I don't think repeated compression is a good idea. It can lead to file corruption.

I suggest to tar the file first and then apply a bzip2 compression on top of that.
Code:
tar myfilelog.log.tar myfilelog.log
bzip2 myfilelog.log.tar

BTW if you want to create a new file name each time you compress, then here is syntax:-
Code:
for i in {1..3}
do
  zip myfilelog.${i}.log myfilelog.log 
done

I hope this helps.

bundle

BUNDLE(1)						      General Commands Manual							 BUNDLE(1)

NAME

       bundle - collect files for distribution

SYNOPSIS

       bundle file ...

DESCRIPTION

       Bundle  writes  on  its	standard output a shell script for rc(1) or a Bourne shell which, when executed, will recreate the original files.
       Its main use is for distributing small numbers of text files by mail(1).

       Although less refined than standard archives from ar(1) or tar(1), a bundle file is self-documenting and complete;  little  preparation	is
       required on the receiving machine.

EXAMPLES

       bundle mkfile *.[ch] | mail kremvax!boris
	      Send  a  makefile  to Boris together with related and files.  Upon receiving the mail, Boris may save the file sans postmark, say in
	      gift/horse, then do

       cd gift; rc horse; mk

SOURCE

       /rc/bin/bundle

SEE ALSO

       ar(1), tar(1), mail(1)

BUGS

       Bundle will not create directories and is unsatisfactory for non-text files.
       Beware of gift horses.
