Hi. You can use your Leopard install dvd to restore a time machine
backup. However, that backup is not bootable itself. What I would
suggest you do, assuming your external drive is large enough, is to
partition it in to two parts. Use one of these for time machine, and
use the other one to make a bootable clone of your drive. In an
emergency situation, you can get things up and running much faster
with a bootable clone. You can use something like carbon copy cloner
to do this.

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

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
