Backing up iTunes regularly/consistently

[LeperousDust]

I've got a LOT of music now, and i've been trying to keep it backed up with SyncToy, which works wonderfully in most cases for my backup needs apart from being unable to map to different drive letters (a name would be nice) at all. Anyway i can get over that by plugging in drives annoyingly in the right order ().

However SyncToy seems to think my MP3's have changed (rightly so) because they have a different accessed time (when i've played them funny enough), thus SyncToy wastes time copying files that aren't needed. How can i either make it look at the "created date" rather than the "accessed date"? Also it copies over loads of useless empty folders itunes keeps making, i've unticked most of them, but i can't tell it to just not ever copy anything from a sub folder...

Is there any other way to keep iTunes safe? I basically want all my music copied somewhere else and the iTunes DB so all my stats are kept up-to-date too

Ideas?
