You can use any of them. These Are Sample For Use Date And DateTime In Backup Database:

SELECT 'TestDb' + '_'+CAST(CAST(GETDATE() AS datetime2) AS NVARCHAR(22))+ 
'_Log.trn';--TestDb_2019-09-28 13:54:42.54_Log.trn

SELECT 'TestDb' + '_'+CAST(CAST(GETDATE() AS DATE) AS NVARCHAR(MAX))+ 
'_Log.trn';--TestDb_2019-09-28_Log.trn

SELECT 'TestDb' + '_'+CAST(sysdatetime() as nvarchar(max))+ '_Log.trn';--TestDb_2019-09-28 13:54:42.5536994_Log.trn

SELECT 'TestDb'+'_' + convert(varchar(500),GETDATE(),120) + '_Log.trn';--TestDb_2019-09-28 13:54:42_Log.trn

SELECT 'TestDb'+'_' + convert(varchar(500),GETDATE(),112) + '_Log.trn';--TestDb_20190928_Log.trn

SELECT 'TestDb' + '_'+CAST(FORMAT(getdate(), N'yyyy-MM-ddThh:mm:ss') as nvarchar(max))+ '_Log.trn';--TestDb_2019-09-28T02:08:38_Log.trn
