Buffalo HD-PHSXXU2-UC Quick Setup Manual page 7

Backup software for Windows PCs is available on your software disk,
included with your MiniStation. See your software CD for documentation
on installing and using that product. Many other commercial backup
solutions from third parties also work perfectly with the MiniStation.
Apple offers a Backup Utility to OS X users who have purchased a .Mac
account. This is not a Buffalo product, but if you have .Mac, the following
directions may be helpful:
Connect the MiniStation hard drive
to your Mac and make sure it is
mounted on the desktop.
From your Applications folder, open
the application Backup.
By default, the user idisk is selected
as the backup destination. To change
this to the MiniStation, click the Set
button and then the Create button.
