Wireless backup storage from Storage Appliance Corp.

The Clickfree Wireless Backup external drive communicates with PCs and Macs over 802.11n WiFi, and we can easily back up our data.

You can connect up to several machines to the device in-house, whatever important data you have, thanks to Backuplink technology, you can secure them with one click. There are no compromises with operating systems either, we can safely use them under Windows and Mac OSX as well. If we're paranoid, we can even hide the device behind drywall or in a closet, so unauthorized people can't access our data, but thanks to wireless technology, we can still place files on the device as if we were just in an action crime movie.

The 500GB Clickfree Wireless Backup costs $ 179, while the 1TB version costs $ 249.
