one touch backups to external hard drives

[slag]

I have a few computers at home I'd like to back up regularly over ethernet or usb 2.0 to an external drive.

Do any of the products support backups from multiple sources (computers) or only one computer per external drive?

What are the best consumer grade solutions for doing this?

Take a look at SyncToy from Microsoft.

This will.

Edit: It used to. I see they've changed the name of the software. Read through and make sure it still does.
