One of my hobbies is writing, a practice in which I have been engaged
since the late 1980s.  For personal reasons, until very recently, I
did all of my writing in plain text files, all around 20-30k, and kept
all my archives in pkzip, then zip/unzip format.  From August through
December, 1999, I was using bzip2 instead because it got slightly
better compression.  Some time in January, 2000, I found that some of
the files I had not changed in a long time, and some that I had just
edited, had become corrupted and I had to rebuild them.

Maybe bzip2 has improved since then, but my experience with it has
been jaded ever since, and I'd rather go for reliability over a slight
improvement in compression any day.

I may undertake an experiment and keep parallel bzip2 archives for a
while, but now isn't a good time for it.

On the other hand, I've been using bzip2 for a few executables since
that same time frame and, AFAIK, they work just fine, no corruption.

As I said, YMMV, and that's just my $0.02.
