My choice: two different external USB drives, one of which is stored away from the comp and one attached to it - albeit powered-down while I don't need. My backup method: everytime I install something or create something, I fire up the external drive, hit "ICE Mirror" that makes a mirror image of the whole of Poser installation and a special "Renders" folders that contains new work. Once done (usually only takes a few seconds), I power down the external drive. Quick and clean. Then once a week, I do the same to the other external drive - in effect having two different backups on two different external drives. This I do because there exists the slight possibility that a power surge kills not only the main hd of the comp, but also the attached external drive. The data is backed up elsewhere, so I essentially lose only a week's worth in the absolute worst-case scenario (well to be honest my house could burn down to a charred pile of rubbish, but I doubt my main concerns would be Poser in such an event anyway). I, too, absolutely HATE to hassle with CDs and DVDs. ICE Mirror is also very easy to use and is free (you can get it by googling it).
