I completely blame myself on this so don't take it the wrong way, but the Time Capsule + Macbook Air is a horrible combination. I bought a Time Capsule and new 13" Macbook Air last month but recently decided to replace the 13" Air with an 11". When I got the 11" home I tried doing a Time Machine restore but after 6hrs it hardly put a dent in the restoration. The problems I encountered was: 1) Air is WiFi only. Yes, theres an ethernet adapter but its $30 and limited to USB2 so its pretty slow also 2) Time Capsule is built on old technology, meaning no FireWire or Thunderbolt ports. It does have USB2 but... 3) Time Capsule USB2 port doesn't allow you to access the internal data. I'm kicking myself because Ive been teetering on getting an Airport Extreme + HDD combo for a while and I was given a HUGE warning because the initial Time Machine backup took 2days! So if it takes that long to put data on, why would it be any faster to get data out. The obvious answer is to return the Time Capsule but I waited too long (2days ironically). And now I'm going to buy an external drive to use for Time Machine instead because if I need a mission critical restore then the Time Capsule is UNRELIABLE.
