I dont know about those others, but I use novastor because it lets me backup to my DLT drive in win9x. Most of the others mentioned here are for cdr-cdrw drives. I dont know about you, but I have 150gigs of data that I back up regularly and I dont feel like backing all that up to over 200 cds. 🙂 Just a couple of DLT tapes and I am set. Also, with novastor, you could make a bootdisk. This way, even if ALL is lost, you can boot with this special disc and restore everything from tape (if thats the medium you use, if not, then disregard all🙂 ).
