Thanks Del for your reply.
In this case customer has fully migrated the data from Exchange 2007 to 2010.
No migration activity is going on.
Further bkp process tooks approx 2 hrs for integrity check, rest time window
for backup (out of 25 hrs of total backup window)
Please advice...
Thanks,
Sachin.
