Hi Steve,

You were most likely using legacy (streaming) backups with
Exchange 2007. Exchange 2010 uses VSS backups because Microsoft
dropped the legacy backup method starting with Exchange 2010.
These two methods of backup use a very different API.

The four backup types have not changed, however:
  - Full = back up database and logs, truncate logs
  - Copy = back up database and logs, do NOT truncate logs
  - Incremental = back up logs, truncate logs
  - Differential = back up logs, do NOT truncate logs

>From a Data Protection for Exchange perspective
the backup operation and log file truncation behavior
has not changed.

With VSS backups, Data Protection for Exchange
does not tell Exchange to truncate the logs,
it simply reports that the backup was successful.
>From that report of a successful backup, Exchange will
schedule the log truncation at the most opportune time,
depending on DAG database replication health and status.

You should see an indication in the Windows Event Log
that the backup was completed successfully and
another one about log truncation.

If you continue to see problems, you could open
a PMR. The TSM support team will most likely ask
you to also get Microsoft involved since these
log truncation issues usually end up being something
in Exchange itself.

Thanks,

Del
