Backing up to AirPort Disks
Airport Disks are not fast. Don’t expect blazing speeds: wired, I’ve seen a maximum of about 1.5MB/s.…Don’t expect miracles. This is an inexpensive solution, and it behaves like one.
Plus, since it’s over the network, you have to copy to a disk image, so you won’t have a backup that you can boot from.
