Both tar and gzip trade complexity for something (combinding files into

corruption for another. This is more finnicky for compression tools, so
uncompressed tape archives stand a somewhat better chance of recovery
beyond a bad spot (eg. due to media failure).

Hmmmm... I wonder if gnu tar could be fiddled with to add an option to
compress each file first, then wrap the compressed/encrypted files in the
tar archive. This could mean losing only one file, instead of the whole
archive if there is a flipped bit.
