Here in Sao Paulo we have a network maintained by friends. When we meet, we
all r-sync our secondary backups and when we get home, r-sync the primary
backups. We have many data repositories in safe harbour, and we would be

The bitsavers archive is 267 Gbytes.
So at 4.7G per DVD, it comes out to almost 60 DVD's.
I would suggest using Blue-Ray media, at 25GB or 50GB per disk. We're then
down to 6 or 11 platters.
