AEBS and external Hard disk

[Turbo-G]

Guys,

I have an Apple Extreme Base Station which provides me with all my wifi needs. However, I am looking at buying a rMBP to compliment my 2010 iMac... therefore I will need a backup solution.

I currently backup to a 2TB WD disk, connected solely to my iMac for Time Machine purposes.

Am I right in thinking I can connect a spare external hard drive via USB to the AEBS downstairs, and use Time Machine to backup my rMBP to the newly network attached hard disk over the air?

Thanks,

Grant

Coolio. Now to decide, top spec 13" rMBP or lower 15". Swaying towards the 15" for the quad core CPU and dedicated graphics for only £100 more.

I don't really want to replace the AEBS with a TC as I haven't had it all that long.

The laptop will predominantly be used for general use, plus aperture and a few other apps, mainly at home but occasionally remotely.

My iMac is never shut down, always left in a 'sleep' state. Presumably my MBP would be able to access the USB attached WD drive via 'sharing' wirelessly to make a Time Machine backup?

Sounds good if so, not sure how this can be any more reliable than attaching a drive to the AEBS though?
