Hello Grigori,

"Officially" speaking, you do need at least a TSM Server
at the 6.1 level to support a TSM 6.4 B-A Client:

     http://www-01.ibm.com/support/docview.wss?uid=swg21053218

Data Protection for Exchange 6.4 requires a TSM 6.4 B-A Client
(and will install it automatically when configuring
Data Protection for Exchange 6.4 using the Configuration Wizard.)

There is a large "value-add" for Exchange Server 2010 DAG environments
by using Data Protection for Exchange 6.4, so your decision
is a good one. In the mean time, you can still protect your
Exchange Server 2010 DAG environments using the older version of
Data Protection for Exchange.

Thanks,

Del
