All of your steps are fine but you don't have to swap the settings unless you are assuming the problem will be a software one and not hardware (not a bad assumption). Also if you are just setting it up I would recommend getting two of the same type of drive and get ghost. Then instead of regularly copying you could regularly ghost an image of your first drive to your second one. You could then maintain a number of ghosted images labelled by date. If your drive gets corrupted you will not need to swap things around you will simply have to boot to the ghost floppy and restore from the second drive to the first the last latest image that was not affected by whatever corrupted your system.

Personally I consider this method far superior to backup. If you have a CDRW you can also copy these images to it for a more permanent archive and depending upon the value of the data you probably should consider keeping a set of these CD's off site.

Hope this helps.
