Example code with the date format appended to the end of the folder that you are backing up.

E.G E:\CapitalCharge - 240503\

code:
$DATE = SubStr( @DATE, 9, 2 ) + SubStr( @DATE, 6, 2 ) + SubStr( @DATE, 1, 4 )
MD "E:\CapitalCharge - $DATE"
Copy "C:\CapitalCharge" "E:\CapitalCharge - $DATE" /h
This may be of some help.

Thanks
