This is the huge flaw of CD-R, it's write once. I use 3.5" optical
disks, which run just like a regular random access disk and have a life
considered better than CD-R's, well in excess of 50 years. They are like
a bigger version of a minidisc, and of course higher capacity. That way
you don't keep producing throw away disks, but keep updating the same disks.
I consider a hard disk backup to be a convenience backup, but not
archival. It's magnetic media, the signal is dwindling from the moment
it's recorded. In analog this was a little less of a problem as the loss
of a small part of a recording did not kill the entire recording, not so
in digital.
I do use a external HD backup that's normally not turned on.
