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

Betreff: Re: [ADSM-L] Exchange Backup with Flashcopy Manager EXTREMELY slow We 
have ~ 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....
