Does that go for all TDP's or just Exchange, and another question, what is
the preferred method of retaining data created by TDP's for long term,
beyond standard retention settings?

Mark,

TDP for Exchange uses the TSM API to send and receive
data from the TSM Server. The TSM API does not support backup sets.
In order for TDPs to take advantage of backup sets, it will need
the TSM API to support backup sets.

The TSM BA client does not "understand" the data stream
that the TDPs generate, so it cannot be used to restore
the data either.

If you did not use TDP for Exchange for backup, i.e., you shut down your
Exchange server, did a file level backup of the Exchange files...
...then you can probably get it to work... but TDP for Exchange is
not involved and many people cannot afford shutting down the
Exchange server for backups.

It is a known requirement that customers would like the
TDPs to take advantage of backup sets.

Thanks,

Del
