Good question. Well, a long time ago I tried to find out how to do it with
tar alone. However, I couldn't make it work. The result was the workaround
with the split command.
Of course, loosing one part would be a problem, but I don't think it is
more likely to loose one of those multiple files than loosing the entire
archive, which you had tried to create in your first approach.
