Thanks for the reply Del. Looks like i'll stick with the TDP backup for the time being.

In the case of snapshots, you must use a tool that knows how to work with SQL Server snapshots. SQL Server has two snapshot mechanisms, one through the VDI interface and the other through VSS. As a matter of fact, the SQL Server VSS Writer implementation calls VDI snapshot APIs under the covers. TSM does support SQL Server snapshots using VSS. You will need Data Protection for SQL 5.5 (or later) along with the TSM for Copy Services license module in order to perform SQL Server VSS snapshots with TSM. You can attempt to use the LVSA, but I am not sure Microsoft will officially support you if you cannot get your SQL Server database into a consistent state.
