Steve, that is very interesting. In my current massive ripping project, I generate (at 192/24) about 4GB per hour - about 3600 times less than CERN. To me that is a surprisingly small difference. I have similar concerns about data storage and redundancy and safety - since my project so far has taken 3 years and generated about 15TB of data. I have streamlined the process some and should have about 30TB when I am finished about 2 years from now. However, that is a lot of person hours of labor to lose. So right now I use a big NAS RAID5 system with two extra unused drives and two different backups for the data. I have not done off site storage, but we just rented a big safe deposit box and I am going to put another set of completed drives there. I investigated on-line storage, but with 15TB, the upload time and cost seems pretty high.
Haven't considered tape.
