Backing your music library using iTunes can be acheived easily. The One Digital Life blog has a nice tutorial on how to do that.
The method is simple but clever. The author sets iTunes to burn data CDs or DVDs (iTunes automatically sets up multiple sessions if there’s not enough space on one disc), then sets a Smart Playlist to keep tracks of all music added to iTunes after the date of the last backup. Next time you decide to backup, you can simply burn your Smart Playlist.
