I want to keep the original files I'm going to compress. Looking through the man file it looks as if I should use the option '--backup'. Unfortunately I can't really decipher the manpage correctly. Is backup the correct option, is there another I should use, or should I just copy the directories I want to archive? This reminds me of another question I have: when I append these files from the top level directory will it append the files under it as well?
