More than a mere backup, Time Machine makes an up-to-date copy of
everything on your Mac - digital photos, music, movies, TV shows, and
documents - so you can go back in time to recover anything.

You can start using Time Machine in seconds. The first time you attach
an external drive to your Mac, Time Machine asks if you'd like to use
that drive as your backup. Say yes and Time Machine takes care of
everything else. Automatically. In the background. You'll never have
to worry about backing up again. Back up everything. It is all built
in to OSX 10.5.

Time Machine keeps an up-to-date copy of everything on your Mac. That
includes system files, applications, accounts, preferences, music,
photos, movies, and documents. But what makes Time Machine different
from other backup applications is that it not only keeps a spare copy
of every file, it remembers how your system looked on any given day -
so you can revisit your Mac as it appeared in the past.

You can't do that with eCS. When eCS screws up, and it will no matter
who tells you it won't, you go back to scratch and more than likely
you will lose everything and all the work you did before it failed on
you. OSX doesn't fail. It is solid as a rock. And it comes with
Time Machine. Buy an external hard drive, plug it in via USB or
Firewire, and never worry again. Ever.

Enter the Time Machine browser in search of your long-lost files and
you see exactly how your computer looked on the dates you're browsing.
Select a specific date, let Time Machine find your most recent
changes, or do a Spotlight search to find exactly what you're looking
for. Once you do, click Restore and Time Machine brings it back to the
present. Time Machine restores individual files, complete folders, or
your entire computer - putting everything back the way it was and
where it should be.

Effortless meets wireless.

With a hard disk connected to your AirPort Extreme Base Station, all
the Macs in your house can use Time Machine to back up wirelessly.
Simply select your AirPort Disk as the backup disk for each computer
and the whole family can enjoy the benefits of Time Machine.

Preferential treatment.

Customize Time Machine by modifying the following behaviors in System
Preferences:

* Backup disk. Change the drive or volume you're backing up to. Or
back up to a Mac OS X Server computer.
* Do not back up. By default, Time Machine backs up your entire
system. But you can also select items you'd rather not back up.
* Encrypt backup data. Turn on encryption to store your backup
securely.
* Backup storage time limits. Manage older backups so your backup
drive doesn't fill up.
