First of all, make a copy of the backup file before attempting any
operation.  I suggest trying gzrt
(http://www.urbanophile.com/arenn/hacking/gzrt/gzrt.html).  I have not
tested it.  The output you will get for the weekly file is another gzip
compressed file.  Try what Stephane Bortzmeyer suggested on that file.

I'll also suggest not compressing a file which has already been compressed.
