Please don't do that right now!  First of all, we don't back up .bz2
files, since they are all autogenerated.

We're currently about to figure out how to manage the transition to .xz
on kernel.org.

At the moment, I personally prefer the notion of removing the .bz2 files
(as opposed to .gz) in favor of .xz for two reasons:

a) the .gz files are the current original content.
b) gzip is a lot faster than bzip2, but xz is as fast or faster than
   bzip2 for decompression.  bzip2 is bigger than xz and slower, and so
   it doesn't have any unique reason to exist.
