Backing up Folders without some folders...;)

I am in a fix.......

I have to write a backup script to backup say Folder A.

Folder A contains n folders 1,2 ,3 .....n.

my script should copy A without folder 2 & 3.

Is there anyway I can do it without writing individual copy commands????

Please help....
