I take it you mean you'd like to make a back-up copy of the USB hard disk, for safe-keeping? Do you have another external drive to copy the music onto, or did you have something else in mind?
To do a disk-to-disk copy you could use tools supplied with the OS by issuing commands in the Terminal program but from your post I gather you would prefer something easier to work with.
The most user-friendly way to do it is probably to use a directory synchronisation tool. Those tools are designed to keep a back-up disk in sync with what's on a master disk. The one I use is Destek Folder Sync, which I find reliable and easy to use. Searching for "OS X folder sync" will help you find other options.
By the way: don't forget to keep your back-up drive somewhere physically separate from your Mac Mini, unless you have another back-up mechanism as well.
