20TB of Data?  CD-R/DVD-R has a shelf life of about 5 to 10
years. Beyond that, your data will probably still be readable
but it's going to become hit-or-miss. Factory-stamped DVDs do
have a much longer shelf life, but that's not really relevant
here. Hard drives and magnetic tape should retain data reliably
for 10 to 20 years, making them a better option.
