I have a very large XML database (2005) which I regularly backup and compress using 7zip (v9.20)

The resulting file size reduces from 15gb down to 364mb with option mx=9.
When I use MSSQLCompressedBackup-1.2-20110729_x86, zip64 compressed the same backup file down to 920mb, and bzip2 down to 613mb (both using level=9).

Is there any method or option that can more closely attain the same level of compression as 7zip is currently attaining?

    7zip is great unfortunately I don't have much time to devote to the project to add 7zip support.
