Well, under Panther, it is now possible to back up your iDisk if you have automatic syncronization on. To do so, tell Backup you want to add a new item to backup. Navigate to ~/Library -> Mirrors -> SOMETHINGRANDOM -> YOUR_.MAC_USERNAME.dmg. Backup will happily burn this file to a CD, and you will have a complete backup of everything on your iDisk. Backup will remember the location in the future, so you only have to do this once.
