Time machine with macbook questions.

[craptakular]

Hi,

I take delivery of a macbook in a few days & have been reading up on the joys of Timemachine.

How is timemachine gonna backup to my usb hdd when it isnt connected all the time? Will it throw a fit? or wait paciently in the background until its connected again?

Will I currupt the backup data if I eject the external usb while timemachine is updating? I ask this as the way I have read it timemachine works automagically in the background.

I read a blog somewhere where the guy had enabled timemachine to work over a network. Im assuming this is a bad idea over wireless considering the size of data involved?

Hope people can help.

Can I set time machine to manually update then? and stop it automagically doing it?

If I can, I assume some magic progress bar comes up? So I know not to switch off the external HDD.

Am I right in thinking that apart from going back in time to rescue a currupt/deleted file I could also use a snapshot of my HDD on say day 29 @ 9pm to restore my system to that state?
