Just got a new iMac and want to get into the habbit of backing things up--now with Time Machine this should be easy. Please keep in mind that I have a maximum budget of £100. :-( Now, since I also have a Macbook here with me, what I would prefer to do is to have a externall HDD plugged into my router so it is available all over the network. However, I am not too clued up on NAS--and I believe it has problems with Time Machine, correct? If NAS would not be a good idea, I would like to take advantage of the iMac's FW800 port. However, are there any good HDD's out there, with my budget in mind, which offer this? If not, then I would use USB. However, I wouldn't want it to be required to be plugged into a socket. Not too much to ask -/ ), anyone have any ideas, or preferences, into which option would be best for me, and perhaps reccomend one or two external HDD's? Thank you very much, Virtual.
