Tune Backup provides a easy-to-use backup solution for your iTunes library. Simply tell Tune Backup where your iTunes Library.xml file is, where you would like your backed up files to go, and click the sync button. Your library will be incrementally synced. This means that if you sync your library in morning, add a song later in the day, and sync again at night, only the new file will be copied.

Requires iTunes 7.1
