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.

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
