REM This is the file that we're going to backup from our local drive
SET source_dir="z:"

REM This is the location where the files will be copied to
REM on the external drive.
SET dest_dir="y:"

REM Set the log file name based on the current date.  This
REM will record the results from the robocopy command.
REM The typical format for the date command is:
REM Mon 11/09/2000
REM So, we are parsing the date by moving 4 characters back and 
REM copy 4 characters to get the 4-digit year, then we get the 
REM 2-digit month by moving 10 characters back and copying 2 
REM characters.  Finally, we get the day by moving 7 characters
REM back and copying 2 characters.
SET log_fname=%prefix%%date:~-4,4%%date:~-10,2%%date:~-7,2%.log
