I keep my itunes library on an external, bus powered hard drive. I want to keep a backup of my music. Nothing fancy, I just want to copy the files to another external drive.
The easiest way to do it is w/ the copy command. Mine looks like this:
cp -Rnv "/Volumes/tre/iTunes Music" "/Volumes/gigante/tre_backup"
R: recursive
n: copy only when the SOURCE file is newer than the destination file or when the destination file is missing
v: verbose
