Much more serious than re-encrypting every so often is moving entire
formatted information systems from one technology to another.
Anyone still read WANG 8" Floppy WP documents? Even assuming you could
find which disk the specific information in on, it's costly. Really,
since we have just started the move to putting records on line, the
entire issue of how accessable those will be in 100 years has been
completely hand waved away. Yes, I know there are technical means, but
will there be money and staff to do it? Paper archives, on the other
hand, when they havn't been burned or submerged or recycled, usually are
fairly easy to locate and read a record in, but more to the point, the
technology is still understood and readily available.
