Dan I am a .Mac user and the "Backup" module that comes in the collection of applications works wonderfully. I have two firewire 800 external drives and I have these scheduled to backup all the files at differing times of days, then the info. that pertains to the home directory is backed up to iDisk. The first backup is a full, the dailies are only the changed files. So far it has worked flawlessly.
