Hello guys, I know I should know the answer to this by now, but I don't so here's the question.... I need to get a new router and haven't set up time machine yet. Money is a little tight right now, so getting an airport extreme would be preferable and adding an external drive a little later. But is this the best way to go? I was thinking of going with a RAID 1 backup solution, like G-Safe. Or would you recommend just going with time capsule? Can I use the external drive for time machine backup's as well as NAS?
