One of the points I liked about Airport Extreme was the fact it had a USB port to add an external Hard Drive. Cool. Then came along Time Machine with Leopard and I thought even better I can now back up my MBP from anywhere to my 500GB external drive. Sadly that wasn't the case as TM didn't like network shares especially over wifi.

So as it stood I was plugging in to the usb HD from time-to-time to back up. Then a keynote speech later and Time capsule ... "my" idea is finally realised by Apple but wait a second ... I don't want to fork out for something I have albeit not in one shiny white box. (its one shiny box and a black western digital box). So realising that you can do it I did some google and came across the following hidden feature

Running that command from the Terminal will allow TM to see your network shares

Like i said though its hidden and hidden really equate to unsupported and could be dropped at any point/update. But for now its working fine.

Now if the restrictions on 802.11n can be lifted in the UK I could appreciate faster transfers.
