Auto-Backup/Auto-Sync app

Very quick ideation here just to get the idea down somewhere. I’ll come back later and expand on this idea.

Basically, the gist is to have an application to back up my iTunes library, which I have residing on an external hard drive that I carry with me to and from work. I currently don’t really make backups too often, and I’d like to have a way to automatically create a disk image when I plug in the drive. The upshot is that *theoretically* I should be able to use the library at home even if my hard drive isn’t plugged in.
