SQL Server 2012 :: Spool Backup Command Result To A Text File

I am running backups on SQL Sever express and I take backups via the batch file executing the TSQL as below. This works perfectly fine, I just need to be able to spool out the backup completion log. What TSQL command can I use to do that?

My batch file looks like this:

@echo off
sqlcmd -S SERVER01 -E -i H:master_scriptsTOM_FAM_log.sql

Which will the call the TOM_FAM_log.sql :

DECLARE @name VARCHAR(50) -- database name
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @fileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
SET @path = 'H:BackupTOM_FAM'

[Code] ....

Usually if we schedule the backups using the maintenance plan, we can chose reporting options that can spool the result of the backup to a text file. What is the T-SQL for the spool report to a text file.

This option produces a file that writes logs with the details I posted below. I would like to do the same or similar using T-SQL in my code.
