In this case I make a backup image with Norton Ghost then I restore when/where I need. I get everything very easy and unchanged. Acronis Image also works good. But I prefer to use Norton Ghost.
I have had Seagate 640GB From ebuyer via rboffers http://www.rboffers.com/computers/seagate-expansion-640gb-portable-hard-drive-hi-speed-usb-59-99-ebuyer-72916.html/. I use it only to store temporary backups which I need to update every week. YEah very easy super fast.
