Two are enough for rotation (the third is the drive of the computer). I
still bet that 2 times 100 € for 2 times 500 GB of usb disks is cheaper
in the long run than a burner plus all those DVDs. On top of that you'll
save many hours of your and your computer's (up)time.
Of course it depends on your level of paranoia of how many copies of
your data you consider 'save enough for your needs'. However, for the
same level of paranoia, the number of copies required on hard disk is
far less than on optical media.
It also depends on the amount of data to be backed up.
YMMV,
Johannes
