Backup your iTunes Library
Ah, now this is a very nice new feature in iTunes 7.
There's more information here.
I've noticed a bit more of a trend in this direction recently: for applications to incorporate backup options for their own data. I think it's quite a good idea, because they often have a better idea of what needs backing up, how often, and in what way, than a more general "copy the files" backup. A couple of other packages I use which have two very different, but both very good, backup strategies built-in are the excellent accounting package MYOB and Apple's Aperture.
So my photos, my accounts and my music now all have their own backups in addition to the general disk-cloning that I do from time to time with SuperDuper. Good for one's peace of mind. I shall now go to bed and sleep soundly.

The gites that we rented in the little village of Gaillagos.
This year, for the first time, I could pay for the replacement online, and it was posted to me. Very convenient. The details are also printed rather than handwritten, and are rather more legible than last year's one!
