If you do a lot of photog work, you can arrange another HD or parition, so that it is run as a serial backup type device and has no erasable structure on it as a standard HD has. It is under software control entirely. It is not a boot disk and so cannot in general be affected by boot sector virii. The best back up of a system, is as you suggested, another HD, it seems that tapes have fallen too far behind and are too slow. CD's or the soon to be ubiquitous DVD ROM write devices are the way to go.

I don't know to what extent the CD's writes are reliable/readable as you hear all kinds of things about bad CD's and needing to run at low speed and verifying to guarantee writes. MS Windows it appears, and the older hardrives have had some glitches with regards to the stream continuity needed to write a CD file with no interruptions. This is apparently improving.

Backup media, like Uninteruptable PS's, are not appreciated until that phase of the blue moon where it is seen to be needed in hindsight. Then it more than justifies the cost. I can testify to that. A UPS should be used. A disk mirror however implemented, for business is a bloody necessity. Of course I run under Linux which has no viruses. I have 60,000 fewer problems. My backup is I gzip, tar and ftp the files to a network machine.
