values with me. Any hints are welcome.


Regards,


   Sven
