Hi Jeff,
In order to get a consistent backup of a SQL Server database,
you must use a tool that is integrated with SQL Server.
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.
Thanks,
Del
