Ideally one could find a good used DLT tape drive and buy 40Gb tapes
for $50 each. I just discovered GNU/Linux has a utility called
'split' which can divide a large file into DVD size chunks. This
worked on a 30Gb file I wanted to keep, just not on precious hard
disk space:
$ split -b 4400m rf_data
will create files xaa xab xac each 4,613,734,400 byte, divisible
by 8 for an even boundary on complex data.
A 30Gb file fit on 7 DVD's, using an inexpensive writer and
disk prices are getting lower all the time. Time consuming but
cheap and works.
The file is easily reconstructed with
$ cat xaa xab xac xad xae xaf xag > rf_data
or they will play from the split files.
