It backs up everything, but not in a bootable format. I haven't checked
but I'm assuming that to do a full restore you would need to wipe the
new drive and do a fresh install of 10.5 and then use Time Machine to
bring everything back to whatever point in time you wanted. That's
assuming so catastrophic loss like you hard drive dying or a stolen laptop.

Hi Chris.
I'll get an external hard disc very soon which I'll use together with
Time Machine.
If I choose to make a backup of the whole system, can I then boot the
system up from my external hard disc? In other words: Does Time
Machine backs up the whole operating system which I can restore if the
whole system crash?
Best regards Søren.

Subject: Re: Time Machine.
Format? Your drive should already be formatted. The first backup will
take quite a while as Time Machine will be copying pretty much the
entire contents of your hard drive to the external drive. USB is also
much slower than Firewire so that will contribute to dragging out the
first backup process. Most of the stats I've seen for USB2 show
throughput pegging at about 10MB/s while FW400 pegs at about 30MB/s.
I'm sure with lots of little files both of those rates drop. So if we
assume you have maybe 75GB of stuff to backup and you get maybe
7.5MB/s that would be 10,000 seconds or about 2.8 hours.

Hi,
Can anyone advise how long a 250GB USB external drive should take to
format
using Time Machine? It's been running for about 40 Minutes. Voiceover
doesn't appear to interact with the window that is open, all I can
get out
of it is "busy".
Thanks in advance
