    Especially the recovery model and backup info. Or you can start here: http://www.sqlservercentral.com/stairway/73776/

  • The most common reason for uncontrolled log growth is being in Full Recovery mode without having any log backups.

    SET NOCOUNT ON

    USE 'YourDB'

    GO

    EXEC sp_helpdb 'YourDB'

    IF(SELECT CONVERT(int,value_in_use) FROM sys.configurations WHERE [name] = 'default trace enabled' ) = 1

    BEGIN

    , @base_tracefilename varchar(500)

    , @indx int;

    SELECT @curr_tracefilename = [path]

    FROM sys.traces

    WHERE is_default = 1;

    SET @curr_tracefilename = REVERSE(@curr_tracefilename);

    SELECT @indx = PATINDEX('%\%', @curr_tracefilename);

    SET @curr_tracefilename = REVERSE(@curr_tracefilename);

    SET @base_tracefilename = LEFT( @curr_tracefilename,LEN(@curr_tracefilename) - @indx) + '\log.trc' ;

    SELECT (DENSE_RANK() OVER(ORDER BY StartTime DESC))%2 AS [l1]

    FROM ::fn_trace_gettable( @base_tracefilename, default )

    WHERE EventClass >= 92

    AND EventClass <= 95

    ORDER BY StartTime DESC;
