Hi
Environment:
NBU 5.1 MP5 Master Plus many SAN SSO Media Servers Win2k3 SP2
Problem: Mail Backups of Information Store using LTO4 SL500 are taking 4 1/2 hours extra to backup compared to LTO3.

Has anyone got any exposure to Ex2k3 / LTO4 / NBU5.1 Online Exchange Backups? Checking the Exadmin Guide showed little to no help, and we are backing up approx 1TB of Exchange Data.

Job would start at 6:30 and normally finish at 10:30. Now, its finishing at 3:00am.
Same configuration is in place (ie: 3 streams to 3 different drives) and all part of the same fabric, apart from being in a different building.

Any advice appreciated.

Regards

Simon
