Hi John,
        I had a similar situation with Exchange 2010 TSM DP backups and the reason \
was the VM  had been Vmotioned from one ESX to another. Lan speed went from 1Gbs to \
100Gbs. You might want to check this.

Thank you Chavdar Cholev and Jeanne Bruno for sharing. I forgot to tell, we do skip \
the integrity check, and there are only passive Databases on the server. Are your \
backups going to TSM server or to a local storage? Im interested either way.

Best Regards,
John

2TB full exchange backup and it takes ~ 20 hours. There is exch db consistency check \
before backup which takes considerable amount of time. It can be switched off... but \
it is not recommnded....
